What is Formulas and functions in Excel make use of cell .?

Formulas and functions in Excel are powerful tools that allow users to perform calculations and data manipulation directly within cells. A formula is an expression that operates on values in cells, starting with an equal sign, while functions are predefined calculations, such as SUM or AVERAGE, that can be used within formulas for convenience and efficiency. Both enable dynamic updates, meaning if the data in the referenced cells changes, the results of the formulas and functions automatically reflect those changes. This makes Excel a robust tool for data analysis and financial modeling.
