Instead of writing your own code for various kind of mathematical operations in c sharp, you just need to know some predefined static methods and constant fields in System.Math class. By studying this lesson, you will be able to write sophisticated code in c# for various types of math operations by using the robust predefined methods and fields.

### What is Math class in C#?

The Math class comes under System namespace, and it is used for trigonometric, logarithmic, and other common mathematical functions. This class makes mathematical operations easy for programmer and they donâ€™t need to write their own code for various kind of mathematical calculations. In the Math class, there are several useful and handy functions are built-in, which can be used easily.

Here, I am only collecting the most useful methods in Math class. For the complete list of functions in Math class, you can visit the docs.microsoft.com.
