Work Step by Step
Order of operations tells us to consider the stuff inside of the brackets first. Once within the brackets, we have to figure out what to do next. The (2-3) is in parenthesis, so we know to do this operation first, giving us -1. This leaves us with 2[2-(-1)-2]. A negative minus a negative is addition, so this simplifies to: 2[2+1-2]. We now add together all like terms inside of the brackets. 2+1 is 3, and 3 plus -2 gives us 1. We now have: 2. When a number is outside of a set of brackets or parenthesis with no operation (for instance, no minus or addition sign) we know to multiply, giving us a final answer of 2.
