How to Perform Calculations in Excel

Microsoft Office Excel is a spreadsheet program. It is used by many people for computation purposes. Microsoft Office Excel 2003 comprises many functions that can be used to solve hundreds of mathematical problems.

You get your results instantly. There is a tool called auto fill that you will fall in love with as it will make your work so easy. Performing calculations in Excel is so easy as you will come to realize.

Creating an Excel Workbook

A workbook is a file that you are going to create in Excel. This file will carry your data. To do this go to:-

  • Start
  • All Programs
  • Microsoft Office
  • Microsoft Office Excel

When the Excel window opens, at the top (title bar) you will see the name Book 1 or something like that. You are supposed to save your workbook immediately so as to give it a name before you start entering your data. Go to:-

  • File
  • Save as
  • Type the file name of your workbook and select the location where you want to save it.
  • Then click on save.

Entering Data in MS Excel

Before you even learn how to compute using excel, you can decide to go through an introduction to Microsoft Office Excel 2003. The main title or heading of your work should be typed on cell A1 while the subheadings should be typed in row two. Data is entered on the individual cells. By clicking on a cell, you make it active and ready to accept any input. While entering your data, you can use the arrow keys for navigation; they are more efficient rather than using the mouse. Remember to often keep saving your work to avoid loss of data if the power goes off.

This can be done by going to File > Save or simply pressing the Ctrl + S keys on your keyboard.

Formatting Your Excel Document

If you are familiar with word document formatting, then this one will be almost the same. Highlight your heading (simply click on cell A1) and go to Format > Cells > Font. The Font dialog box appears where you are going to select the font, font style, size, underline style, font colour and special effects that you want to apply to your document. Format the rest of your document the same way.
