# Overview

It is inevitable to apply functions and expressions to calculate some data during use of reports. Writing expressions are supported in many places in UReport2. Most typically, we can change the type of the cell to be “expression” and then we can enter the corresponding expression and function in the expression editor below. Moreover, we can also use expressions in conditions, picture sources and QR code data sources etc. in UReport2. The complex statements and reports can only be prepared after we learn and master expressions provided in UReport2.
