2.  Software program capable of performing many calculations, functions, graphs  Arranged in rows (by number) and columns (letters)  Intersection of a row and column is the cell reference, e.g., B4

3.  Sum a row or column of numbers  Method 1: use the Auto sum  Method 2: key using formula bar:  Notice the “range” inside the brackets

4.  =E9-E8 Subtract the value in E8 from E9  =G3*F2 Multiplies G3 by F2  =K3/C4 Divides K3 by C4  =AVERAGE(E1:E8) Finds the average value in this range  =MIN(E1:E8) Finds the lowest value in this range  =MAX(E1:E8) Finds the largest value in this range  =COUNT(E1:E8) Reports the quantity of entries in this range

5.  Useful to show increase in value  Example 1: =B4+B4*0.05 (fair)  Example 2: =B4*1.05 (better)  Example 3: =B4*$K$1 (best)  Where $K$1 contains % you can change!

6. Control~Shows formula view Widen ColumnsHold left mouse key over line to move Merge Cells Format NumbersRight-click, Format

7.  Create a formula and “drag” lower right corner to apply across or down (click the pic!)

8.  =IF(B9>-1,"Profit","Loss")  Show the word "profit" if the value is zero or higher, otherwise shows the word "Loss"

9.  By default copied or filled formulas reflect related cells  What if we need % of one total?  $ signs in cells signify the cell is constant

10.  By default column A is the x-axis and B, C, D, etc. are for values (Y-axes)  Use the graph icon  Name the series to create proper legends  Excel graphs are drab … spice them up!

11.  3D Column Graph Better!
