106! / 104! is the same as 106*105*104! / 104!.

The 104! in the numerator and the denominator cancels out and you are left with:

106 * 105 = 11130

Take smaller numbers to prove this is good.

Take 5! / 3!

Using your calculator, you would get 20

Doing 5*4*3!/3! you get 5*4 = 20

Same answer.

You can use the calculator with MS Windows to do larger factorials, but it makes sense to simplify it first, as the other tutor did.
