# Math Help - Distribution Issue?

1. ## Distribution Issue?

Again with the O of O (I thought I had it licked)

2^3 -10[4 -(-2 +18)3]

8 -10[4 +2 -18 +3]

8 -10[6 -15]

8 -10(-9)

8 + 90

98

But that's incorrect. The book says the answer is 448, so I'm a long way off. The only think I can think of is that it's a distribution problem. Any help is greatly appreciated.

2. In going to the second step, you had -(-2+18)3 turn into 2-18+3. The 3 was multiplying (parentheses mean multiplication, unless used as part of a function label) the (-2+18), but then it was added. So you need to multiply the result of what was in the parentheses by 3.

3. Your mistake is in the first step.

4-(-2+18)3 = 4-(-16)*3, multiplication before subtraction, so
that makes 4+48, which should lead you to the correct answer.
