As I know, in mathematics, the factorial of n natural numbers is the result of multiplication of positive integers less than or equal to n. Factorial is written as n! and is called n factorial.

For example, 7! is worth 7 × 6 × 5 × 4 × 3 × 2 × 1 = 5040. The following is a list of factorial:

various ways used to facilitate this process, including the use of a calculating machine. among many calculating machines or can be called by the application, I will build a calculating machine using VB.Net programming language, reason, among others, language is relatively easy to understand and implement.

on interface design, users only need to enter the factorial value to be calculated, then this application will automatically calculate, and display the results directly.

on the programming side of the mathematical computation process is relatively easily understood and implemented.I hope this application can be useful and beneficial to readers. thank you:)
