The number of different ways that 8 computer operators can be seated in a row is the same as the number of permutations of 8 things taken 8 at a time. That is 8 factorial, which is 40,320.
Think of it this way... You have 8 choices for the first seat, 7 choices for the second seat, 6 choices for the third seat, and so on to 1 choice for the last seat. That is 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1, otherwise known as 8 factorial.
