LESSON 3 Working with Functions, Formulas, and Charts

2 Functions  A predefined formula that used the values in the cells you select to calculate its answer Sum—adds the values in a range of cells Average—averages the values of a range of cells Count—counts the cells containing numbers in a range of cells

3 Functions  A predefined formula that used the values in the cells you select to calculate its answer Max—finds the highest value in a range of cells Min—finds the lowest value in a range of cells Round—adjust a value displaying to a certain number of digits

4 Functions  =SUM(A1:B10) This function/formula will add the values of the range of cells listed in the argument

5 Functions  =SUM(A1:A40,C1:C40) Adds the cells A1 through A40 and C1 through C40

6 Functions  =B2/SUM(C3:C5) Takes the value in B2 and divides it by the sum of the values in C3 through C5

7 Functions  =ROUND(SUM(B12:B23),2) Totals the values in the range B12 to B23 and rounds that to two decimal points

8 Functions  =MAX(C10:C100) Displays the highest value in the range of C10 to C100

9 Functions  IF Functions =IF(condition,x,y) The user can tell Excel to perform one of two different calculations based on whether your data matches a certain condition (the condition will be either True or False) (x will be the result if the condition is True) (y will be the result if the condition is False)

10 Functions  IF Functions Use equals (=), greater than (>), less than (<), greater than or equal to (>=), less than or equal to (<=) as conditional operators in the condition statement.

11 Functions  IF Functions =IF(B2>500000,B2*10%,B2*3%) If b2 is greater than , (condition) then value in B2 times 10 percent, (True) otherwise value in B2 times 3 percent (False)

12 Functions  =SUMIF(G2:G10,”<=500”) Computer will add the values in G2 to G10 Only if the value is less than or equal to 500

13 Functions  =SUMIF(I10:I25,”x”,J10:J25) Sum range J10 to J25 if X is in the range I10 to I25
