Integer Tiles
Integer tiles are used to figure out the answer for adding and subtracting integers. Here is an example:

(-8) + (+2)= ?

Since there is -6 left over that is the answer.
Subtracting Integers
We do not subtract integers we add the opposite. Here is an example:
(-8) - (+2) = ?
When changing it to adding you have to make the second number opposite of what it already is
(-8) + (-2) = -10
Another Example:
(+2) - (+4) = ?
The positive four changed into a negative four
(+2) + (-4) = -2

Homework
