Target Number #02- Make 278 -

Using the numbers 1, 2, 3, 4, 5, and 6 (in any order), can you write a mathematical expression (e.g. 6*5*(4+3)/(2-1)) with a result equal to 278?

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. 2, 6, 5 to make 265).
3. You may only use a number as many times as it appears above.
