1. Introducing Formulas and Functions

2. 2 Working with Formulas and Functions Revise in cell  Double-click in the cell Revise in the Formula Bar  Single-click in the Formula Bar Edit directly in cell Edit in Formula Bar

3. 3 Using AutoSum Automatically sum the contents of a column or row A flashing marquee surrounds the range

4. 4 Creating and Modifying Formulas Entering formulas  Begin with the equals (=) sign (can also begin with + or -)  Type cell references or use Point Mode  Use cell and range references to automatically recalculate answers as data changes Type cell references... or...Use Point Mode Flashing marquee around the last cell reference used in formula

5. 5 Using Cell References in Formulas Relative Cell References  All formulas use relative cell references by default (can be changed)  Relative references automatically update when a formula is copied If the formula in cell E4 is B4*C4, when you copy it to cell E5 the new formula will be B5*C5

6. 6 Using Cell References in Formulas Relative  A1: Updated when formulas are copied or moved Absolute  $A$1: Always refer to the same cell Mixed  $A1 or A$1: Rows or columns update when copied or moved Use (F4) to change default relative reference to absolute reference

7. 7 Displaying Formulas Display Formulas  To have ALL cells display their formulas instead of results use Tools → Options → View tab

8. 8 Using Statistical Functions Functions: formulas used over and over, so they’ve been built into the program  400+ included with Excel  Functions use their own syntax  =SUM(A1:IV224)  =MIN(B17:Q29)  =AVERAGE(D54:G27)  =COUNT(B5:B9) Get help with functions by clicking the Insert Function button

9. 9 Using AutoCalculate Display the Sum, Minimum Value, Maximum Value, Count, or Average of values in the highlighted range Right-click to make the pop-up menu appear
