If you multiply a negative number with a positive number, the result will be negative. If you multiply two negatives, the result will be positive.

Not by necessity, but multiplication and division aredefined for negative numbers.

No.When you multiply two negative numbers together, you do not get a negative number as the answer.

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.

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

It can also include addition and multiplication using negative and positive numbers.

The short answer: That is the definition of multiplication with negative numbers.

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.

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.

If you're talking about multiplication or division, then opposite signs will result in a negative number.

Yes. In multiplication, the product is positive if the factors have the same sign,and the product is negative if they have oppositesigns.

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.

Due to the sign rules for multiplication, if you multiply several negative numbers, you'll get a result that is alternately negative, positive, negative, positive, etc.

Division and multiplication work the same when working with negatives. Both numbers negative = positive Both numbers positive = positive One number negative, and one positive = negative So, 63 divided by 7 equals 9, but one of the numbers, the 7, had a negative sign... so the answer is negative 9 or -9

The Greatest Common Factor is asking for the largest number. I conclude that positive numbers are larger than negative ones.

Positive numbers are greater than zero, negative numbers are less than zero. There are a few few differences in how they are manipulated - particularly in multiplication or inequalities - but in most respects they are treated similarly.

There are two multiplication problems that equal 94 (not counting negative numbers): 1 x 94 = 94 2 x 47 = 94

It is possible to live a long and productive life without ever multiplying a negative number outside of a classroom.

If you mean the set of non-negative integers ("whole numbers" is a bit ambiguous in this sense), it is closed under addition and multiplication. If you mean "integers", the set is closed under addition, subtraction, multiplication.

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.

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)

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

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.

The Abelian or commutative property of the multiplication of numbers. It is important that both "multiplication" and "numbers" feature in the answer. Because, it is applicable to multiplication but not, for example, for division. It is applicable for the multiplication on numbers but not matrices.
