it means “factorial.”
4! is the same as saying “four factorial.”
the way it works is really simple.
you take the number, and every whole, positive, number less than it, and you multiply them together.
so 4! would be:
4 x3 x2 x1 = 24
and 5! would be:
5 x 4 x 3 x 2 x 1 = 120.

! stands for “factorial”. 4! reads “four factorial”.
It means to multiply all the numbers up to the number before the factorial. Like, 4! means 1 X 2 X 3 X4 (= 24).

It is the factorial symbol which means you multiply the number by every number one lower than the one before it until you get to 1.
x!=(x)(x-1)(x-2)(x-3)……(1)
Therefore 4!= 4x3x2x1=24
In your example above, 4!/4 it would be 24/4=6

“!” stands for factorial
so 4!
means 4X3X2X1 which =’s 24
so
(4!+4) – 4/4= (24+4) – 1 = 28-1 = 27
