+129840 DS...those "exclamation marks" are called "factorials"....in simple terms, n! = the product of the first "n" positive integers......for example:
3! = the product of the first three positive integers = 3x 2 x 1 = 6
4! = the product of the first four positive integeers = 4 x 3 x 2 x 1 = 24
......etc......
This is a very important idea in statistics and probability. It's used to "count" things.... (sets, arrangements of objects, etc.)
Hope that helps !!!
+118654 $$\left({\mathtt{6}}{!}{\mathtt{\,-\,}}{\mathtt{3}}{!}\right) = {\mathtt{714}}$$
((6! - 3!) - ((6 × 100) - ((6 ÷ 3) × 100))) / 100
(714 - (600 - (2 × 100))) / 100
(714 - (600 - 200)) / 100
(714 - 400) / 100
Except for the missing bracket, you are correct!
