What is a spreadsheet?

A spreadsheet is a two dimensional calculator that uses a system of interconnected cells where each cell has an address. Each cell address has two parts: (1) a column reference indicated with a letter, and (2) a row reference indicated with a number. When referring to a cell the column part of the reference ALWAYS comes first.

Why use spreadsheets?

Spreadsheets permit efficient and accurate calculations. The degree to which you create an accurate and efficient spreadsheet is correlated to your understanding of how to use spreadsheet references and predefined spreadsheet functions.
