3. Must begin with an equals (=) sign Contain mathematical operators
Formula Basics
Formulas are used to perform mathematical operations and arrive at a calculated result
Must begin with an equals (=) sign
Contain mathematical operators
Used to automate calculations that were once done manually

4. Creating a Formula
Rather than typing a cell address, use an alternative method that involves minimal typing
Pointing uses the mouse or arrow keys to select the cell directly when creating a formula

5. Copy Formulas with Fill Handle
Use the fill handle, a small black square in the bottom right corner of a selected cell, to copy formulas
Provides a clear-cut alternative method for copying the contents of a cell
Can be used to duplicate formulas 5

6. Relative vs. Absolute Addressing
Relative cell references change relative to the direction in which the formula is copied
Absolute cell references are exact; they do not change when a formula is copied
Indicated by dollar ($) signs in front of the column letter and row number
Most often used when the value need not change, such as a sales tax percentage.
Use the F4 key to toggle between relative and absolute cell referencing 6

7. Using Absolute References7

8. Functions A predefined formula that can be selected from a list
Already has the formula information; just requires cell references
Do not replace all formulas
Take values, perform operations, and return results
SUM is the most commonly used function
represented by a sigma ()
Adds values within a specified range
Syntax refers to the grammatical structure of a formula
Must adhere to stated structure of formula
Arguments are values ─ used as input and returned as output
Function Wizard automates entering the function formulas 8

9. Inserting a Function 9

10. Inserting a Function 10

11. Automates the SUM function Click the cell where you want the result
Using AutoSum ()
Automates the SUM function
Click the cell where you want the result
Click AutoSum button
Select the range of cells you want to sum
Press Enter to complete
An example of AutoSum,
=Sum(C4:C10) represents sum of all the cells in the cell range C4 to C10 11

12. Basic Statistical Functions
Perform a variety of calculations to aide in decision making process
AVERAGE calculates the average of a range of numbers
MIN calculates the minimum value in a range
MAX calculates the maximum value in a range
COUNT counts the number of values within a range
MEDIAN finds the midpoint value in a range 12

13. Efficiently handle time-consuming procedures
Date Functions
Efficiently handle time-consuming procedures
Help analyze data related to the passing of time
TODAY function places the current date in the selected cell =TODAY()
Updates when file is opened again
NOW function displays current date and time, side by side 13

14. Logical and Lookup Functions
Logical functions help in decision making
Lookup functions are very useful for looking up data entered in a specific range of cells
Example: Well suited well for tax tables
Searches for a value based on a cell reference
Two types: VLOOKUP and HLOOKUP
VLOOKUP arranges data vertically
HLOOKUP arranges data horizontally 14

15. Working with Logical Functions
A comparison operator is a symbol that indicates the relationship between two values 15

16. Working with Logical Functions16

17. Used to determine whether a condition has been met
IF Function
Used to determine whether a condition has been met
Has three arguments:
=IF(condition,value_if_true,value_if_false)
a condition tested to determine if it is true or false
the resulting value if the condition is true
the resulting value if the condition is false
When the condition is met, the formula performs one task; when it is not met, the formula performs another task 17

18. Allows for lookup within a vertical table of information
VLOOKUP
Allows for lookup within a vertical table of information
Well suited for large tables of data, such as tax tables
Has three required arguments and one optional argument:
VLOOKUP(lookup_value,table_array,col_index_num,r ange_lookup)
a lookup value stored in a cell
a range of cells containing a lookup table
the number of the column within the lookup table that contains the value to return 18

19. The lookup value ─ value to look up in a reference table
VLOOKUP (continued)
The lookup value ─ value to look up in a reference table
The lookup table ─ a range of cells containing the reference table
A breakpoint ─ is the lowest numeric value for a category or series
The column index number ─ the column number in the lookup table that contains return values 19

20. Allows you to consider several alternatives
Financial Functions
Used for decisions involving payments, investments, interest rates, etc.
Allows you to consider several alternatives 20

21. Used to calculate loan payments Has three arguments:
PMT Function
Used to calculate loan payments
Has three arguments:
PMT(rate,nper,pv,fv,type)
the interest rate per period
the number of periods
the amount of the loan
Computes the associated payment on a loan 21

22. Used to determine the future value of an amount, such as an investment
FV Function
Used to determine the future value of an amount, such as an investment
Has three arguments:
FV(rate,nper,pmt,pv,type)
The interest rate (also called the rate of return)
The number of periods (how long you will pay into the investment)
The periodic investment (how much you will invest per year) 22

23. Using the PMT Function to Determine a Monthly Loan payment23
