    well 3 is not the right answer to evaluating -2^2+2 let's try to take it slow you are to apply order of operations there are no grouping symbols so let's do the exponents the exponent is only on the 2 if were to be on the -2 it would look like (-2)^2 but we have -2^2 so first exponents what is 2^2?
