The product of two positive or negative integers is positve and then the product of a positive and negative integer is negative.

-  positive x positive = positive
- negative x negative = positive
- negative x positve (or vice versa) = negative.

Example:
1. 5 x 7= 35
2. -7 x -5= 35
3. 7 x -5 = -35
