Work Step by Step
This is an order of operations problem. There are brackets, so the first operation is the stuff within the brackets. Within the brackets, we see 2-3 in parenthesis, so we do this first, finding that 2-3=-1. This gives us the following:
2[2-(-1)-2]
A key rule to remember is that subtracting a negative is the same as addition. Thus, we find:
2[2+1-2]
=2[3-2]
=2[1]
=2
