The exclamation mark indicates the operation called "factorial".
'Factorial' is an operation carried out on a whole number. It means: The product
of this whole number with every whole number less that this one, down to ' 1 '.
Examples:
3-factorial = 3 ! = 3 x 2 x 1 = 6
5 ! = 5 x 4 x 3 x 2 x 1 = 120
6 ! = 6 x 5 x 4 x 3 x 2 x 1 = 720
(5 !) / (3 !) = (5 x 4 x 3 x 2 x 1) / (3 x 2 x 1) = (5 x 4) = 20

It is called factorial, and means to multiply all the numbers up to the specified integer. For example, 5! (read: 5 factorial) is equal to 1 x 2 x 3 x 4 x 5 = 120. This special operation is often used in combinatorics, statistics, probability. it also appears in calculus.

Not always - it depends on the context. There would be an exclamation point if it was being shouted or if it was being said in an exclamatory manner.
What do the calculator symbols mean?
The symbols on a calculator represent different mathematical operations. For example, the "+" symbol is used for addition, the "-" symbol for subtraction, the "x" symbol for multiplication, and the "/" symbol for division. Other symbols like "^" represent exponentiation, "√" for square root, and "π" for the mathematical constant pi. Understanding these symbols is crucial for performing accurate calculations on a calculator.
What does an exclamation point mean as a math symbol?
An exclamation mark stands for factorial. For instance, if the number is 7!, then that would be 7x6x5x4x3x2x1. =================================================== Factorial means you multiply the integer written by every integer below it until you reach 1. Oddly enough, 0! = 1. There is also a 'factorial' function for non-integral values, called the Gamma function.
