Answer: -57
Step-by-step explanation:
15 + ( - 72)
Distribute
15 - 72
When this happens, you subtract the smaller number by the bigger one, then put the sign that was on the bigger number on what you get.
72 - 15 = 57
Put a negative sign on 57
-57
15 + (-72) = -57
252 you multiply the 42 and 12 then devoid even by 2
N = 4.
I’m not sure if that was what you were asking though.
