Question

Which expression is equal to 20 - (8 + 5) + 4?

Answer 1

We need to follow PEMDAS

first is Parenthesis, which we have (8+5)

8+5=13 and we are left with 20-(13)+4

Distribute the negative to 13 to get 20-13+4

Addition comes first so add 13+4 to get 17

And then solve 20-17

Your answer is 3.
