Excel Using Formulas and Functions Microsoft Office 2010 Fundamentals 1

Computers/ICTVMHS Introduction 2  The real power of a spreadsheet program such as Excel is its ability to perform simple and complex calculations on worksheet data.  Using the commands located on the Formulas tab of the Ribbon, you can enter formulas to perform calculations or use predefined formulas, called functions. 22

Computers/ICTVMHS Entering Formulas 3  A formula is a set of instructions used to perform calculations on values in a worksheet and must begin with the equal sign ( = ).  An operator is a sign or symbol that indicates what calculation is to be performed.  Arithmetic operators are used for addition +, subtraction -, multiplication *, division /, and exponentiation. 33

Computers/ICTVMHS Entering Formulas (continued) 4  Constants are numbers entered directly into a formula that do not change.  Cell references identify the cells containing the values you want to use in the formula. The results will automatically be updated if the values in those cells change. 44

Computers/ICTVMHS Entering Formulas (continued) 5  The formula is displayed in the formula bar; the results are displayed in the cell. 55

Computers/ICTVMHS Entering Formulas (continued) 6  The order of operations is a specific sequence used to calculate the value of a formula, from left to right: 1. Exponentiation ( ^ ) 2. Multiplication ( * ) or division ( / ) 3. Addition ( + ) or subtraction ( - )  To change the order of operations, use parentheses to group expressions. 66

Computers/ICTVMHS Understanding Cell References and Copying Formulas 7  A relative reference means the reference to a cell changes in relation to the location of the formula. 77

Computers/ICTVMHS Understanding Cell References and Copying Formulas (continued) 8  An absolute reference is a permanent reference to a cell and does not change in relation to the location of the formula. 88

Computers/ICTVMHS Understanding Cell References and Copying Formulas (continued) 9  Auto Fill is a feature that you can use to automatically fill in worksheet data in any direction.  You can use it to copy data or formatting or quickly copy a formula by dragging the fill handle—a little black square in the lower-right corner of the selected cell. 99

Computers/ICTVMHS Using Functions 10  Built-in formulas, called functions, enable you to perform complex calculations easily.  A function must follow a set of established rules, called syntax, that specifies how the function must be entered.  Most functions require an argument, which refers to the text, numbers, or cell references on which the function is to be performed. 10

Computers/ICTVMHS Using Functions (continued) 11  Use the Sum function to quickly total a range without manually typing the formula. 11

Computers/ICTVMHS Using Functions (continued) 12  Click the Sum button arrow to display a menu of the most common statistical functions. 12

Computers/ICTVMHS Using Functions (continued) 13  Click the Insert Function button to open the Insert Function dialog box. 13

Computers/ICTVMHS Using Functions (continued) 14  Once you select a function in the Insert Function dialog box or from the Ribbon, Excel opens the Function Arguments dialog box. 14

Computers/ICTVMHS Reviewing and Editing Formulas 15  To display the formulas instead of the resulting values, click the Show Formulas button in the Formula Auditing group on the Formulas tab. 15
