Subject: How do we model the cube of -9 less the square of -8
Mimi, We had a Math contest recently and one of the controversial question is " How much is the square of -9 less than the cube of -8. Is there an answer to this? Is the question valid? Do we give such questions to students? Is this mathematically sound? Thank you and hoping for input on this matter. Sincerely, Mrs. Virgie G. Esteves
