The Word Spreadsheet
The term spreadsheet was derived from a large piece of paper that accountants used for business finances. The accountant would spread information like costs, payments, taxes, income, etc out on a single, big, oversized sheet of paper to get a complete financial overview.
Some examples of spreadsheet usage:
Spreadsheets act like a calculator by automatically doing calculations.
Spreadsheets are used for tracking personal investments, budgeting, invoices, inventory tracking, statistical analysis, numerical modeling, address books, telephone books, printing labels, etc.
Spreadsheets are used in almost every profession to calculate, graph, analyze and store information.
Spreadsheets are used for What-if calculations. Change one number in a spreadsheet and all the calculations in a large spreadsheet will re-calculate, will automatically change.

The fourth toolbar down is the Formula Toolbar. The Formula Toolbar contains the Name Box drop-down menu and a long white box called the Input Line.

The Spreadsheet Itself
The rest of the window contains the spreadsheet. The spreadsheet is divided into rows that have a number at the left of each row and divided into columns with letters at the top of each column.
A cell is the fundamental element of a worksheet. This is where things are added and where things are seen. A cell address in a spreadsheet identifies the location of the cell in the spreadsheet. A cell address is a combination of the column letter and the row number of a cell, such as A2 or B16.etc. When identifying a cell by its address, the column letter is always listed first followed by the row number. The cell address of the example below is A5.
- Click on the A1 cell (The cell at the very top left of the spreadsheet).
- Notice the heavy black border around the A1 cell. The heavy black border indicates that A1 is the active cell. (A is at the top of the first column and 1 is on the first row. Both are highlighted. The highlighting also indicates that A1 is the active cell.)
Type Hello World and press Enter.
The active cell is now A2. (The words “Hello World” are in A1.)
- When you type something in a cell and press Enter, what you typed is seen in that cell and the cell below becomes the next active cell.
Click on A1 again.
Press the Delete key. (The “Delete Contents” window appears.)
- Check the Delete all box then click OK. (“Hello World” is deleted from A1)
- Click cell A1. > Type the number -9999.129 > Press Enter. (The cursor moves to cell A2)
- Right-click cell A1. (A small menu appears) > click Format cells. (The “Format cells” window appears)
