What does the functions button allow users to do?

The functions button in a spreadsheet program allows users to add functions into the spreadsheet, which are pre-defined formulas designed to perform specific calculations or operations on the data. Functions can automate processes, making complex calculations simpler and more efficient.

For instance, using functions like SUM, AVERAGE, or COUNT can help synthesize large volumes of data quickly without requiring the user to manually input calculations. By clicking the functions button, users can easily access a library of available functions and insert them into their worksheets, helping to streamline data analysis tasks.

This capability is fundamental to leveraging the power of spreadsheets, allowing users to manipulate and analyze data more effectively. Understanding how to use functions is crucial for maximizing the utility of spreadsheet tools.
