How to use Google Sheets functions (e.g., SUM, AVERAGE, VLOOKUP) to perform calculations?

To use Google Sheets functions like SUM, AVERAGE, VLOOKUP, and others to perform calculations, follow these steps:

1. Open a Google Sheets document and enter the data on which you want to perform calculations.
2. Select the cell where you want the result of the calculation to appear.
3. Use the "=" sign to start a formula in that cell.
4. Type the function name, followed by an open parenthesis "(".
5. Depending on the function, enter the required arguments separated by commas. For example, for the SUM function, enter the range of cells you want to sum up.
6. Close the parentheses ")" and press Enter to calculate the result.

Here are examples of using various functions:

• SUM: To find the sum of a range of cells (e.g. A1 to A10), enter "=SUM(A1:A10)".
• AVERAGE: To calculate the average of a range of cells, use "=AVERAGE(A1:A10)".
• VLOOKUP: To search for a value in the leftmost column of a range and return a corresponding value from a specified column, use "=VLOOKUP(A1, B1:C10, 2, FALSE)". Here, A1 is the value to search, B1:C10 is the range to search, 2 indicates the column from which to return the value, and FALSE means an exact match is required.

Explore Google Sheets' extensive library of functions to perform various calculations by typing the function name into a cell and using the autocomplete feature for guidance. Additionally, you can access the "Functions" tab in the toolbar for categorized lists of functions.
