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

DedPeter [7]

Given, a = -65 and b = 8.

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 $(+)(-) = -$ .

So $(a)(b) = (-65)(8)$

= $(-)(+)(65)(8)$ = $- (65)(8)$ = $-520$

So we have got the required product.

Multiplication of a and b = -520.

The correct option is option C.
