24

Create the number 24 using (all of) 1, 3, 4, and 6.
You may add, subtract, multiply, and divide. Parentheses are free. You can (and must) use each digit only once. Note that you may not glue digits together. (14 - 6) * 3 is not a solution. 1^3 * 4 * 6 is not a solution either (powers not allowed).
