WHAT IS A SPREADSHEET
PART 2
What is a spreadsheet
Spreadsheets do the same kind of tasks as calculators. However,
spreadsheets can show you the result of more than one calculation at a
time. Here are examples of how a spreadsheet might be used:



To calculate the average rainfall over a month in different parts of
the country
To compare the rise or fall in the birth rate in different cou nties
To find the total marks gained by all pupils in a range of subjects.
There are two parts to a spreadsheet:
1.
2.
The spreadsheet application created by a software company.
This software is either bought in a shop or sold as part of an IT
system.
The data entered by you into the spreadsheet.
Let’s learn the language of spreadsheets by looking at part of a
spreadsheet you will use later. It is about the costs of buying
equipment for a fitness centre.
A spreadsheet is a grid made from:
 rows numbered 1, 2, 3, 4, ….(Remember the above is only part of a
spreadsheet.)
 columns headed A, B, C, D, E, F, G ……….

WHAT IS A SPREADSHEET
Where a row and column intersect is called a cell. Each cell gets its
name from the row and column which form it.
For example, ‘Exercise bike’ is in A2. Cell D3 holds £1060.00. Cell
B1 holds ‘Number’. The letter always comes first in a cell name.
There is an online animation available entitled ‘What is a
spreadsheet’.
Questions 1
In the screenshot above,
1. What is showing in cell D2? A1? B3?
2. In what cell does £530.00 appear?
Here is the same spreadsheet but this time with cell B2 s elected. The
selected cell is always surrounded by a black box.
B2 holds the number 3.

WHAT IS A SPREADSHEET
The formula bar
When a cell is selected, the name of the cell and its contents are
shown elsewhere on the spreadsheet. Find where this happens by
comparing the screenshot on the previous page with the one above.
This area of the spreadsheet is called the formula bar.
You now know that a spreadsheet cell can hold text, usually called a
label. It can also hold a value that may take different forms –
numbers, money, date, etc.
A cell can hold one other type of content – a formula. A formula is
just a way of setting out a calculation that has to be done. Let’s look at
how formulas are used in spreadsheets.
Cell D2 is selected in this screenshot.
Look at the formula bar and you will see that this time, it actually holds
a formula. This formula says ‘Multiply the contents of B2 by the
contents of C2’. Therefore, the calculation is 3 x 495.
What you see in cell D2 is the result of carrying out the formula. The
cell holds the formula but displays the result.
Formulas can use +, -, * (for multiplication), / (for division), and other
mathematical functions.
There is an online animation available entitled ‘Formula
Bar’

EDITING A SPREADSHEET
PART 3
Editing a spreadsheet
You will need the file Gym Equipment for this part.
 Double click on the icon for Gym Equipment.
The computer recognises it as an AppleWorks file. It launches
AppleWorks and then loads the data in Gym Equipment into the
AppleWorks layout.
What you see on the screen should look something like the screenshot
below. You may already recognise some of the words in the menu bar
and icons in the tool bar.
The Black Ace Fitness Centre needs to update its equipment. This
spreadsheet helps the manager to decide what he can or cannot afford
to buy.

EDITING A SPREADSHEET
Adding a formula
You should have discovered by now that cells D6 to D9 contain a
formula which means:
multiply together the values in column B and column C
in this row and put the result in column D in the same
row.
The correct form of this formula needs to be entered for the roller
glides in D11.
Questions 4
1. What is the formula that should be entered in D11? Check
your answer in Part 5: SAQ Answers before moving on.
 Click on D11. This is where the formula will be held.
 Type an equals sign (=) in the formula bar above.

The computer now knows you are going to enter a formula.
 Enter the formula = B11 * C11 into the formula bar. (See above.)
 Click OK in the drop-down window. The formula result – £58.90 –
now appears in D11.

EDITING A SPREADSHEET
Let’s try entering another formula.
You are going to enter into D12 a formula that will add up the values in
D6 to D11. This will tell the manager the total cost for all the
equipment.
The computer will enter 0 for the empty cell D10.
 Click on D12. This tells the computer where to put the formula that
you will enter.
 Type an equals sign (=) in the formula bar.
 In the formula bar, enter D6+D7+d8+d9+D10+D11. (Note that the
use of capitals is not necessary.)
 Click OK. The result - £5,784.90 - should appear in D12.
Formatting a spreadsheet
You will have noticed that column A is not wide enough for ‘ Rowing
machine’.
You can change column width in exactly the same way as you did in
the section on databases.
Changing cell width
 Move the pointer from the column heading A towards B.
 When it changes to a black cross, click and drag the mouse gently
to the right.
Column A will now be wider. You can drag it back a little if necessary.
There is an online animation available entitled ‘Changing
a column width’.
Changing font and style is also part of formatting a document.
Font is the way the letters and numbers are formed.
Style is whether the words are written in plain or bold text, italics
or underlined.

Changing style
You are going to change the style of the words in cells A1 and A3.
First you have to highlight the words that will get the change of style.
 Click on cell A3. ‘Planned Purchase of Gym Equipment’ appears in
the formula bar above.
 Move the pointer to the tool bar and click on one of these style
buttons.
B is for bold, I for italics and U for underline.
 Click the mouse button on another part of the screen
to see the effect.
Try each style in turn. If you lose the highlight by mistake, the
computer will not know what text to change. If this happens, start
again at the beginning.
 Save and print out all the changes you have made to the spreadsheet.
There is an online animation available entitled ‘Changing
Style’.
These processes in AppleWorks Spreadsheet are exactly the same as
in the AppleWorks Database. You will also find that they are the same
in word processing in the next section. This is because the same
software company wrote all three applications.
Let’s use the menus for these tasks this time.
Saving a file
 Click on File in the menu bar.
 Select Save from the drop-down menu that appears. Your file will
now be updated to contain all the changes you have made.
