Question

Simplify the problem below.

-5 × 9

-21 + 6

Answer 1

-5 * 9 ....just multiply them and since one is positive and one is negative, the answer will be negative....so the answer to this is -45. Just remember, when multiplying, if the signs are different, then the answer is negative, but if the signs are the same, then the answer will be positive.

-21 + 6.....if the signs are different, you subtract and take the sign of the larger number...so the answer to this would be - 15. If the signs would have been the same, then you would have added and kept the same sign
