# Built-In Function: Mathematical Operations

Learn how to perform different mathematical operations using built-in functions.

## We'll cover the following

Built-in functions in a programming language are very useful and can be a huge advantage in day-to-day tasks since we don’t have to write them ourselves . Python has a lot of functions built into it that are always available. Similarly, PowerShell has access to .Net classes that brings some useful functions as well. In this lesson, we are going to cover various built-in functions provided by PowerShell and Python.

## Basic Mathematical Operations

We’ll come across various day-to-day tasks where it is required to perform basic mathematical operations. Let’s look into them one at a time.
