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.
If the signs of both numbers are the same, the product will be positive. If the signs of the numbers are different, the product will be negative.

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)
If two numbers have the same sign, their product is positive. If two numbers have opposite signs, their product is negative. So the answer is 'yes'.
Yes. In multiplication, the product is positive if the factors have the same sign,and the product is negative if they have oppositesigns.
If the signs of both numbers are the same, the product will be positive. If the signs of the numbers are different, the product will be negative.
negative time negative equal positive
No. The sum of two negative numbers will always be a negative number. If, however, you multiply the numbers, their product will be positive.
The product of two negative numbers is a positive number. Ergo, the product of the square of a number is equal to the square of its negative equivalent.
no it doesnt. two negative numbers equal a negative number. two postivie numbers equal a positive number. one negative and one positive number equal a negative number.

A negative number TIMES a positive number will equal a negative number. A negative number DIVIDED BY a positive number (or vice versa) will equal a negative number. With addition and subtraction, it all depends on what the numbers are.
If two numbers have the same sign, their product is positive. If two numbers have opposite signs, their product is negative. So the answer is 'yes'.
Two negative numbers added together 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.
