John's Scribe Post

Last Monday, we learned how to divide fractions.

There's 2 ways of doing this.

Elementary or Junior High

If you don't know how to do the Junior High, read & view this scribe post!

There was no negatives in the equation so it's a positive.

'How many times can 3 go into 12?' = 4

Now listen up, this part is important.

If 1 number is negative, it's like this :

(-12) ÷ 3 = (-4)

But if 2 numbers are negative, it's like this :

(-12) ÷ (-3) = 4

So here's the SIGN RULE.

2 negatives = positive answer

1 negative = negative answer

It doesn't have to be 1 or 2 only, odds & evens too.

1-3-5-7-9-11

2-4-6-8-10-12

Dylan`s Multiplying integer scribe post

Hey every body what well i got or a scribe post today was the odd numbers of pages 296 and 297 so heres the first two


this is what i did for the odd questions on 296
the first one was this

1.Darcy modelled (+7) × (+3) on a number line by drawing seven
arrows. Ishnan modelled (+7) × (+3) on a number line by
drawing only three arrows. Explain Ishnan’s thinking

My answer was this : She is showing 7 groups of 3 which 7x3 really is

The last question on 296 was some what the same and here it is

2.Without doing any calculations, Wei said that -19 and +27 have
the same product as +19 and -27. How did she know?
again my answer was: She knew this because -19 and 19 have the same value but different place values the same goes for 27 and -27

thats what is did for question 5 a

here's question 5 b

the last and final question is the easiest
A) 10x4=40
B) 2x9=18

Integer Subtracting; Range (-9) to (+9) (c) 2nd column

1. (+7)-(+5)=2

 

 2.(-5)-(-5)=2

3.(+6)-(-9)=15

4.(+6)-(+4)=2

5. (-7)-(+8)=15

Standard form is when you remove the brackets and the redundant plus sign or in money form the "and" sign. (Sorry about picture quality taken with and Ipod.)

Mark Asino's Integer Scribepost

-Standard Form is when you remove the brackets and the sign 

-Grade 7 form is when you keep the brackets
1) (+3) + (+6)

2) (-6) + (-1) 

3) (+3) + (-2)
