🎈It means that it is a type of formula or expressions that are used for the analysis and calculations of data.


🎈You need to understand its basic syntax.


🎈DAX formulas are written in a similar way to Excel formulas, using functions, operators, and references to columns or measures in your data model. 


Ex: If you have a Sales table with columns Quantity and Unit Price.


🎈You want to create a calculated column that calculates the total sales for each row.


Total Sales = Sales[Quantity] * Sales[Unit Price]


Total Sales is the name of the calculated column, and the formula multiplies the Quantity and Unit Price columns.
