    be careful: (-2)^2 is 4, but -2^2 is -4. pay attention to your order of operations: PEMDAS

    This is a tricky problem. In some programming languages, the Unary Minus has higher precedence than Exponentiation, so -4^2 = -16. If you are writing programs, you must be VERY SURE. The safest solution is to use parentheses to clarify meaning.
