  Introduction: Data Analysis Expressions (DAX) is a powerful formula and query language used in Power BI for creating calculated columns, measures, and advanced calculations. It provides a flexible and efficient way to manipulate and aggregate data to derive valuable insights. In this article, we will explore 22 powerful DAX formulas and functions that beginners can leverage to perform complex data manipulations and aggregations within Power BI. 1.
