# Mathematical Functions*This article explains how you can add mathematical expressions to rule conditions. It also gives you an example knowledge map so you can explore mathematical expressions in the Rainbird Studio.*

**Mathematical functions are transformative expressions** that change or transform numbers/number instances, and are used in rules.

This article will demonstrate what the different functions do by themselves, but multiple functions can be combined in expressions, and the values generated by the functions can also be used in further expressions. You will need to use brackets if combining multiple functions, to ensure Rainbird calculates a value correctly.
