Question

`8 / (7 - 9) * (4 + ( - 4))`

I got the answer -4, but when I typed it in the calculator to check, it said 0. Can anyone help me?

Answer 1

8 ÷ (7 - 9) * ( 4 + (-4) ) <--- notice that bolded part.

4 + (-4) = 4 - 4 = 0.

after that, you're pretty much dividing and multiplying by 0, so

whatever ÷ whatever * whatever * 0 = 0.
