Question

Can u guys explian this problem to me:(-9)(-6)(15)(-7+7)

Answer 1

(-9)(-6)(15)(-7+7)

Negative numbers multiplied by negative numbers equals to a positive number.

(-9)(-6) = (9)(6) = 54

(-7+7) = 0

(54)(15)(0) = 0

Remember, anything times 0 will always be 0

Answer 2

$-9 \times - 6 = 54\\54\times 15 = 810 \\810(-7+7) = -810(0) \\810 \times 0 = 0$

Your answer is 0
