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.
The numbers and the operation of multiplying is called a multiplication operation. The end result is called a product.

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.
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
In multiplication, the numbers that are being multiplied together are called factors. Multiplication is the third basic mathematical operation of arithmetic, after addition and subtraction and before division.
No.When you multiply two negative numbers together, you do not get a negative number as the answer.
It depends on the operation and values of the positive and negative. For example, in multiplication or division a positive and negative will be a negative. In addition or subtraction, it depends on the absolute value of the original numbers.

It is multiplication
Multiplication.
Not by necessity, but multiplication and division aredefined for negative numbers.
The numbers and the operation of multiplying is called a multiplication operation. The end result is called a product.

Yes.natural numbers are closed under multiplication.It means when the operation is done with natural numbers in multiplication the sum of two numbers is always the natural number.
the same as all integer exponents, repeated multiplication the indicated number of times. Negative numbers when cubed yield negative numbers.
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.
No, it is not.
