Answer:
-18
Explanation:
You have to follow the order of operations so first off, we'd do -(32-12) which is negative twenty.
Now we're left with;
-20 + 4/2
Here we're going to do division before we add so,
4/2 is 2
All that's left would be,
-20 + 2 which equals -18
Hope that helps, and have a great day!
