Another Interview Puzzle Computers

Dave Brillhart posted a few logic puzzles that came from job interviews. They are quite interesting and I encourage you to try them.

Here is another puzzle from a job interview that my cousin received. It's not as hard as Dave's but not as many people get it as you would think, especially in the confines of a job interview.

Using the integers 1, 3, 4 and 6, and using only the four basic arithmetic operators + - * / (add, subtract, multiply, divide), create an equation that equals 24. Each number is used only once. The operators can be used as many times as you want. There is no "trick" to this, there really is a basic equation that produces 24.

I will post the answer in a few days.

Update: You must produce 24 exactly, no integer math. Like I said, no tricks.
