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.

Negative is the opposite of positive.

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.

What combination of signed numbers always leads to a negative number?

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.

Positive and negative what is the final result?

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.

Why is the product positive when there is an even number of negative factors?

Why is the product of a negative number and a positive number negative?

In math, a product is the result of multiplying. Multiplication is distributive over positive and negative numbers, which means, when a negative number is multiplied by a positive number, it always yields a negative result.

What operations will always produce a negative number?

Multiplication or division of two numbers of opposite signs: negative*positive, positive*negative, negative/positive, and positive/negative. Addition of two negative numbers: -5 + -2 = -7 Multiplying pure imaginary numbers of the same 'sign' : 5i * 2i = -10. -3i * -4i = -12. Dividing pure imaginary numbers of different signs (this comes from the fact that 1/i = -i, and i/i = +1)

Is this set of negative numbers closed under multiplication or addition?

Yes. The empty set is closed under the two operations.

What happen when you divide negative and positive number?

When you divide or multiply positive and negative numbers, you first do the division or multiplication as normal. The next step is to assess whether or not the answer will be negative or positive. If the two numbers of the question were the same (negative and negative or positive and positive) then the answer will be positive. If the two numbers in the question were different (one negative and one positive) then the answer will be negative. Thus, if you divide a negative number by a positive number, the result will be the same as normal division, but the answer will be negative.
