Question

I need a explanation and a answer to the problem plzzz

Answer 1

When multiplying the 2 and the -12 it would be -24, not 24. Which if my mental math is correct, would make the answer 6

Edit:

Note that subtracting a negative is the same as adding the absolute value.

so:

-24-(-30)

changes to

-24+30

and it equals

6
