  # Q3 Party Planner: Formula

13. Dig the Data

This demo uses Google Sheets. This works the same as in Excel except where noted in the steps below.

## Introduction

You have now created and formatted your basic spreadsheet. One of the really useful functions of a spreadsheet is its ability to do calculations. It can do much more than a calculator can do if you know how to create a formula. All formulas start with an equal sign. Let's calculate how many people will be coming to your party!

## STEPS for Using a Formula to Add a Column

Using the directions above, complete the following:

Step 1 - Create an addition formula to add up the total invitees
start with the = symbol, followed by SUM and an open parens (then drag
down across the cells and a closed parens ) and hit enter.

Your formula should look like =SUM(B3:B7) where the : indicates including
all the cells between B3 and B7.
Step 2 - Create an addition formula to find total attending in the next column in a similar way.
Step 3 - Make sure that your formulas work
Step 4 - Google Sheets: Select the View menu and Show formulas. Then take a screenshot.
Microsoft Excel: Put your mouse in one of the Totaled cells and view the formulas in the fx space directly above the sheet and take a screenshot of that.

Step 5 - Save your screen shot with one of the formulas showing
Step 7 - Check with your teacher to see how they want you to submit or share this document.

Note: after you enter the formula, click on Return or Enter, and the total will appear instead of the formula. Microsoft Excel
