Formulas and Constants

Constant is entries that does not change. It maybe a number, such as a grade on an exam, or it

may be descriptive text (name).

Formula is combination of numeric constants, cellreferences, arithmetic operators, and/or functions.

Always begins with an equal sign

=(B3+B4+B5/5)

=AVERAGE(B3:B7)

Definitions General format it is the default format for numeric

entries and displays a number according to the way itwas originally entered.

Number format displays a number with or without the1000 separator and with any number of decimal places.

Negative numbers can be displayed with parenthesesand/ or can be shown in red.

Scientific format which displays a number as adecimal fraction followed by a whole number exponent of

10; for example the number 12345 would appear as1.2345E+04. The exponent, +04 in the example, is thenumber of places the decimal point is moved to the left.Very small numbers have negative exponents.

Relative references means it would changefrequently.

Absolute reference means it would not

change frequently, its permanent. For example:$C$11 in cell.

Pointingits more accurate to just pointing tothe cell that you needed to process it. You candirectly click in the cell that will contain theformula and type an equal sign to beginentering the formula, and click in the cell you

wants to reference. 19

Relative versus Absolute Addresses

The distinction between relative and anabsolute reference is: a cell reference

changes during a copy operation (relative)versus one that does not (absolute). Considerthe PMT function as it appears in cell B6:

21


21/30

PMT Calculates loan payment amounts

PMT function requires three arguments(the interest rate per period, the number ofperiods, and the amount of the loan).

= PMT (0.09/12, 36,-14999)

Interest rate per period (annual rate divided by12)

Number of periods (3 year 12 months/year)

Amount of loan (as a negative amount)

22

In class activity 11


22/30

FV (Future Value The interest rate is also called the rate of return,

the number of periods, and the periodicinvestment.

Ex: If you plan to contribute $3000 a year to an

IRA, expect earning 7% annually, and that youwill be contributing for 40 years (begincontributing from25~65). And the amount ofmoney would be $589,905.

Amount at retirement = FV (Rate of return, Term,Periodic payment)

Computed value becomes $598905

7%

40 years $3 000
