• [ Note to trainer : For detailed help in customizing this template, see the very last slide. Also, look for additional lesson text in the notes pane of some slides.]
• Here’s what’s going on in our example: Imagine that Excel is open and you’re looking at the &amp;quot;Entertainment&amp;quot; section of a budget for household expenses. Cell C6 in the worksheet is empty; the amount spent for CDs (compact discs) in February hasn&apos;t been entered yet.
• [ Note to trainer : Steps—given in either numbered or bulleted lists—are always shown in yellow text.]
• So if you ever wonder later on how you got the result you did, you can look in the formula bar to see the formula.
• Note : You can use more than one math operator in a single formula. This course covers only single-operator formulas, but you should know that if there’s more than one operator, formulas are not just calculated from left to right. The rules of operator precedence and two example formulas are on the Quick Reference Card available at the end of this training presentation.
• Clicking the AutoSum button uses the SUM function to add up the values. To save time, use the SUM function whenever you have more than a few values to add up, so that you don’t have to type the formula.
• The next two lessons explain cell references and functions in more detail.
• Notes: After you drag the fill handle over cell C7, the formula =SUM(C3:C6) will be visible in the formula bar near the top of the worksheet whenever cell C7 is selected. You can drag the fill handle to copy formulas only into cells that are next to each other, either horizontally or vertically. The AutoFill Options button requires no action and disappears when you next make an entry in any cell.
• [ Note to trainer : With Excel 2003 installed on your computer, you can click the link in the slide to go to an online practice. In the practice, you can work through each of these tasks in Excel, with instructions to guide you. Important : If you don’t have Excel 2003, you won’t be able to access the practice instructions.]
• By default, Excel uses a reference style called A1, which refers to columns with letters and to rows with numbers. The letters and numbers are called row headings and column headings. The table shows how to refer to cells by using the column letter followed by the row number. The rest of the lesson shows you what happens if the value in a cell changes after a total is calculated.
• Note: You can revise a formula in a selected cell by typing either in the cell or in the formula bar.
• What else is going on as you follow these steps: Instead of typing cell references, you click the cells that you want to include in the formula. As you click to select cells C4 and C6, a colored marquee surrounds each cell and then disappears when you press ENTER. The formula =SUM(C4,C6) appears in the formula bar near the top of the worksheet whenever cell C9 is selected. The parentheses are required to separate the arguments from the function. The comma, which is also required, separates the arguments.
• Relative references In the first lesson about entertainment expenses, you could copy the January formula to add up February expenses because the references automatically changed as they were copied from column to column. As the example illustrated here shows, when the formula =C4*\$D\$9 is copied from row to row, the relative cell references change from C4 to C5 to C6. Absolute references As the picture shows, when the formula =C4*\$D\$9 is copied from row to row, the absolute cell reference remains as \$D\$9.
• An example of a mixed reference: \$A1 is an absolute reference to column A and a relative reference to row 1.
• References are relative by default. Typing the dollar signs, as shown at number 2 in the picture, changes the reference type to absolute.
• [ Note to trainer : With Excel 2003 installed on your computer, you can click the link in the slide to go to an online practice. In the practice, you can work through each of these tasks in Excel, with instructions to guide you. Important : If you don’t have Excel 2003, you won’t be able to access the practice instructions.]
• The formula =MAX(F3:F6) appears in the formula bar near the top of the worksheet.
• As always, the formula =MIN(F3:F6) would appear in the formula bar. And instead of using the AutoSum button, you could also type the formula directly into a cell.
• You should know that cells with error values such as #NAME? may display a color triangle. If you click the cell, an error button appears to give you some error correction options. How to use that button is not covered in this course.
• Details about using these functions goes beyond the scope of this training presentation, but this and the following slide describe how to get to functions in the Insert Function dialog box.
• Click Help on this function at the bottom of the dialog box to find out more about any function.
• [ Note to trainer : With Excel 2003 installed on your computer, you can click the link in the slide to go to an online practice. In the practice, you can work through each of these tasks in Excel, with instructions to guide you. Important : If you don’t have Excel 2003, you won’t be able to access the practice instructions.]

• 2. Course contents
• Overview: Simple calculations in Excel
• Lesson 1: Get started
• Lesson 2: Use cell references
• Lesson 3: Simplify formulas by using functions
Enter formulas Each lesson includes a list of suggested tasks and a set of test questions.
• 3.
• After you try Excel, you’ll never go back to a calculator. In this course you’ll learn how to add, divide, multiply, and subtract by typing formulas into Excel worksheets.
Overview: Simple calculations in Excel Enter formulas You’ll also learn how to use simple formulas that automatically update their results when values change.
• 4. Course goals
• Do math by typing simple formulas to add, divide, multiply, and subtract.
• Use cell references in formulas, so that Excel can automatically update results when values change or when you copy formulas.
• Use functions (prewritten formulas) to add up values, calculate averages, and find the smallest or largest value in a range of values.
Enter formulas
• 5. Lesson 1 Get started
• 6. Get started
• In this lesson, you’ll learn how to use Excel as your calculator by typing simple formulas into cells.
• You’ll also learn how to total all the values in a column with a formula that updates its results if values change later on.
Enter formulas A budget worksheet needs an amount in cell C6.
• 7. Begin with an equal sign
• Two CDs purchased in February cost \$12.99 and \$16.99. The total of these two values is the CD expense for the month.
• You do math in Excel by typing simple formulas into cells. Excel formulas always begin with an equal sign (=).
Enter formulas Typing a formula in a worksheet
• 8. Begin with an equal sign
• Here’s how to add 12.99 and 16.99 in cell C6:
Enter formulas Typing a formula in a worksheet
• Type the formula =12.99+16.99 . The plus sign (+) is a math operator that tells Excel to add the values.
• Press ENTER to display the formula result, 29.98.
• 9. Begin with an equal sign
• Here’s how to add 12.99 and 16.99 in cell C6:
Enter formulas Typing a formula in a worksheet
• The formula appears in the formula bar near the top of the worksheet whenever you select cell C6.
• 10. Use other math operators
• To do more than add, you can use other math operators as you type formulas into worksheet cells.
• You start each formula with an equal sign and then use a minus sign (-) to subtract, an asterisk (*) to multiply, and a forward slash (/) to divide.
Enter formulas Excel uses familiar signs to build formulas. Math operators Add (+) =10+5 Subtract (-) =10-5 Multiply (*) =10*5 Divide (/) =10/5
• 11. Total all the values in a column
• To add up the total of expenses for January, as shown in the picture, you wouldn’t have to type all those values again.
• Instead, you could use a prewritten formula, called a function .
Enter formulas Using the AutoSum button to total column values
• 12. Total all the values in a column
• To get your January total:
Enter formulas
• A colored marquee surrounds the cells in the formula, and the formula appears in cell B7.
Using the AutoSum button to total column values
• Select cell B7, and then click the AutoSum button on the Standard toolbar. The AutoSum button adds up all the values in a range of cells.
• 13. Total all the values in a column
• To get your January total:
Enter formulas Using the AutoSum button to total column values
• Press ENTER. This displays the SUM function result 95.94 in cell B7.
• Select cell B7 to display the formula =SUM(B3:B6) in the formula bar.
• 14. Total all the values in a column
• B3:B6 is the information, called the argument , that tells the SUM function what to add.
Enter formulas Using the AutoSum button to total column values By using a cell reference (B3:B6) instead of the values in those cells, Excel can automatically update results if values change later on.
• 15. Total all the values in a column
• The colon (:) in B3:B6 indicates a cell range in column B, cells 3 through 6. The parentheses are required to separate the argument from the function.
Enter formulas Using the AutoSum button to total column values
• 16. Copy a formula instead of creating a new one
• Sometimes it’s easier to copy formulas than to create new ones. In this example, you’ll see how to copy the January formula and use it to add up the February expenses.
• Start by selecting cell B7, which contains the January formula. Then position the mouse pointer over the lower-right corner of the cell until the black cross (+) appears.
Enter formulas Copying a formula
• 17. Copy a formula instead of creating a new one
• Next:
Enter formulas Copying a formula
• Drag the fill handle over cell C7 and then release it. The February total 126.93 appears in cell C7.
• After the formula is copied, the AutoFill Options button appears to give you some formatting options.
• 18. Suggestions for practice
• Create a formula to add.
• Create formulas for other arithmetic.
• Add up a column of numbers.
• Copy a formula.
• Add up a row of numbers.
Enter formulas Online practice (requires Excel 2003)
• 19. Test 1, question 1
• What do you type into an empty cell to start a formula? (Pick one answer.)

• 21. Test 1, question 2
• What is a function? (Pick one answer.)
Enter formulas
• A prewritten formula.
• A math operator.
• 22. Test 1, question 2: Answer
• A prewritten formula.
Enter formulas Functions are prewritten formulas, such as SUM, that save time.
• 23. Test 1, question 3
• A formula result is in cell C6. You wonder how you got the result. To see the formula, you do which of the following? (Pick one answer.)
Enter formulas
• Select cell C6, and then press CTRL+SHIFT.
• Select cell C6, and then press F5.
• Select cell C6.
• 24. Test 1, question 3: Answer
• Select cell C6.
Enter formulas It’s that simple. The formula is visible in the formula bar near the top of the worksheet whenever you select cell C6. Or you can double-click cell C6 to see the formula in cell C6. Then press ENTER to see the formula result again in the cell.
• 25. Lesson 2 Use cell references
• 26. Use cell references
• Cell references identify individual cells or cell ranges in a worksheet. They tell Excel where to look for values to use in a formula.
• In this lesson you’ll see why Excel can automatically update the results of formulas that use cell references, and how cell references work when you copy formulas.
Enter formulas Cell references Cell references Refer to values in A10 the cell in column A and row 10 A10,A20 cell A10 and cell A20 A10:A20 the range of cells in column A and rows 10 through 20 B15:E15 the range of cells in row 15 and columns B through E A10:E20 the range of cells in columns A through E and rows 10 through 20
• 27. Update formula results
• Suppose it turned out that the 11.97 in cell C4 for video rentals in February was incorrect. A rental of 3.99 was left out.
• To add 3.99 to 11.97, you would select cell C4 and type this formula into the cell:
Enter formulas Excel can automatically update totals to include changed values. =11.97+3.99
• 28. Update formula results
• As the picture shows, when the value in cell C4 changes, Excel automatically updates the February total in cell C7 from 126.93 to 130.92.
Enter formulas Excel can automatically update totals to include changed values. Excel can do this because the original formula =SUM(C3:C6) in cell C7 contains cell references.
• 29. Update formula results
• If you had entered 11.97 and other specific values into a formula in cell C7, Excel would not be able to update the total.
Enter formulas Excel can automatically update totals to include changed values. You’d have to change 11.97 to 15.96 not only in cell C4, but in the formula in cell C7 as well.
• 30. Other ways to enter cell references
• You can type cell references directly into cells, or you can enter cell references by clicking cells, which avoids typing errors.
• In the first lesson you saw how to use the SUM function to add all the values in a column. You could also use the SUM function to add just a few values in a column, by selecting the cell references to include.
Enter formulas Selecting cell references to add a few values
• 31. Other ways to enter cell references
• Imagine that you want to know the combined cost for video rentals and CDs in February.
Enter formulas Selecting cell references to add a few values You don’t need to store the total, so you could enter the formula into an empty cell and delete it later. The example uses cell C9.
• 32. Other ways to enter cell references
• Here’s how to enter the formula:
Enter formulas Selecting cell references to add a few values
• Type the equal sign, type SUM , and type an opening parenthesis in cell C9.
• Click cell C4, then type a comma in cell C9.
• 33. Other ways to enter cell references
• Here’s how to enter the formula:
Enter formulas Selecting cell references to add a few values
• Click cell C6. Then type a closing parenthesis in cell C9.
• Press ENTER to display the formula result of 45.94. The arguments C4 and C6 tell the SUM function what values to calculate with.
• 34. Reference types
• Now that you’ve learned more about using cell references, it’s time to talk about the different types of references that are used in formulas: absolute , relative , and mixed .
Enter formulas Relative and absolute cell references
• 35. Reference types
• Here are the details:
Enter formulas Relative and absolute cell references
• Relative references automatically change as they are copied down a column or across a row.
• Absolute references are fixed; they don’t change if you copy a formula from one cell to another. Absolute references have dollar signs (\$) like this: \$D\$9.
• 36. Reference types
• A mixed cell reference has either an absolute column and a relative row, or an absolute row and a relative column.
Enter formulas Relative and absolute cell references As a mixed reference is copied from one cell to another, the absolute reference stays the same but the relative reference changes.
• 37. Use an absolute cell reference
• Say you receive a package of entertainment coupons offering a 7 percent discount for video rentals. How much could you save in a month by using the coupons?
• To figure it out, you could create a formula to multiply those February expenses by 7 percent, using absolute references to refer to cells that you don’t want to change as the formula is copied.
Enter formulas Using an absolute cell reference
• 38. Use an absolute cell reference
• Type the discount rate of 0.07 in the empty cell D9, and then type a formula in cell D4, starting with =C4* . Then enter a dollar sign ( \$ ) and D to make an absolute reference to column D, and \$9 to make an absolute reference to row 9.
Enter formulas Using an absolute cell reference Your formula will multiply the value in cell C4 by the value in cell D9.
• 39. Use an absolute cell reference
• Next, copy the formula from cell D4 to D5 by using the fill handle .
Enter formulas Using an absolute cell reference As the formula is copied, the relative cell reference changes from C4 to C5, while the absolute reference to the discount in D9 does not change—it remains \$D\$9 in each row it is copied to.
• 40. Use an absolute cell reference
• So, to recap the relative and absolute cell references in the example:
Enter formulas Using an absolute cell reference
• Relative cell references change from row to row.
• The absolute cell reference always refers to cell D9.
• Cell D9 contains the value for the 7 percent discount.
• 41. Suggestions for practice
• Type cell references in a formula.
• Select cell references in a formula.
• Use an absolute reference in a formula.
• Change values and totals.
Enter formulas Online practice (requires Excel 2003)
• 42. Test 2, question 1
• What is an absolute cell reference? (Pick one answer.)
Enter formulas
• The cell reference automatically changes when the formula is copied down a column or across a row.
• The cell reference is fixed.
• The cell reference uses the A1 reference style.
• 43. Test 2, question 1: Answer
• The cell reference is fixed.
Enter formulas Absolute cell references won’t change if you copy a formula from one cell to another.
• 44. Test 2, question 2
• Which cell reference refers to a range of cells in column B, rows 3 through 6? (Pick one answer.)
Enter formulas
• (B3:B6)
• (B3,B6)
• 45. Test 2, question 2: Answer
• (B3:B6)
Enter formulas The colon indicates a range of cells starting at B3 and including B4, B5, and B6.
• 46. Test 2, question 3
• If you copy the formula =C4*\$D\$9 from cell C4 to cell C5, what will the formula be in cell C5? (Pick one answer.)
Enter formulas
• =C5*\$D\$9
• =C4*\$D\$
• =C5*\$E\$10
• 47. Test 2, question 3: Answer
• =C5*\$D\$9
Enter formulas As the formula is copied, the relative cell reference, C4, changes to C5. The absolute cell reference, \$D\$9, does not change; it remains the same in each row it is copied to.
• 48. Lesson 3 Simplify formulas by using functions
• 49. Simplify formulas by using functions
• SUM is just one of the many Excel functions . These prewritten formulas simplify the process of entering calculations, making it easy and quick to create formulas that might be difficult to build for yourself.
• In this lesson you’ll see how to speed up tasks with a few easy functions.
Enter formulas Function names express long formulas quickly. Function Calculates AVERAGE an average MAX the largest number MIN the smallest number
• 50. Find an average
• You could use the AVERAGE function to find the average cost of all entertainment for January and February:
Enter formulas Using the AVERAGE function
• Click in cell D7, click the arrow on the AutoSum button , and then click Average in the list.
• Press ENTER to display the result in cell D7.
• 51. Find an average
• The formula =AVERAGE(B7:C7) appears in the formula bar near the top of the worksheet.
Enter formulas Using the AVERAGE function You could also type this formula directly into the cell.
• 52. Find the largest or smallest value
• The MAX function finds the largest number in a range of numbers, and the MIN function finds the smallest number in a range.
Enter formulas Using the MAX function
• 53. Find the largest or smallest value
• Here’s a formula to find the largest value in the set:
Enter formulas Using the MAX function
• Click in cell F7, click the arrow on the AutoSum button, and then click Max in the list.
• Press ENTER to display the result in F7.
The largest value is 131.95.
• 54. Find the largest or smallest value
• Finding the smallest value in the range is a similar process: You’d click Min in the list and press ENTER.
Enter formulas Using the MAX function The smallest value would be 131.75.
• 55. Print formulas
• You can print formulas to put up on your bulletin board to remind you how to create them.
Enter formulas Formulas displayed on the worksheet
• On the Tools menu, point to Formula Auditing , and then click Formula Auditing Mode .
• Print as you usually would.
• 56. What’s that funny thing in my worksheet?
• Sometimes Excel can’t calculate a formula because the formula contains an error.
• If that happens, you’ll see an error value instead of a result in a cell.
Enter formulas The ##### error value
• 57. What’s that funny thing in my worksheet?
• Here are three common error values:
Enter formulas The ##### error value ##### The column is not wide enough to display the contents of the cell. Increase column width, shrink the contents to fit the column, or apply a different number format. #REF! A cell reference is not valid. Cells may have been deleted or pasted over.
• 58. What’s that funny thing in my worksheet?
• Here are three common error values:
Enter formulas The ##### error value #NAME? You may have misspelled a function name or used a name that Excel does not recognize.
• 59. Find more functions
• Excel offers many other useful functions, such as date and time functions and functions you can use to manipulate text.
• You can see these other functions by clicking More Functions in the AutoSum list. This opens the Insert Function dialog box, which helps you search for a function and provides another way to enter formulas.
Enter formulas The Insert Function dialog box
• 60. Find more functions
• When the dialog box is open, you can type what you want to do in the Search for a function box, or select a category and then scroll through the list of functions.
