THE BASIC SHEET

THE LAYOUT

COLUMNS [vertical]: Labelled from A to ZZ

ROWS [horizontal]: Labelled 1 – 60,000 [approx]

A CELL MAY CONTAIN: Numeric data – numbers Alphanumeric data – letters & numbers.

A special form is “Titles” A “formula” – that is, a pre-programmed

calculation based on other cells. Note that the “result” of the calculation is displayed.

A “function” – a different form of formula – again “result” is displayed.

Examples

CREATING A FORMULA

Is created in the Cell where the result is wanted

Uses Symbols:To start formula: =Arithmetic: +, -, * [multiply], / [divide]Contextual: Brackets – ( )

Can use contents of other Cells or numbers entered in the formula itself

AN EXAMPLE

Cell I.D.Formula

DisplayedResult

MULTIPLE USE A formula can be

copied to be used multiple times: Highlight original

Cell – copy Highlight all

required Cells – paste

Pastes copies to all highlighted cells

MULTIPLE USE [2]

MULTIPLE USE [3]

MULTIPLE USE [4]

The copying changes the formula in each row relative to the row it’s in

This means the formula need only be created once

This happens automatically – if the formula is to be applied multiple times but is to apply to a specific cell, then a special command is needed

FORMULA USING A SPECIFIC CELL

Using our previous example but:

Price to be in US$ Amount wanted in CAD$

Note in the two following illustrations that the “row” reference changes as the formula is copied but the exchange rate reference remains constant

The difference is that $ sign precedes the Column [E] and the Row [2]. This means always Column E and always Row 2.

FORMULA USING A SPECIFIC CELL

FORMULA USING A SPECIFIC CELL

Note also that B3*C3 is shown as (B3*C3) Arithmetic operations in brackets are carried out

first when formulas are calculated After that other arithmetic operations are carried

out. In this example the brackets are not strictly

necessary as the same result is achieved with and without them. BUT this is not always true. It is good practice to use them
