Question

What can you conclude about two integers whose product is positive?

Answer 1

Step 1: Both integers can be positive.

Ex. Find the product $3\times 5$

The product is 15 (positive).

(The product of two positive integers is positive.)

Step 2: Both integers can be negative.

Ex. Find the product $(-3)\times (-5)$

The product is 15 (positive).

(The product of two negative integers is positive.)

Final Answer: If the product of two integers is positive, two integers must be of same signs either both positive or both negative.
