Why Does A Negative Times A Negative Equal A Positive
Olivia Luz
Specifically it can be proven using the equation x a b a b a b where a and b are any positive numbers and x is unknown via factoring and reducing the expression.
A times 0 0 and a left b c right ab ac. The fact that a negative times a negative equals a positive can be proven mathematically using algebraic manipulation. A negative times a negative is two reflections which is the same effect as multiplying by a positive. The precise logical argument as to why negative times negative should be positive once we agree that 2 times left 3 right 6 via repeated addition and left 3 right times 2 6 via a belief in commutativity that negative times negative is positive is a forced logical consequence of these next two basic beliefs of arithmetic.
