That is part of the basic rules of Math: A: Multiply a Negative and a Negative will result in a Postive. B. Multiply a Negative and a Postive will result in a Negative. BTW, unlike English grammar, rules of Math are true at all times.

The difference is that when you are multiplying a negative with a postive it would be negative. Lets say their both negative then it would be postive. Examples: - - = + - +=+ - - - = - - - - -= +

negative/positive is equal to a negative think of it like this positive times negative is negative...right? so negative divided by positive is negative or make an example: -20/5 is -4 not 4 good luck...

A negative + a negative + a negative equals a negative. Adding a negative number is equal to subtracting a positive number. For example: -2+(-2)+(-2) = (-2)-2-2 -2+(-2)+(-2) = (-4)-2 -2+(-2)+(-2) = (-6)

negative times negative is positive negative divided by a negative is a postive negative times a positive is a negative negative divided by a positive is a negative

A number greater than zero is a postive number because if you look at a negative and postive number line then you will see that the number greater than zero are postives because its just a postive.
