Hi guys, i just needed to know was these answers correct or not

The one you put as (-13, -6) is incorrect, it is (-13, 6)

-2 * -3 = 6          -Two negatives gives a positive

The one you put as (-15,-4) is incorrect, it is (-15, 4)

-36 / -9 = 4    -Once again two negatives gives a positive.

The one you put as (-15,-3) is incorrect, it is (-15, 3)

-3 + 6 = 3

The one you put as ( -14, 2) is incorrect, it is (-14, 0)

-1 - (-1) = 0

Hope this helps you! It took a while for me to do it. Happy thanksgiving, here's a turkey!
