# Unlocking the Power of Functions in Spreadsheets

## What is a function in spreadsheets?

a) A built-in formula

b) A custom calculation

c) A manual operation

d) An automated task

## Answer:

a) A built-in formula

**Explanation:** In spreadsheets, a built-in formula that you can use to perform a calculation on the data in your worksheet is called a function. Functions are pre-defined formulas that can be used to perform various calculations, such as summing numbers, finding averages, counting cells, and more.

Functions are designed to simplify complex calculations and automate repetitive tasks. They take input values, called arguments, and return a result based on those arguments. For example, the SUM function adds up a range of numbers, while the AVERAGE function calculates the average of a range of numbers.

To use a function, you need to enter it in a cell and provide the necessary arguments. The function will then calculate the result based on the specified arguments and display it in the cell.
