Explanation: You’ll have to multiply the numbers. 12x6 = 72. 12x-4 = -48.
72 + (-48)
You remove the parentheses because when there’s a “+” in the front of an expression in parentheses, the expression remains the same.
Therefore, it’s just 72-48. Subtract that and you’ll get 24. Hope this helps! (:

Answer:
2/405
Step-by-step explanation:
Simplify the following:
(-2)/9×((-1)/3×1/3)/5
(-1)/3×1/3 = (-1)/(3×3):
(-2)/9×((-1)/(3×3))/5
(-1)/(3×3)×1/5 = (-1)/(3×3×5):
(-2)/9×(-1)/(3×3×5)
(-2)/9×(-1)/(3×3×5) = (-2 (-1))/(3×3×5×9):
(-2 (-1))/(3×3×5×9)
3×3 = 9:
(-2 (-1))/(9×5×9)
9×5 = 45:
(-2 (-1))/(45×9)
45×9 = 405:
(-2 (-1))/405
-2 (-1) = 2:
