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)

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

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'.

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.

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 same as +4 times +8. The product of two negative numbers is positive.
