Sargent Park 8-73 Math

Time for a new home

2006-09-06T20:19:00.000-05:00

With much regret and yet excitement the Sargent Park Math Zone has moved to a new site. The reasons for leaving are that Blogger in Beta is a much better service. Please continue to use this site to see what happened over my first year of blogging.

Former students I encourage you to continue to use you classroom blogs as a way to communicate with each other and the math blogging community.

I enjoyed it and am looking forward to seeing what will happen this year. Below you will find links to the new Math Class blogs for Sargent Park School. To the seven wonderful people who have subscribe to this blog. Come on over to the new site and continue the journey. Comments are always welcome and appreciated.

New Homes for.....

Sargent Park Math Zone This will be the new class hub. Students will find out what they need to do for Blogging assignments and have the ability to be interactive in their learning.

816 The new class blog for this classroom. Its 33 students will become members and have opportunties online to reach new levels of learning.

817 The new class blog for this classroom. Its 31 students will become members and have opportunties online to reach new levels of learning.

841 The new class blog for this classroom. Its 32 students will become members and have opportunties online to reach new levels of learning.

873 The new class blog for this classroom. Its 31 students will become members and have opportunties online to reach new levels of learning.

Students will also post to their classroom wiki to create A Grade 8 Math Guidebook. This is a new and exciting opportunity to create a manual of everything that they have learned. The students will include problems and solutions, their scribeposts and growing posts.

The Scribe Post Hall of Fame will be a place to showcase the best class scribes.

The Growing Post Hall of Fame will house the best Growing Posts that the students create.

I hope you take time to visit our new blogs.

Mr. Harbeck
Thanks for watching our journey..... but it ongoing

A new year Dawns

2006-08-30T09:42:00.000-05:00

It comes time to say good bye to some very terrific blogs. These blogs will remain alive as former students come back and reminisce about the previous year. I hope that this years students use these blogs as examples to help them with this years work. Good luck to my former students who now are in grade 9 and welcome the new group of grade 8's who will be learning math in new exciting ways.

The new class blogs for 2006 are

8-16
8-17
8-41
8-73

I would like to thank the students for being such excellent learners and using technology to enhance their learning. I could not have done this without them.

This Post has been inducted into the Growing Post Hall of Fame

Part One

3] Equivalent Fractions Has some good strategies on finding equivalent fractions. (Along with subtracting and adding.)

4a] Tim only has 3/4 of a bag of marbles while Ben has 4/3. If Tim and Ben were to combine their marbles, how much would they have altogether?
b] Kate had 9 3/9 of an apple pie, if she were to give you 5 2/3, how much would she have left?

5] I've commented on (873) Allysha, John and (817) Katho.

6] Adding & Subtracting [like] fractions
Equivalent Fractions
Both of these pages explain how to add/subtract (like) fractions.

Part Two
1]

I'm not sure if this is right or not !

3] TheMathPage.com shows you how to multiply fractions. It also shows you how to multiply mixed fractions. They use an easy to follow strategy aswell.

5] TheMathPage.com shows you how to divide fractions. Like the other link above, it shows how to divide mixed fractions. It also has some good examples using problems.

6] I choose Dhona's post from 8.16 because she has great pictures that explain fractions thoroughly.
I choose Genissa's post from 8.17 because she has really clear-drawn images which're simply made but are understandable.
I choose Tyler's post from 8.41 because he has an interesting and creative way of blogging. His pictures are also clear and easy to read.
I choose Aldrin's post from 8.73 because he is usually one of the first to finish, he also does a great job explaining and his posts are eye-catching.

7] Ms. Gavier has 4 brown cats and 3 white kittens. She has 6 1/4 pounds of multi-cat feed. How much pounds of cat-feed do each of her feline friends get?

I answered Helen's word problem from 8-16.

fractions growing post [part two]

.... wait

2.

- to multiply fractions you multiply the numerators together, then multiply the denominators together...

3. multiplying fractions - this site shows you how to multiply fractions, like the way we did in the class... it explains how to multiply fractions in a simple way..

4.

- when you divide fractions you reverse the second fraction then you multiply the numerator and then multiply the denominators together.. [ not a good explainer..!]

5. dividing fractions - this site shows you how to divide fractions and make it into simplest terms, and it explains how to divide fractions with mix numbers as well...

Number 1

Number 2

Number 3
Go to this site and play the game of finding fractions in their lowest terms, equvilant fractions .

Number 4
A) Farmer Dan, had been growing beans and corn. The next day, the beans had grown 3/4 and the corn had grown 2/3. How much did the plants grow altogether?

B) Johnny had 3 and 4/5 of a chocolate. Sonny took 2 3/5 of his chocolate. How much chocolate does Johnny have now?

Number 5
I did Alex M's, Ham (Mark's) and Aldrin's growing post questions.

Number 6
Adding and Subtracting Fractions: this site has a description of how to subtract denomenators, a caculator thingy and a game.

Part 2

Number 1
5/6 9/5
They are different numbers but to compare them first u must get a common denominator in the lowest term or the Lowest Common Denominator (LCD).
So the lowerst denominator that these 2 numbers could become is 30.
5/6 X 5 = 25/30
9/5 X 6 = 54/30 Now you can compare them.

Number 2

Number 3
Multiplying Fractions: This site lets you multiply fractions. It also lets you multiply mixed numbers and a fractions and mixed numbers multiplied by mixed numbers. Whenyou press multiply it gives you the answer and how it got the answer as well.

Number 4

Number 5
Dividing Fractions: This site lets you divide fractions. It also lets you divide mixed numbers and a fractions and mixed numbers divided by mixed numbers. When you press divide it gives you the answer and how it got the answer as well.

Number 6
I choose Aldrin's post from 8-73 because he does all his work first and makes them so they are very nice and people can't take them.
I picked Tyler's Post from 8-41 because I understood what he was talking about.
For 8-17 I chose Katho's Post post bevause of the pictures.
In 8-16 Annalyn's Post because it made sense.

Number 7
If it took me an average of 1 minute to run 1/6 of a cross country lap, how many laps would I have done if I ran for one hour and and thirty minutes?

I answered Ingrid's.

2006-04-30T19:10:00.000-05:00

You have to find the biggest number that can divide into the numerator and the denomenator evenly, so you can get the fraction in its lowest term.

2.) A mixed number is just a whole number plus a proper fraction. An improper fraction is a fraction greater than or equal to 1. Improper fractions and mixed numbers are similar because they both have more then one whole.

3.) This website explains what equivalent fractions are and how we know when they are equivalent or not. Also shows us how to reduce them into lowest terms. (click here)

4.) a. If I had 3/4 of a bag of cookies and my cousin gave me 1/3 of her cookies, how much candy do we have all together?

4.) b. If I had 2 1/5 left of my pizza and gave my sister 1 2/7 of my pizza how much pizza do i have left?

6.) This website explains how to add and subtract fractions wheather they have the same denomenator or not, and it also shows how to subtract a mixed number from a whole number. (click here)

PART 2

3. This website shows how you multiply fractions. It shows how you multiply in steps so you dont get confused and they explain it well. It gives many examples and at the end it gives you problems to solve. (click here)

5. This websites shows you how to divide fractions. It shows how you divide in steps so you dont get confused and they explain it well. It gives many examples and at the end it gives you problems to try and solve. (click here)

2006-04-30T17:42:00.000-05:00

Yay!!! I finished Fractttttttion growing post part one and two!!! I'm so proud... (even thought some of my answers are wrong?) hahahaha.. oh well...!!!

Part 2:

1. Right Answer: 1 4/5. I kinda get it now. My sister helped me and I really feel so stupid. It's just a simple answer cuz there's only 1 five in 9 so there's 4 left and the denominator. So yeah, 1 4/5.

Okay... Mr. H said nothing's wrong. It's just a second verison that uses a completely different thinking...

3. Multiplying Fractions --> This website shows you how to multiply fractions. This also shows the steps on how to do it. It explains some problems like how to reduce it in lowest terms, and how to do the shorcut. (You know like when you multiply high numbers.)

5. Dividing Fractions --> This website shows you how to devide fractions (obviously). It also shows the steps on how to do it. It explains how to devide any numbers in a fraction or a mixed number so yeah...

6. First, I chose Katho's post from 8-17 cuz i think it's simple and really easy to understand. It shows the main point of multiplying and dividing fractions and there's not so much blah blah blah....

Second, I Tyler's post from 8-41 cuz I think his post is so colorful anf full of life... hahahaha... not only that but the explanation is so simple and just like Katho's, you can understand the details he put on it.

Third, I chose Helen's post from 8-16 cuz her post is so beautiful... :) and and and it's so colorful and there's rainbow.. hahahahahaha... okay cuz her post is very detailed and there's a lot of explanation and if ever you get confused, I think just go to helen's post then you'll know how to do your math problem... I think...

And last but not least, I chose Ingrid's post from our room, 8-73 of course cuz her post is so simple and easy to understand just like the others and it's so organized.

7. Let's pretend that these red and green circles are my M&M's. I have 2 friends to divide it with. So how much of green and red M&M's do each of us get?

Like my M&M's? It's doesn't even look like one but watever.

I answered Helen's mother's day problem... and by the way... Happy mother's day.... uhhh... nevermind.

Part 1:

3. http://www.gomath.com/exercises/ReducingToLowestTerms.php

4. A) Hazel bought 3/4 of pepperoni pizza while Darlene has 2/3. If they add it all together, how many slice of pizza do they have?

B) Anne has 6 5/8 pieces of chocolate bars. She gave Zet 2 2/8 of her chocolates. In total, how much chocolate bars Anne have left?

Before we started class, we were given a paper containing the instructions on our next growing post assignment on Fractions. Mr. Harbeck explained what we had to do on this assignment, its a little different compared to the previous one. The first part of the assignment is due on Thursday, May 4th, then we will be recieving the second part of the post. Then we wrote down stuff on Lowest Terms, Mixed numbers and Improper Fractions. We also took notes on 'How to add Fractions' . After that, we were assigned 3 more pages (C-37, C-43, C-44) to do for the rest of the class/homework.

* Growing Post is going to be a little different than the last one on geometry. The last growing post you were expected to add material to your post on a daily basis. This will remain the same. A difference this time is that you will be expected to participate on other people's posts by leaving comments. The questions below are just an outline of what is needed in this post. Feel Free to add other information about fractions.

Fraction Growing Post Instructions Part 1
1. Use a picture and text to show that you understand what expressing fractions in lowest terms means.
2. How are improper fractions and mixed numbers the same?
3. Find a website or blog that explains how to create equivalent fractions or write fractions in lowest terms. Create a link to it and a brief description of what the site has to offer.
4. a) Write a word problem that involves adding these two fractions with the denominators of fourths and thirds and your answer is an improper fraction.b) Write a word problem that involves subtracting two mixed numbers.
5. Go to three peoples growing posts and answer their fraction problems by leaving comments. One of the three people cannot be from your homeroom!!
6. Find a website or blog that explains how to add or subtract fractions. Create a link to it and a brief description of what the site has to offer. Check out other students growing posts. If you like what you see leave a comment telling them what they are doing well. if you notice a mistake leave a comment on how to fix or improve the post.
End of Part 1.
* Due thursday, May 4th.

2. They are the same because mixed numbers and improper fractions both have more than one whlole.

3.This site talks about multiplying to create equivalent fractions:

4. a)a guy is ordering a pizza. he asks that it should be cut into fourths because he has four friens coming over for a game. one friend calls and asks if he can bring three friends over.The pizza's and friends arrive but each pizza is missing a piece. how many pieces of pizza are left?
(3/4 + 2/3)

4. b)the same guy is making waffels and invites a friend to join him. he makes 6 whole waffels but one guy only eats 1 1/2 waffles and the other only eats 2 2/3. howmant are left?
(1 1/2 + 2 2/3)

5. I did aldrin's, allysha's and dorito's in 41! hurray 4 me!

6. This site gives you step-by-step instructions on how to add and subtract fractionsand it has its own practice game!

EENNDD OOFF PPAARRTT 1

PPAARRTT 2 COMING NOW!!!!!!!!

3.this site is one iss sen befor. it doesn't use alot of words or any picturesbut it pretty much sumarizes what we did in class. it's even got a short test that i dare anyon too try.

4.

5.this site is pretty muchthe same site as tha last. you justread the first couple of paragraphs and you might end up being like aldrin.maybee not that mush but you'lll know everything there is and like last time there is a smalll test with a timer!!!

6.I choose Aldrin from 73 because of all the hard work he puts into his blogg. he probably sits for siix hours straight doing everything other people do that take us maybe less that an hour.

I choose Marielou's from 16 because of all the great pictures! overdoing it but using the spelling mistakes to trick or not was a good idea!

I choose Rebecca G's because she is the farthest ahead (so far) and has pretty pictures (hers maybbe good but aldrin is the KING)

I choose DION from 41 because he has wwwaaaayyy more and better stuff than aldrin and pie! ilke pie! pluss he has lots of cool animations!!!

OMG!!!FRACTIONS!!!
1.
.

2.They are the same because they are still equal the same decimal like say .55

3. Shows and tells what Lowest terms means... and other stuff that has to do wid math http://www.superkids.com/aweb/tools/math/fraction/reducing/howto.sht

4. a.) 3/4 + 2/3= 1 5/12
b.)Unknown man wanted to know how much flour he should put in his batter so her measured it and got 2 1/3 when it's suppose to be 1 1/3. Subtract the two fractions inorder to find out how much flour is the extra amount.

5. commented on: Layco's 8-73, Rebecca.G from 8-17, and........ kahlah120 from 8-41

6. Tells you some tips/info on add.sub. and even multi.and divide for fractions :D There now eveerryybodys' happy :D:P
http://www.superkids.com/aweb/tools/math/fraction/

Part 2:

2.When you multiply fractions the fraction gets smaller.
Example 1): 1/2 x 3/4 = ... You first have to change the fraction 1/2 until u get an equal denominator that 4 could fit into as well as 2 so like this... 1/2 (x each by 2) = 2/4 and 3//4 (x each by 1)= 3/4 then 2/4 x 3/4 ....Now u just multiply going across like this.
1 x 3= 3
} = 3/8, and that's ur answer. ^_^
2 x 4= 8

2) And here is a pictoral example....

3. Here u go the exact sameone me put on the part one, cause' well... it has the same stuff in it already and I already mentioned what it bout.
www.superkids.com/aweb/tools/math/fraction/

4. When u divide ractions they get bigger I think.
Example 1):

P.S. on #4- not sure If I did any of that right or not. :P

5. Once again here is the same site I used for everyone of these q's that have this question... But I'll tell it again it has information ... a bit on how to divide fractions and I think it shows a few examples on it too. It also has stuff on adding,subtracting, and multiplying fractions. There is even some games u can play but I'm not quite sure if they have on fractions or not.
www.superkids.com/aweb/tools/math/fraction/

6. The 4 people I chose to be in the Growing Post Hall of Fame are...
Ingrid from 8-73, because her pictures are clear and her work is easy to understand, and because I like the little kitty picture at the bottom :P
Michael S 8-17, because his pictures were very clear and easy to see and I could understand almost all of his work. (P.S-u'll have to scroll doen to the bottom to find his post,sry.)
Yvanne 8-16, because I liked the way she did her pictures and they were clear and easy to read & understand. (P.S.- U'll have to scroll down somewhere near the bottom again to find her post :/)
and...
Kim from 8-41, because her work is easy to understand and her pics. r easy to see, and because it looked like she was the only one done...well besides Squeaky_Cheeks 74 but I think that person's was for sumethin else. So yeps. ( Scroll down, I don't think I need to tell u people cause it's like just there.)

7. Okay Unknown dude made 2 piles of his homework, one pile math the other LA. His math pile has 3/4 of work to do while the LA pile contains 4 stuff to do. How much homework does Unknown dude have all together? (REMINDER- Incase u forget, u have to multiply.)

And the person's Q I answered was http://sp873math.blogspot.com/2006/04/zhettesus-fraction-growing-post-ins1-2.html.

8. I chose Ingrid from 8-73 for the Growing Post Hall of Fame.

1)

RECTANGLE
Area = L x W
= 4 cm x 8 cm
= 24 cm

2)
TRIANGLE
Area = L x W / 2
= 4 cm x 8 cm / 2
= 24 / 2
= 12

3)
The size of the triangle is half the size of the rectangle. If you divide the size of the rectangle by 2, it will be the size of the triangle, and if you multiply the size of the triangle by 2, you'll get the size of the rectangle.

1. The area of a rectangle is found by multiplying its length and width. The formula would look like this: l x w = A

2. The area of a triangle is found by multiplying its height by its base. To find the height of a triangle look for a right angle. Once you multiply the base and height you divide the total by 2. The formula looks like this:

The relationship between the area of a triangle and the area of a rectangle is that every triangle is half of a rectangle.

4. Complex Figures

5. To find the area of a parallelogram you need to find the height and multiply it by the base. this is different than a rectangle. In a rectangle you have the height and base (due to the right angles in each corner). You multiply lenght times width. Here are three pictures that shows the relationship between the rectangle and parallelogram.

today in class we continued working on the piece of paper with 12 squares. in the 4th square under transposing, we wrote:

4(2x + 2) = 5(x + 7)
8x + 8 = 5x + 35
-5x - 8 = -5x - 8
3x/3 = 27/3

x = 9

in the 5th box under transposing, we wrote:

-there is a variable on both sides of the = sign
-use the distributive property to get rid of the brackets
-variables go left
-integers go right
-solve 1 step equation

then after that, we had to work on page 41 in the "sammy the seal" booklet.

2006-02-27T19:39:00.000-06:00

today in class we folded a piece of paper into 12 squares. On the first square we wrote collecting like terms. Then we opened it and we wrote in the 1st row in the 1st square:

3x-3+6x+9=24
3x+6x-3+9=24
9x+6=24-6
9 -6 9

x= 13/9 =2

we wrote:
- choose 1 of 2 terms
- circle them
- add like terms
- solve the equation when you have only 1 of each term

we did another example:

-2x-3x+3+2=10
-5x+5=10 -5
/-5 -5

we wrote:
- circle the first term
- find like terms
- put the like terms together
*cancel using integer rules

we went onto something new, transposing:
6x+5=2x+13
-2x -5 = -2x -5
When you simplify it becomes
4x/4 = 8/4 x=2

6(2)+5=2(2)+13
17 = 17

we wrote:
- you need the variable (letter) on the left and numbers on the right
- cancel the right variable with its opposite
- cancel right integer with its opposite

then we had to work on the 'sammy the seal' booklet and finish page 40

Today in class we corrected the homework we had yesterday, not a lot volunteered to go up and answer them though.
Then we took down notes on The Distributive Property.

This is pretty simple and easy to understand.

Uhh then we have page 41 in that booklet for homework.

That's all : ). I think?

what does z equal?

2006-02-21T20:58:00.000-06:00

Heres a question for anyone in 8-73. Show your work too. Post your answer in the the comments. Use the following information given to figure out the value for z. The equation isn't spaced, so you can use your head more. The question is also different from the ones taught in math class.

This is what we did today in math. We reviewed Like Terms. We also learned that we put the terms in their own "bags"

e.g1

2p+7p
two pears plus seven pineapples equals...9 pears ( both pears, same bag)
=9p

e.g2

3m+n+4n-m

three mango's plus a nectarine plus four nectarines subtract a mango

Serperate the different fruits
3m-1m= 2m

4n+1n= 5n

2006-02-20T16:46:00.000-06:00

the first thing we did in class was take down what we should have in our math section for our electronic portfolios.

then we took notes on collecting like terms.

- Terms that have the same variable parts are called like terms.

E.G1 ;; 3x + 7 = 40
Add 10x/ 10 ... 40/ 10
x = 4
3(4) + 7(4) = 40

E.G2 ;; 4x + 6 - 2x -9 = 9
4x - 2x + 6 - 9 = 9
2x - 3 = 9 + 3/ 2
x = 12/ 2
x = 6

You want 1 variable and 1 integer term on each side. After you have simplified
3x2 + 2x - x = 5x
3x2 - x2 + 2x +5x
2x2 +7x

aaand... we have pages 6.6 / 6.7 [ 1-18 ]
and 6.8 [ 1-20 ]

I created a post on the weekend all about the algebra you are doing. I am reposting it for your amusement. Please complete as much of this as you can and leave a comment behind about how you did.

Remember me Grade 8’s. Since I have been gone …only two days you must be missing me. Even if you are not missing me here are some excellent links to reinforce your learning.

The foundation to understanding algebra is to know integers. Here are two links that will reinforce what you need to know.

Try this Integer Quiz. If this is not familiar to you remember your order of operations and try again.

From this link you can see a movie on adding and subtracting integers. It is well done. If this link does not bring up the movie immediately click on the adding and subtracting integer link on the page.

Your first algebra lessons are dealing with words like term, variable, expression and equations.

Here are some helpful resources for you.
Extra help words to expressions
Extra help on variables and expressions

Here are three quizzes to see how well you did.

Substitution algebra
Solving Equations using Addition or Subtraction
Solving Equations using Division or Multiplication

Remember Leave comments to tell me how you did.

Now that I have seen that you guys are scribing. There are some excellent scribes going on and I assure you they will get better. You just have to push around each other on the blog. That’s the evolution of a blogger right there. You guys have to compete with each other to see who’s the best blogger out there. Hahahaha.

There are plenty of Examples of scribing.

Some advise to bloggers. You need to be prepared to put a post up to the blog. People are counting on you to keep the scribe alive. If you are having difficulty post a blog and then go back in and edit the scribe.

To the scribes fellow classmates, If the scribe needs to have information added to it, post comments and add information you think will be helpful.

You all are doing a great job. I miss being at school. This is my link to you right now. Keep me informed and I will add comments if I can.

2.During these activities, we learned the order of operations in a grade 9 math question. We had to box groups with its chaperone too in the questions. The chaperone is the symbol to the left of each group.
Example:
[(-2)(3)] [+ 2(-3)] [- (6)(1)]=
--------- --------- ----------

2006-01-30T14:55:00.000-06:00

Scribes in Mesopotamia used a stylus and clay tablet to keep track of may things. If you are the blog scribe you are to do the same for math class.

So... when it's your turn to be scribe, try answering these questions in your blog:

What did we do in class today?
What did we learn during these activities?
Was this new information or something I've seen in math or another class before?
Was the material difficult or easy to understand?
Is there something that I still don't understand and could ask my classmates to explain?
Did anything else happen during class that would be fun to keep a record of?
Are there any links out there to explain the concepts taight in class?

When you are done your post please pick another student to be tomorrows scribe.
Make this a fun assignment.

How much effort you put in it is up to you.

A. p/w=56 pounds = 78.8 = 56
140 pounds 140 100 % 140 x 56 divided by 100=78.8 78.8 x 0.56=44.
I should have put total pounds under 56 pounds, and I should have put 56 over 140. I also should have put 0.4 over 100 %. Last thing i should have done was 56 divided by 140 = 0.4 then moved the decimal 2 places to the right which = 40. The answer is acually 40 % of 140 pounds.

1. To successfully do percent problems you need to know the following:

1. What is the question.
2. Answer the question using a simple sentence answer (using a blank for an answer)
3. What is the part and the whole? Create a word ratio.
4. Set up a proportion that looks like this part/whole = %/100%
5. The last step is to ask myself does my answer look right? If it does I can use the cross products to check if my answer is correct!

Correct Question
On an aritmetic test John received a grade of 80% He solved 24 problems correctly. How many questions were there on test?

John's test was out of __________.

On an aritmetic test John received a grade of 80% (The percent) He solved 24 problems correctly(The part because it is not the complete test!!). How many questions were there on test?

The word ratio is
questions correct/total questions
24/? = 80%/100 b therefore 24 x 100/80 = 30
There are 30 questions on the test. (30 x 80 = 24 x 100)

A question I got wrong was
The original price of the sofa was $500 It is now on sale for $440. What was the percent decrease?

The percent decrease was _______.

The original price of the sofa was $500(The whole) It is now on sale for $440(The Part). What was the percent decrease (The UNKOWN)?

sale price/origional price = percent of sale $ /100% 440/500 =88%/100%

My Mistake was to say the 88% was the percent decrease. I needed to subtract the 88 from 100 to get a difference of 12%. There fore the percent decrease between the sale and origional price is 12%.

When adding a positive (+) and a negative (-) number, the answer is always positive. e.g. 7+(-5) = 2
You can change the addition symbol to a subtraction one and convert the negative number to a positive to have 7 - 5 = 2.

When adding numbers with the same symbol, the answer has the same symbol aswell.
e.g. (-4) + (-3) = -7
or 4 + 3 = 7

When subtracting a negative number from a positive number, the answer is always negative. e.g. 6 - (-6) = 12
You can also change the subtraction symbol to an addition one and convert the negative number to a positive number to have 6 + 6 = 12.

When subtracting numbers with the same symbol, the answer also has the same symbol as well.
e.g. (-4) - (-3) = -7
or 4 - 3 = 1

When multiplying or dividing numbers with the same symbol, the answer is always positive.
e.g. 11 x 3 = 33

When multiplying or dividing numbers with different symbols, the answer is always negative.
e.g. -10 x 1 = 10

A positive number and another positive number has a result of a positive number when multiplied or divided. A negative and a negative number also results in a positive number when multiplied or divided. Examples:
5x5=25
5 divided by 5=1
(-5)x(-5)=25
(-5)divided by(-5)=1
A postitive and a negative number or the other way around multiplied or divided results in a negative number.
5x(-5)=-25
5 divided by (-5)=1
Two negative numbers added together results in a number decreased and not increased.
(-5) + (-5)= -10
I'm too lazy to put the other stuff down.

A foot is 12 inches, so 12+12=24 so the length is 24 inches and the width is 12+4=16 so the width is 16 inches. So the Ratio is 3 : 2.

$8x4=$32
20%-.2
.2x32=6.4
$32-$6.40=$25.60 is the cost of Sami's parking cost.

5 grids x 25= 125
amount of shaded units=62
62--- =49.6%125

Discount is what you get off the normal price and the sale price is what you get when subtracting the fiscount from normal price.

50% of 70=35
10% of 80=8
5% of 80=4 -half of 10%
30%=8x3=24
35%=24+4=28

Sami's parking cost $26.60.
8 x 4 = 32
20% of 32 = 6.4
32 - 6.4 = 25.60

5x5x5=125
62 squares are shaded
62 divided by 125 = .496
.469 x 100 = 49.6 [rounded of = 50]
