Target Number #20- Make 248 -

Using the numbers 1, 2, 3, 3, 4, and 6 (in any order), can you write a mathematical expression (e.g. (6*3)*(3+1)-(4/2)) with a result equal to 248?

You may only use 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. 6 and 4 to make 64).
3. You may only use a number as many times as it appears above.
