Question 807469: If 10 books can be arranged in a row on a bookshelf and 4 are computer science and 6 are math books. In how many ways can they be arranged so that the math books are on the left? I know the 4 cs books are 4! and the math is 6!, I just was not sure if you add or multiple them, or if I'm on the wrong track all together.

For every one of the 6! ways to arrange the math books, there are 4! ways to arrange the CS books. Multiply.
