In its most basic form, a spreadsheet is a table of data. For many users, it is an electronic replacement for calculators, ledgers and erasers. Spreadsheets allow users to make simple data changes and not have to recalculate formulas ? that process can be set to automatically update the spreadsheet when existing data is changed or new data is entered..

1. Two very useful features of spreadsheets are:
1. Ability to replicate formulas for each row (e.g., student) and each column (e.g., assignment, lunch money, etc.) without having to retype the formula or enter the column or row of numbers in a calculator.
2. Ability to predict (and manipulate) a total project cost, year-end earnings, final course grades, total field trip cost, etc. by changing individual numbers in the chart.
For example, what will happen to my ant farm projects final cost if each group gets two containers of live ants but only half a bushel of soil? (Sound like a story problem? It is! Just type in the new numbers and watch the bottom line change.)

3. 2. Components of a Spreadsheet
4. Columns
Are vertical areas labeled by letters at the top.
To highlight an entire column, click on the letter at the top of the column.
In Excel, the number of columns is limited to 256. In Open Office, the maximum amount of columns is 245.In Open Office, the maximum amount of columns is 245.
5. Rows
Are horizontal areas labeled by numbers
To highlight an entire row, click on the number at the start of the row.
In Excel, each spreadsheet can have a maximum of 65,536 rows. In both Excel and Open Office, each spreadsheet can have a maximum of 65,536 rows.In both Excel and Open Office, each spreadsheet can have a maximum of 65,536 rows.
6. Cell
Intersection of a column and a row
Labeled by joining the column letter followed by the row number
May contain numbers, words or a combination of the two (e.g. An address)
Cell C8 has 127 as its contents and the name box displays the cell's name.

7. Cell from another sheet
You may call a cell from another sheet and display it on the current one.
In Excel, the syntax is: =sheetname!cellname To display a cell from another sheet:
either type in the name of the cell and sheet or
type = then click on the sheet's tab, click on the desired cell then press enter.

9. A formula is an equation that performs operations on worksheet data. Formulas can perform mathematical operations, such as addition and multiplication, or they can compare worksheet values or join text. Formulas can refer to other cells on the same worksheet, cells on other sheets in the same workbook, or cells on sheets in other workbooks. The following example adds 25 to the value in cell B4 and then divides the result by the sum of the values in cells D5, E5, and F5.
Functions are predefined formulas that perform calculations by using specific values, called arguments, in a particular order, or structure. For example, the SUM function adds values or ranges of cells
