(-7)(-5) what’s the answer please help
Lina20 [59]
Hello!

Let’s do it step-by-step, shall we? Don’t worry! These problems can be a bit tricky but you’ll get it in no time! It’s really simple.

So, we have (-7)(-5)

This means that the problem will be multiplied because of the parentheses. They substitute the multiplication sign.

So, we have -7 (multiplied by) -5= 35

So your answer would be 35. Hope this helps :) and good luck!
