A little puzzle

The problem is simple, you have four digits, namely 6, 4, 3 and 1 and all the arithmetic operators, i.e. addition, subtraction, multiplication and division at your hand. You also have braces, i.e. "(" and ")".

Now your job is to make the number 24 using each of these four digits only once. You can use any of the operators and the braces. For example, if you were asked to make 23, you would do it like this:

23 = (6*3)+4+1 or 23 = (6-1)*4+3

So, how about 24 ?
