Seven math books and three literature books are on a shelf, how many ways can they be arranged if the books are kept together

This is the theory of combination.

The number of books in the shelf are:

math books=7

literature books=3

the number of ways they can be rearranged is given by the combination of the respective books on the shelf which is:

7C3

=210

thus we conclude that there are 210 ways in which the books can be enjoyed.
