To answer this question, let's first try an easier question:

How any integers are greater than 3 but less than 10?

The answer is 6 and they are 4, 5, 6, 7, 8, and 9.

Yet, when we subtract 3 from 10, we get 7:  10 - 3 = 7. This is 1 more than the answer.

So, the number of integers greater than 87 and less than 321, we should subtract 87 from 321, and then subtract 1 from that answer:  (321 - 87) - 1  =  233!
