How do you multiply integers examples?

To multiply integers, just multiply the numeric numbers without the sign and place a sign on the product by recalling the above rules.

1. Example 1. 7 x 5 = 35.
2. Example 2. (-2) × (−4) × (−3) = −24; here, the number of multiplicands = 3 (odd number)
3. Example 3. (−4) × (−3) = 12; Here the number of multiplicands is 2 (even)

How to solve equations with properties of integers?

When you divide both sides of an equation by any nonzero number, you still have equality. For any numbers a,b,c,and c ≠0, If a= b then a c = b c. For any numbers a, b, c, and c ≠ 0, If a = b then a c = b c. Solve: 7x = −49 Solve: 7 x = − 49. To isolate x x, we need to undo multiplication.
