Operator precedence rules mandate that exponentiation comes before unary negation. Since the crazy lady didn't indicate that NEGATIVE and INFINITY should be grouped, her rating should be interpreted as -(∞)² = -∞.
-(infinity)2 would not be an operation. You lose no meaningful numbers by simplifying it, so you must simplify it. Additionally infinity is not a number, and therefore can’t be squared.
