If you are multiplying negative numbers, an odd number of factors will have a negative product. An even number of factors will have a positive product.

Yes. The product of an odd number (21, in this case) of negative factors will be negative; if the number of negative factors is even, the product will be positive.

negative

even

Positive.

It will be even.

If an even number of negative factors are multiplied together (such as 18 factors), the answer will be positive. If there are an odd number of negative factors, the answer will be negative.

positive

The product will be positive in this case.

The product is also a whole number. If the (number of positive factors) minus the (number of negative factors) is zero or an even number, then the product is positive. Otherwise the product is negative.

The sign of the factors. These are the rules: * If there is a zero factor, the product is zero. * If there is an even number of negative factors (two, four, six, etc. odd factors), the product is positive. * If there is an odd number of negative factors (one, three, five, etc. odd factors), the productd is negative.

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.

When you multiply numbers together, the factors of the product are the factors of all of the multiplicands, and every even number includes at least one factor of 2.

If there is any zero in the set of integers, their product is zero.If there is an odd number of negative integers, then the product is negative, whereas if there is an even number of negative values, the product is positive.

The product is negative. An odd number of negatives means the answer will be negative. An even number of negatives means the answer will be positive.

No. Just try it out with 2, or 4, negative numbers.

The product is positive.If the number of negative factors - 4 in this case - is even, the product is positive, Otherwise, the product is negative.Note: Your question has been edited for clarity. If your question was different, please ask it again.

Yes because the product of each pair of negative numbers must be positive.

A positive integer.

At least one of the factors of an even number must be even, because the product of odd factors is always odd.

Any 2 negative numbers, whether even or odd, when multiplied are positive

Yes, it is. Any whole number times an even number will be even. This is because whole numbers can be represented as the product of their prime factors. Every even number contains 2 as a prime factor (thereby excluding all even numbers above 2 from being prime.) Additionally, the product of any two numbers is equal to the product of their prime factors. This means that the result of multiplying an even number by a whole number will always have a prime factor of 2, making it an even 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.

Count the number of negative values. If that number is even, the answer is positive and if it is odd, the answer is negative.
