Introduction to Microsoft Office Excel

Microsoft Excel is a computer program used to create electronic spreadsheets. Within Excel,users can organize data, create charts, and perform calculations. MS Excel is a convenient

program because it allows the user to create large spreadsheets, reference information from

other spreadsheets, and it allows for better storage and modification of information. Excel

operates like other Microsoft (MS) Office programs and has many of the same functions and

shortcuts of other MS programs.

Overview of the Excel Screen

Microsoft Excel consists of workbooks. Within each

workbook, there is an infinite number of worksheets.

Each worksheet contains columns and rows.

Where a column and a row intersect is called the

cell. For example, cell B6 is located where column B

and row 6 meet. You enter your data into the cells

on the worksheet.

The tabs at the bottom of the screen represent

different worksheets within a workbook. You can

use the scrolling buttons on the left to bring other

worksheets into view.

●

To change the view of your work so that it is page by page.

●

To insert Headers and Footers to your work.

●

To add comments about a specific cell for future reference.

Entering Formulas

●

When entering numerical data, you can command Excel to do any mathematical function.

●

Start each formula with an equal sign (=). To enter the same formulas for a range of cells, use thecolon sign “:”

Addition Formulas

●

To add cells together use the “+” sign.

●

To sum up a series of cells, highlight the cells, then click the auto sum button. The answer will

appear at the bottom of the highlighted box.

Subtraction Formulas

●

To subtract cells, use the “-” sign.
