**-NEGATIVE is blue**

**+POSITIVE is red**

**BOTH=zero pair**

Remember the song

*"use a zero pair when subtracting something*

*that is not there"*

(use this song it will help)

Grade 7 way

Using brackets

**( )**

Standard form

Not using brackets

**( X )**

If you are having trouble and you don't understand intergers use a number line or think of it as money.(try it out right now)

Even= When you have an even number of negative factors the product is POSITIVE

ODD= When you have an odd number of negative factors the product is negative

Examples:

-11-(4)=-7**- - - - - - - (- - - -**

**)**Take this away

22-(-9)

22-+(-9)=31 **+ + + + + + + + + + ****+ + + + + + + + + + + + **

**- - - - - - - - -**

** + + + + + + + + + **

These are supposed to be zero pairs

(sorry about the whole zero pair thing )

-9 +4 +(-9)

-9 +4 -9 Sorry I tried making a number line but it didn't work

-9 -9 +4 But a number line is a good strategy-for me anyway

-18+4= -14

example of multyplying integers:

7X-2

Forget the signs and multyply normaly

7X2= 14Now you can go back to the signs

You know that a positive times a negative is a negative

So your answer is obviously -14

Sorry that I didn't do any of the chapters
