What is a Spreadsheet?
A spreadsheet is the computer equivalent of a paper ledger sheet.
It consists of a grid made from columns and rows.
It is an environment that can make number manipulation easy and somewhat effortless.
Types of Spreadsheets:
Manual – creating a worksheet on a ledger
or columnar paper using a pencil/pen,
calculator, and eraser.
Electronic – A computer-generated
spreadsheet that makes the basic tasks
much easier.
Spreadsheets are made up of :
columns – identified with alphabetic headings
rows - identified with numeric headings
and their intersections are called
cells
(Cell references: B4, A20)
In each cell there may be the following types of data:
text (labels)
number data (constants)
formulas (mathematical equations that do all the work)
Formulas ALWAYS begin with an = sign. This “tells” Excel that a calculation will need to be performed.
Reference cells, NOT the numbers in them!
There are two ways to enter information into a cell:
1. Type directly into the cell.
Click on a cell, and type in the data (numbers or text) and press Enter.
2. Type into the formula bar.
Click on a cell, and then click in the formula bar. Now type the data into the bar and press Enter.

launcher in the bottom-right corner of a group. When you

Cells
The combination of a column coordinate and a
row coordinate make up a cell address.
For example, the cell located in the upper-left
corner of the worksheet is cell A1, meaning column A, row 1.
Formula Bar
If the Formula bar is turned on, the cell
address of the cell you are in displays
in the Name box which is located on the left side of
the Formula bar. Cell entries display on the right side
of the Formula bar. Note: The current cell address displays
on the left side of the Formula bar.
Status Bar
Display information such as the sum, average, minimum, and maximum value of selected numbers. You can change what displays on the Status bar by right-clicking on the Status bar and selecting the options you want from the Customize Status Bar menu. You click a menu item to select it.
