Spreadsheet:Introduction

Introduction
Just what exactly is a spreadsheet?

In general terms a spreadsheet is a way to organise and perform calculations on rows and columns of data (text, numbers and dates), plus provides tools to display this data graphically. A spreadsheet is organised as a grid, with Columns labelled A,B,C,D, etc and rows numbered 1,2,3,4,.... This allows us to reference "cells" using the column and row co-ordinates. So, the top left is A1, etc...

Spreadsheets also allow us to view our data in many ways. In the following example, the bar chart has been created to help us see patterns in the data.
