Answer: -3

Explanation: To subtract the integers -15 - (-12), it's important to understand that when we have minus a negative, we can change it to plus a positive so -15 - (-12) becomes -15 + (+12).

So starting at 0 on our number line, -15 moves us 15 units to the left and +12 moves us 12 units back to the right and we end up at -3.

So -15 - (-12) or -15 + (+12) is -3.
