factorial, in mathematics, the product of all positive integers less than or equal to a given positive integer and denoted by that integer and an exclamation point. Thus, factorial seven is written 7!, meaning 1 × 2 × 3 × 4 × 5 × 6 × 7. Factorial zero is defined as equal to 1.

How do you calculate a factorial?
To find the factorial of a number, multiply the number with the factorial value of the previous number. For example, to know the value of 6! multiply 120 (the factorial of 5) by 6, and get 720.
What is a factorial and how do you calculate it?
A factorial is a function that multiplies a number by every number below it. For example 5!= 5*4*3*2*1=120. The function is used, among other things, to find the number of way “n” objects can be arranged.

The factorial of a number is very important in probability .
How do you solve 5 Factorials?
To find 5 factorial, or 5!, simply use the formula; that is, multiply all the integers together from 5 down to 1. When we use the formula to find 5!, we get 120. So, 5! = 120.

How is factorial symbol written?
The factorial function is a mathematical formula represented by an exclamation mark “!”.
What is the factorial of negative numbers?
The factorials of real negative integers have their imaginary part equal to zero, thus are real numbers. Similarly, the factorials of imaginary numbers are complex numbers. The moduli of the complex factorials of real negative numbers, and imaginary numbers are equal to their respective real positive number factorials.
Can you multiply factorials?
Factorials, denoted by a.You can also multiply factorials by hand. The easiest way to do it is to calculate each factorial individually, and then multiply their products together. You can also use certain rules of factorials to pull out common factors, which can simplify the multiplication process.
What type of math uses Factorials?
The value of 0! is 1, according to the convention for an empty product. The factorial operation is encountered in many areas of mathematics, notably in combinatorics, algebra, and mathematical analysis. Its most basic use counts the possible distinct sequences – the permutations – of n distinct objects: there are n!.
What is the logic of factorial?
Factorial of a non-negative integer, is multiplication of all integers smaller than or equal to n. For example factorial of 6 is 6*5*4*3*2*1 which is 720.
How do you write factorial in Python?

Who invented factorial in mathematics?
Christian Kramp
One of the most basic concepts of permutations and combinations is the use of factorial notation. Using the concept of factorials, many complicated things are made simpler. The use of ! was started by Christian Kramp in 1808.
