Question

Help if you can its kinda hard

Answer 1

-9 + (-9) = -18

Explanation:

They start on -9 and end on -18. That means -9 has to be an addend and -18 is the sum.

-18 - (-9) = -18 + 9 = -9, which means the other addend is also -9.

Hope this helps!

(Also I don't think you need to add the parenthesis in the box.)

Answer 2

The equation would be -9+-9 = -18
