if 2 positive numbers are multiplied, then the product is positive. if 2 negative numbers are multiplied, the product is positive. if a positive and a negative number are multiplied, the product is negative.

It is the same as determining the sign of the product of two integers;+ x + = ++ x - = -- x + = -- x - = +ORIf only positive numbers are multiplied, the result is positive.If positive and an even number of negative numbers (for example, + x - x -) are multiplied, the result is positive.If positive and an odd number of negative numbers (for example, + x + x -) are multiplied, the result is negative.If an even number of negative numbers (for example, - x -) are multiplied, the result is positive.If an odd number of negative numbers (for example, - x - x -) are multiplied, the result is negative.Remember the rule:Product of a positive and a positive fraction is always positive.Product of a positive and a negative fraction is always negative.Product of a negative and a positive fraction is always negative.Product of a negative and a negative fraction is always positive.Examples:½ * ¼ = 1/8½ * -¼ = -1/8-½ * ¼ = -1/8-½ * -¼ = 1/8Source: www.icoachmath.com

Multiplying something by a negative number makes it change signs. A positive number multiplied by a negative is negative therefore a negative * a negative is positive.

Negative because product of 47 negative numbers is negative and product of three positive number is Positive , so negative*positive = 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.

The product of two numbers is the two numbers multiplied together. When multiplying a positive number and a negative number, the answer is always negative. For example: 7*-3= -21

When two negative real numbers are multiplied together, the product is a positive real number.

It is positive. Any product of an even number of negative numbers will be positive, regardless of how many positive numbers you have. Similarly any product of an odd number of negative numbers will be negative, regardless of how many positive numbers you have.

It is a positive. When you multiply a negative and a negative, it becomes a positive, then you multipy the positive with the other positive

The product of negative number and a positive number is always a negative. The product of two positive numbers, or two negative numbers, is always a positive.

No, the product of the multiplication of a positive and a negative value is negative.

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.

(The product of 33 negative numbers) x (2 positive numbers) = (negative sign) x (positive sign) = negative sign

No. The product of two opposite numbers is always negative. Negative x positive = negative and Positive x negative = negative

No, if a negative integer is multiplied by a positive integer, the product is negative. However, if both of the integers are either positive or negative, the product is positive.

Since prime numbers are defined as positive integers, any product of prime numbers will be positive.

no. a negative multiplied by a negative is a positive.

because you can get a positive number as EITHER a product of 2 positive numbers OR the product of the negatives of the SAME 2 numbers; the product of 2 negative numbers is positive.

The product of all those numbers will always be a negative number.

The product of two positive numbers or two negative numbers is a positive number.

Yes. A product is the result of one number multiplied by another. For example: 5 x -2 = -10 If you multiply two numbers of the same sign (+ positive or - negative), the product will be positive. For example: -5 x -2 = 10 (positive)

It depends on what the value of x is. If x is a positive number, then it will be negative because a negative number multiplied by a positive number is negative. If x is a negative number, then it will be positive because the product of two negative numbers is always a positive number.

No, two negatives multiplied together always form a positive number.

If you know that the product of 2 negative numbers is positive, then the product of 4 negative numbers has to be positive. The product of the first two negative numbers is positive and the next two negative numbers is positive. Multiplying the product of the first two numbers (positive number) and the product of the last two numbers (also positive), is a positive number times a positive number which is positive. Let a, b, c and d be negative numbers: (a*b*c*d) = (a*b)*(c*d) (-ve*-ve*-ve*-ve)=(-ve*-ve)*(-ve*-ve)= (+ve)*(+ve) = (+ve)

False. Either the product or the quotient of two negative numbers is positive.False. Either the product or the quotient of two negative numbers is positive.False. Either the product or the quotient of two negative numbers is positive.False. Either the product or the quotient of two negative numbers is positive.
