TOPIC: SPREADSHEET I

DEFINITION OF SPREADSHEET: A spreadsheet is a collection of cells organized into rows and columns where data is stored and manipulated. The spreadsheet is known as a worksheet. A spreadsheet begins with row number one and column A. A cell is a space in a worksheet formed by the intersection of a row and a column. Each cell can contain a number, text or formula. A cell can also reference another cell in the same worksheet, the same workbook or a different workbook. Each cell has an address called Cell Reference e.g. A1, B3, C7 etc. combination of more than one sheet is referred to as workbook. The worksheets can accept thousands of rows of data and columns in the form of fields. Active Cell is recognized by heavy border surrounding. It is the cell that is currently worked upon.

CONTENT OF SPREADSHEET

When you are setting out a spreadsheet, you have to enter values, labels and formulas.
• VALUES: Values are those numbers you already know before starting the spreadsheet operation. These values are inserted into cells of the spreadsheet.
• LABELS: Labels are words you enter to explain the values. You would not just enter a list of numbers without explanation. Putting labels next to each of the numbers makes it easier to check it through.
• FORMULA: Formulas are the mathematical equations you insert into the cells. Formulas are commands that instruct the computer on what to do.
