The number of ways of the books can be arranged are illustrations of permutations.
- When the books are arranged in any order, the number of arrangements is 3628800
- When the mathematics book must not be together, the number of arrangements is 2903040
- When the novels must be together, and the chemistry books must be together, the number of arrangements is 17280
- When the mathematics books must be together, and the novels must not be together, the number of arrangements is 302400
The given parameters are:



<u />
<u>(a) The books in any order</u>
First, we calculate the total number of books



The number of arrangement is n!:
So, we have:


<u>(b) The mathematics book, not together</u>
There are 2 mathematics books.
If the mathematics books, must be together
The number of arrangements is:

Using the complement rule, we have:

This gives


<u>(c) The novels must be together and the chemistry books, together</u>
We have:


First, arrange the novels in:

Next, arrange the chemistry books in:

Now, the 5 chemistry books will be taken as 1; the novels will also be taken as 1.
Literally, the number of books now is:



So, the number of arrangements is:



<u>(d) The mathematics must be together and the chemistry books, not together</u>
We have:



First, arrange the mathematics in:

Literally, the number of chemistry and mathematics now is:



So, the number of arrangements of these books is:


Now, there are 7 spaces between the chemistry and mathematics books.
For the 3 novels not to be together, the number of arrangement is:

So, the total arrangement is:
