Question

(7-5)!

Answer 1

2!

Answer 2

is it really? what does the"!" mean then?

Answer 3

The '!' means "factorial"

It is where you take a number and multiply it by every number smaller than itself...

e.g. 4! = 4 x 3 x 2 x 1

10! = 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

Etc...

So where we have

\[\large (7 - 5)!\]

That means
\[\large (2)!\]

so that means

\[\large 2! = 2 \times 1 = 2\]
