The rules of negative numbers?
If you are talking about the multiplication rules than they would be; a negative times a negative is a positive a negative times a positive is a negative
Is the set of all negative numbers closed under the operation of multiplication Explain why or why not?
No. For a set to be closed with respect to an operation, the result of applying the operation to any elements of the set also must be in the set. The set of negative numbers is not closed under multiplication because, for example (-1)*(-2)=2. In that example, we multiplied two numbers that were in the set (negative numbers) and the product was not in the set (it is a positive number). On the other hand, the set of all negative numbers is closed under the operation of addition because the sum of any two negative numbers is a negatoive number.
Explain how you can find the sign of the product of two or more rational numbers?
Negative times negative equals positive. Positive times positive equals positive. Positive times negative equals negative. If you have more than two numbers, multiply the first two and then apply these rules to each successive number in turn.

Why is The product of a negative integer and a positive integer is always negative integer?
The rules for multiplying signed numbers may be formulated from the fact that multiplication serves as a shorthand notation for addition. For example, 4 x (−3), which means "4 times negative −3" is the same as the following: (-3) + (-3) + (-3) + (-3) = -12 Therefore, it follows that multiplication of a negative and positive number represents addition of negative numbers.

Does division and multiplication involve negatives?
Not by necessity, but multiplication and division aredefined for negative numbers.
What are the rules of cubing for negative numbers?
the same as all integer exponents, repeated multiplication the indicated number of times. Negative numbers when cubed yield negative numbers.
Why multiplication of negative numbers equals positive?
When you multiply any number by a negative number you reverse its sign. So positive numbers become negative, and negative numbers become positive. That is the meaning of negative multiplication; it is reversal. This is similar to the way that adding a negative number has the same effect as subtracting a positive number. Negative is the opposite of positive.
Is the set of all negative numbers closed under the operation of multiplication explain why or why?
No.When you multiply two negative numbers together, you do not get a negative number as the answer.
Is the set of negative integers closed under multiplication real numbers?

The short answer: That is the definition of multiplication with negative numbers.
Does a negative times a positive equal a negative What are the steps of multipyling negative and positive numbers?
Yes. In multiplication, the product is positive if the factors have the same sign,and the product is negative if they have oppositesigns.
Why does the product of 3 negative numbers equal a negative number number?
Because two negative multiplied together equal a positive. So after the first multiplication we have a positive and a negative. When we multiply these we have a negative.
What combination of signed numbers always leads to a negative number?
If you're talking about multiplication or division, then opposite signs will result in a negative number.
