Using a Spreadsheet

A Spreadsheet is used to record, organise and manipulate numerical data. A spreadsheet consists of cells formed by the intersection of rows, which are named numerically and columns which are named alphabetically.

This example uses information from a Personal Shopping List to create and use a spreadsheet.

Creating a Spreadsheet

Shopping List
2 jars of Vegemite, 3 bottle of Coke, 1 loaf of bread, 2 cartons of milk, a packet of frozen beans and a tube of toothpaste.

  • Open a spreadsheet document.
  • Notice that a spreadsheet is made up of rows and columns forming cells which are named A1, A2, B4 etc.



  • To enter data, click in a cell and type. The data does not appear in the cell, but in the entry bar, which is above the cells. Press the Return key or click on the green tick (the Accept button) and the information in the entry bar will be placed in the spreadsheet. Click on the red cross (Cancel button) to remove the information from the entry bar.



  • To start our personal shopping list, click in cell A1 and type the word Item and press Return.
  • The word will appear in the selected cell and cell A2 will be highlighted. (If you press Enter on the numeric keypad, the data will appear in the cell but A1 will remain highlighted.)
  • To move to another cell, either click in the chosen cell or press Return to move down the column or Tab to move across a Row.
  • For our example, leave cell A2 empty (press return) and type the name of each item to be included in a personal shopping list in Column A and press Return after each item.



  • Some of the words may extend into column B as they are too long to fit in column A. To change the width of a column, either choose Column Width from the Format menu and enter a larger/smaller point size or move the cursor to the vertical line between the column names. It will change to a double sided arrow. Move the arrows to change the width of the column.



  • In Cell B1 type the word Amount, in C1 Cost and in D1 Total.
  • Add all the data in column B and C.



  • To change the numbers in column C to dollars and cents, highlight all the amounts in column C, then Select Number from the Format menu.



  • Click on the Currency button, then OK.



  • The amounts will have a $ dollar sign.

 

Making Calculations

Spreadsheets are capable of performing calculations.provided they are given instructions. Let's give the instruction to find how much it will cost to buy the items listed. eg How much will it cost to buy 3 bottles of Coke?

  • Select Cell D3 and type the equals sign = which will appear in the Entry Bar.
  • Click once in cell B3, type the multiplication symbol *, then click once in cell C3. The Entry Bar should now have the formula =B3*C3. Click in the Accept box and the correct answer should appear in cell D3.



    = instructs the spreadsheet to perform a calculation
    * means multiply
    / means divide
    The formula above gives the instruction - multiply the contents of cell B3 by the contents of cell C3.
  • To copy the formula to the other cells in the column, click in cell D3 then drag down to cell D8 to highlight the cells in column D which need to be filled.
  • Select Fill Down from the Calculate menu and the answers should appear in the cells. While the cells are highlighted, select Currency from the Number menu to change the answers to dollars and cents.



To find the Grand Total of all purchases, the formula used will need to include more than two cells. The formula will take the form
=sum(1st cell * last cell)

  • Click in the cell D10 (where the total will appear) and type
    =sum(
  • Then click in the first cell to be included, D3, and drag to the last cell to be included, D8 and type the closing bracket. Click on the Accept button (or press Return).



  • While cell D10 is highlighted, select Numbers from the Calculate menu and change to Currency.

    Not much change from $20!
