(edited 11 months ago)
The numbers are far too big for a calculator to cope with. Instead, think about what factorial means and whether something might cancel

Isn't ! just a variable like x, so it's 100!/294!, so the ! cancel out to give 100/294, and you simplify by dividing top and bottom by 2, giving 50/147
It's not a variable, no. It's an operation. It's telling you to multiply the number before ! by every integer below it, down to 1. e.g. 3!=3x2x1=6

100! = 100x99x98x97...
98! is 98x97x96...
therefore 100! / 98! gives you 100x99
so its 9900/3!

100! = 100 x 99 x 98 x 97 x . . .
= 100 x 99 x 98!

oh okay, so 1650 as it is 100*99/3!, as the rest of the operation i.e. 98*97*96*.... gets cancelled out by 98! on the denominator, so 9900/6 = 1650
