Question

-12 + 4 I need some help I have to learn this

Answer 1

The answer is -8.

Try switching the signs at first. For example : -12 + 4 would become 12 - 4 and the answer to that would be 8, then switch the signs back and you would get -8. Not sure if that works 100% of the time but it helped me until I had it down.

Answer 2

-12 +4 = -8.

-12, -11 (+1), -10 (+2), -9 (+3), -8(+4).

Hope this helps.
