Target Number #07- Make 178 -

Share this page on:
Puzzle Image Using the numbers 6, 6, 7, 7, 8, and 8 (in any order), can you write a mathematical expression (e.g. (6*6*7)-(8/8)+7) with a result equal to 178?

You may use any of the four BASIC math operations (addition, subtraction, multiplication, division) as well as parenthesis. Some additional rules:

1. You are not required to use all six numbers.
2. You may NOT join numbers (e.g. 8 and 7 to make 87).
3. You may only use a number as many times as it appears above.

Do you have a suggestion for this puzzle (e.g. something that should be mentioned/clarified in the question or solution, bug, typo, etc.)?
