Introduction
Formulas in Google Sheets help you do math and other calculations automatically. Instead of calculating numbers by hand, formulas update results instantly when your data changes. This saves time and reduces mistakes.

When you need to calculate the average score of students and want it to change if scores change
When you want to multiply prices by quantities to get total costs without typing each result
When you want to subtract discounts from prices and see the final price automatically
