If a = − 65 and b = 8, the product of a x b models which rule for multiplying integers? What is the product?

We have to find multiplication of them.

a is negative and b is positive. When we multiply them, we know that the multiplication of positive and negative is negative. That means $(+)(-) = -$ .
