Question

Please Evaluate 8(12+7-9)

Answer 1

Distribute 8 to all of your numbers inside of the parentheses first, and then add and subtract all of your numbers together to get 80.
8(12+7-9)
96+56-72
152-72
80

OR...

Do what's inside the parentheses first, which equals 10. Then multiply that by 8 and get the same answer. 80. 

Answer 2

You distribute 8 into all the numbers which would be 8×12, 8×7, and 8×9. So the answer would be 96+56-72. Hope that helps.
