  • Slide 2
  • Microsoft Excel is an electronic spreadsheet program. You may have heard the terms "spreadsheet" and "worksheet". People generally use them interchangeably. To remain consistent with Microsoft and other publishers the term worksheet refers to the row-and-column matrix sheet on which you work upon and the term spreadsheet refers to this type of computer application. In addition, the term workbook will refer to the book of pages that is the standard Excel document. The workbook can contain worksheets, chart sheets, or macro modules.
  • Slide 3
  • Spreadsheet A spreadsheet is the computer equivalent of a paper ledger sheet. It consists of a grid made from columns and rows. It is an environment that can make number manipulation easy and somewhat painless.
  • Slide 4
  • Spreadsheets are made up of columns rows and their intersections are called cells In each cell there may be the following types of data text (labels) number data (constants) formulas (mathematical equations that do all the work)
  • Slide 5
  • Columns In a spreadsheet the COLUMN is defined as the vertical space that is going up and down the window. Letters are used to designate each COLUMN'S location In the above diagram the COLUMN labeled C is highlighted.
  • Slide 6
  • Rows In a spreadsheet the ROW is defined as the horizontal space that is going across the window. Numbers are used to designate each ROW'S location. In the above diagram the ROW labeled 4 is highlighted.
  • Slide 7
  • Cells In a spreadsheet the CELL is defined as the space where a specified row and column intersect. Each CELL is assigned a name according to its COLUMN letter and ROW number (the cell reference) In the above diagram the CELL labeled B6 is highlighted. When referencing a cell, you should put the column first and the row second.
  • Slide 8
  • Types of Data In a spreadsheet there are three basic types of data that can be entered: labels - (text with no numerical value) constants - (just a number -- constant value) formulas* - (a mathematical equation used to calculate) Data typesExamplesDescriptions LabelName or Wage or Days anything that is just text Constant5 or 3.75 or -7.4any number Formula=5+3 or = 8*5+3math equation
  • Slide 9
  • Labels Labels are text entries. They do not have a value associated with them. We typically use labels to identify what we are talking about. The labels are NOT for the computer but rather for US so we can clarify what we are doing. In our first example: the labels were computer ledger car loan interest # of payments
  • Slide 10
  • Constants Constants are entries that have a specific fixed value. If someone asks you how old you are, you would answer with a specific answer. Sure, other people will have different answers, but it is a fixed value for each person. In our first example: the constants were $12,000 9.6% 60
  • Slide 11
  • As you can see from these examples there may be different types of numbers. Sometimes constants are referring to dollars, sometimes referring to percentages, and other times referring to a number of items (in this case 60 months). These are typed into the computer with just the numbers and are changed to display their type of number by formatting (we will talk about this later). Again, we use constants to enter FIXED number data.
  • Slide 12
  • Formulas Formulas are entries that have an equation that calculates the value to display. We DO NOT type in the numbers we are looking for; we type in the equation. This equation will be updated upon the change or entry of any data that is referenced in the equation.

Column Letterworksheetcolumn header Formula Bar Located above the worksheet, this area displays the contents of the active cell. It can also be used for entering or editing data and formulas.

  • Entering Data in Excel Plan your spreadsheet - Before you start to type. Plan your spreadsheet Before you begin entering data into a spreadsheet it is a good idea to do a bit of planning before you begin to type. Points to consider: What is the purpose of the spreadsheet?spreadsheet What information needs to be included? What headings are needed to explain the information in the spreadsheet? What is the best layout for the information? in rows or columns?rows columns

  • How to Enter Data into a Spreadsheet Entering your data into a spreadsheet is always a three step process.dataspreadsheet These steps are: Click on the cell where you want the data to go.cell Type your data into the cell. Press the ENTER key on the keyboard or click on another cell with the mouse.
  • Slide 17
  • Speeding up data entry Many people use the mouse when moving around their spreadsheet. Using the mouse, though, is the slow way of doing anything on a computer. It's fine if you have only a small amount of data to enter or if you're not in a hurry. To speed up your data entry use the keyboard. Below is a list of keys that you can use when you want to quickly enter your data. Enter key: enters the data and moves the active cell highlight down to the next cell in the current column.active cell Tab key: enters the data and moves the active cell highlight to the next cell in the current row. Arrow keys: enters the data and moves the active cell highlight to the next cell in the direction of the specific arrow key pressed. For example, if the up arrow is pressed, the active cell highlight moves up to the next cell in the current column. Esc key: cancels the current data entry.
  • Slide 18
  • Entering Text and Constants Text is displayed in two areas. Text is displayed in the active cell within the workbook and it is also displayed in the formula bar. The formula bar is activated as soon as you begin typing in a cell. At the far left is the reference section, which will show the reference of the active cell.
  • Slide 19
  • In the example below, the highlighted numbers 5 and 6 in the formula bar can be removed by hitting the DELETE key on the keyboard and replaced with different numbers.formula bar
  • Slide 20
  • Editing Cells in Excel Change Complete Cell Contents Click on the cell, type over the existing entry, and press the ENTER key on the keyboard. Change Part of the Cell Contents Method 1 Click on the cell to make it the active cell.active cell Click on the data in the formula bar. Delete the part to be changed and type in the new data. Press the ENTER key. Method 2 Double click on the cell. Edit the part of the cell you want to change. Press the ENTER key.
  • Slide 21
  • Moving around the spreadsheet Home key: moves the active cell highlight to column A without changing rows. Ctrl + Home keys: moves the active cell highlight to cell A1. Ctrl + End keys: moves the active cell highlight to the last cell of the spreadsheet containing data. Ctrl + Down Arrow keys: moves the active cell highlight to the last row of the spreadsheet without changing columns. Ctrl + Up Arrow keys: moves the active cell highlight to the first row of the spreadsheet without changing columns. Ctrl + Page Down keys: moves the active cell highlight to the next sheet of the spreadsheet. Ctrl + Page Up keys: moves the active cell highlight to the previous sheet of the spreadsheet.

  • Formatting Three areas of formatting are available in Microsoft Excel: number formatting - using percent, comma, date, and currency formatting cell formatting text formatting
  • Slide 23
  • Excel Math Adding Numbers in Excel To add two or more numbers in Excel you need to create a formula. Two important points to remember about Excel formulas:formula formulas in Excel always begin with the equal sign ( = ) the equal sign always goes in the cell where you want the answer to go
  • Slide 24
  • Use Cell References in Formulas Even though you can use numbers directly in a formula, it is much better to use the references or addresses of the cells containing the numbers you want to add. If you use the cell references rather than the actual data, later, if you need to change the data in either cell, the results of the formula will update automatically without you having to rewrite the formula.cell references

  • Setting Up the Addition Formula As an example, lets create a formula in cell C1 that will add the contents of cell B1 from cell A1. Our formula: =A1 + B1 Our data: place t
