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.
