Back to: COMPUTER SCIENCE JSS3

 

Welcome to Class !!

We are eager to have you join us !!

In today’s Computer Science class, We will be discussing Spreadsheets. We hope you enjoy the class!

 

 

 

Spreadsheets are like lined paper with columns. The sheet itself comprises of columns (vertical) and rows (horizontal) which are in turn, made up of cells. A spreadsheet is the computer equivalent of a paper ledger sheet.

 

 

A spreadsheet can be defined as the combination of rows and columns used in performing arithmetic calculations. It was first constructed in 1979 and has developed into one of the most widely used software products during the 1980s. It is widely used in a diverse range of disciplines such as mathematics, engineering, science, medicine, the arts, social science, accounting and education.

                                                         

 

SPREADSHEET PACKAGE

An electronic spreadsheet is an application package used mostly in accounting, statistics, financial and inventory control.

Spreadsheet package is a software that allows the use of numerical data and thereby performing automatic calculations on numbers contained in a table. Spreadsheet packages are used to handle accounting problems, financial analysis, budgeting, charting and graphing, scientific applications, inventory, statistical data, etc.

In a spreadsheet, as you enter the numbers, the computer puts them on to the screen in neat columns. You can tell the program to compute the totals, subtotals, percentages and show them on the screen faster than your eye can blink.
