SPREAD SHEET SOFTWARE
A
spreadsheet package is used for performing calculations and drawing charts. When you open a
spreadsheet package the screen looks like a very large table similar to this:
The
table is divided into a number of boxes called Cells. You can type information into each cell.
Going across the table are many Rows each of which is
identified by a number. Going down the table are many Columns
each of which is identified by a letter.
Each
cell is identified by a unique name called a Cell
Reference. The cell reference is formed by writing down the letter of
the column that the cell is in followed by the number of the row that it is in.
Groups
of joined cells are known as a Range. A range can be
described by writing down the cell references of the cells at the top left and
bottom right corners of the range with a colon to separate them.
You
can enter three different types of information into a cell. The three
types are :
- Numbers: Any number.
- Labels: Combinations of letters and numbers used as titles or labels to make the sheet clearer.
- Formulas: Used to carry out calculations with the numbers that are entered into the sheet.
- Formulas : Used to carry out calculations with the numbers that are entered into the sheet.
