Integers

The way to do integers is you do the opposite to the number like 5 on a numer line. The integer of that is mines five so pretty much the interger is the opposite of the number.

EXAMPLE

5 interger -5

23 interger -23

The key word you should think of when dealing with integers is opposite.

Equations

The way to do equations like 2+b=4 is you do opposite operations on b and 4 so b-2 =o and 4-2=2 so you know your answer is two.

Example

6-e=3

0=9

answer 9

Check

6-e=3

6-9=3

3=3

9=e

The way to do check is write down the problem than on the next line you write your answer were the equation was. Then if it is correct you write the answer with a equal sign next to the answer . Then you say the variable =the answer to the variable.

Hints

One hint in writing equations is to make sure all the = signs are lined up. Another hint is when doing multiplication you have to keep the signs and answers on one line and all together you have two lines.
