A negative number multiplied by a negative number gives a positive product.
EXAMPLE : Find the value of (-3) x (-4)
-3 x (4 - 4) = -3 x 0 = 0....expanding the brackets gives
-3 x 4 + (-3) x (-4) = 0
-12 + (-3) x (-4) = 0
Therefore (-3) x (-4) = 12 which is a positive number

What is the rule for multiplying a negative times a positive number?
If two numbers are multiplied and one of them is negative, the answer will turn out negative. If the two numbers being multiplied are either both negative or both positive, the answer will turn out positive. Example: -2 * 2 = -4 -2 * -2 = 4 2 * 2 = 4
When multiplying binomials that turn out negative do you add or subtract exponents?
When multiplying numbers with exponents, you add the exponents.
Negative 1 squared in parenthesis?
(-1)2=1 all squared numbers turn out positive and 12=1 (-1)2=1 all squared numbers turn out positive and 12=1
Why don't negative numbers have square roots?
They can, but they are called imaginary numbers. This is because a "square" of something is the number that, when multiplied by itself, will equal the first number. A negative multiplied by a negative equals a positive, and positives can't turn into negatives on their own, so there are no square roots of negative numbers.
Why does multiplying two negative numbers yields a positive number?
cause with negitives, once they are multiplied it cancles out. We say the multiplication is a short hand of a repeated addition. For example 3(5) means the number five shows up three times in the addition such as 5 + 5 + 5. So to turn (-2) + (-2) + (-2) + (-2) into a multiplication we count the times that -2 takes place in the addition, and we write 4(-2). If we have -4(-2), it means that we are looking for the opposite (or the negative) of 4(-2), because the first number in a multiplication is just a counting number which is always positive. Therefore, -4(-2) = -[4(-2)] = -(-8) = 8. Thus, we can say multiplying two negative numbers yields a positive number.
