All Power Apps Math & Statistical Functions (With Examples)

Math and statistical functions are among the most used functions in Power Apps. Fortunately, they are also some of the easiest functions to learn. Doing math inside of Power Apps has a lot in common with Microsoft Excel. Many of the core functions like SUM and COUNT are exactly the same. In this article I will list all the Power Apps math & statistical functions and show examples of how to use them.
