Integer tiles are used to figure out the answer for adding and subtracting integers. Here is an example:
(-8) + (+2)= ?
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
(+2) - (+4) = ?
The positive four changed into a negative four
(+2) + (-4) = -2
