In this problem we will start by remembering the order of operations, and know that parenthesis come first.
Let's assume that our problem is 2w-8(-7w+9), because a term was missing, I am adding this plus sign.
Now we have -8 times something in parenthesis, so we will use the distributive property. This is done by taking -8 times the first term, -7w, and then times our second term, 9.
So now we have 2w+56w-72.
We combine like terms, and get 58w-72.
9 to the 12th power would be 9 * 9 * 9 * 9 * 9 * 9 * 9 * 9 * 9 which would equal 282 429 536 481
= 90 (9*10)
Eight 9s do not equal 100. 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 = 72

9+9 and 9+9+9+9+9

yes 9+ 9 9 9 9 + 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 +

It's 9*9*9*9*9*9*9*9*9 or 387,420,489
9 + (9/9) = 10 (99/9) - (9/9) = 10 [ (9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9) / 9 ] + (9/9) = 10
9+9+9+9+9+9+9=63
9 + 9 + 9 + 9 + 9 + 9 = 54
9 nine 9 9 9 9 9 9 9 9 9
4782969
9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 - 5678 = -5606
99 = 9*9*9*9*9*9*9*9*9 (nine lots of 9) = 387,420,489
