IV-3.1

Performing Basic

CalculationsAfter completing this lesson, you will be able to:

Build formulas.

Copy formulas.

Edit formulas.

Use the SUM function and AutoSum.

Use the Insert Function feature.

Use Date functions.

Use absolute and relative cell references.

Use basic statistical functions.

Use numbered series and AutoFill.

With Microsoft Excel, it’s easy to perform common calculations. In addition to

adding, subtracting, multiplying, and dividing, you can calculate the total and

compute the average of a set of values. With basic calculations, you can figure

profit values from revenue and expenses, or you can compute an employee’s

wages from hours worked and pay rates. hese are !ust a few examples of the

calculations Excel can perform.

"t the "dventure Works resort, the reservations manager is preparing a report

on annual vacancy rates. o start, he finds the total number of nights that eachtype of room was occupied. hen he calculates the average number of rooms

occupied per night. #inally, he figures the occupancy rate for each type of

room. he results of these calculations will help him plan the upcoming season

and schedule cabin renovations for the time of year when demand is lowest.

"lso at "dventure Works, the accountant is calculating income generated from

e$uipment rentals for various activities. With those numbers, he can compute

the average income earned from each activity each month. he activities

coordinator will use these figures to plan her strategy for activities in the next

year.

In this lesson, you learn how to perform basic Excel calculations with formulas

and functions. %ou learn how to create and edit formulas, use mathematicaloperators, and use Excel’s built&in functions.

o complete the procedures in this lesson, you will need to use the files

'odging (sage.xls and "ctivity )entals.xls in the *art I+, 'esson- folder in

the omputer #undamentals *ractice folder located on your hard disk.

LESSON 3



IV-3.2 Computer Fundamentals

Building Formulas

" formula is the written expression of a calculation to be performed by Excel.

When you enter a formula into a cell, the formula is stored internally while the

calculated result appears in the cell.

" formula is a mathematical e$uation consisting of two elements/ operands and

mathematical operators. he operands identify the values to be used in the

calculation. "n operand can be a constant value, another formula, or a

reference to a cell or range of cells. Mathematical operators specify what

calculations are to be performed with the values.

o allow Excel to distinguish formulas from data, all formulas begin with an

e$ual sign 012 or a plus sign 032. o view a formula, click the cell containing

the formula. he formula will appear in the Formula bar.

%ou can use any of the following mathematical operators in a formula.

Operator Meaning

4 Exponentiation

5 Multiplication

6 7ivision

3 "ddition

& 8ubtraction

When a formula contains two or more operators, operations are not necessarily

performed in the order in which you read the formula9that is, left to right. he

order in which operations are performed is determined by operator priority, asdefined by the rules of mathematics. #or example, exponentiation is always

performed before any other operation. Multiplication and division are next on

the priority list, performed se$uentially from left to right. #inally, addition and

subtraction are performed, again from left to right. onsider the following

e$uation.

: 3 ; 5 < 6 - & = 1 >

#irst, four is multiplied by six, and the result is divided by three. wo is then

added to the result, and one is subtracted.

?perations contained within parentheses are completed before those outside

parentheses. %ou can override the standard operator priorities by using parentheses. hus, the following e$uation is calculated differently than the

previous one.

0: 3 ;2 5 < 6 0- & =2 1 =@

In this formula, two and four are added first, and the result is multiplied by six.

#inally, that result is divided by the result of three minus one.



Part IV: Lesson 3 Performing Basic Calculations IV-3.3

reating a formula is similar to entering text and numbers in cells. o begin,

you select the cell in which you want the formula to appear. hen you can use

one of two methods to create the formula.

In the first method, you type the formula, including cell addresses, constantvalues, and mathematical operators, directly into the cell. o mark the entry as

a formula, you start by typing an e$ual sign.

In the second method, you paste the references for a cell or range of cells in the

#ormula bar. %ou then complete the formula by typing any operators, constant

values, or parentheses.

"s you build a formula, it appears in the #ormula bar and the cell itself. When

you have completed the formula, the cell displays the result of the formula, and

the #ormula bar displays the formula itself.

he reservations manager at "dventure Works has tracked the number of

nights each type of room was occupied in each month for the last year. o

calculate occupancy rates, he must find the total number of nights occupied for

each month, divide that total by the number of rooms, and finally divide that

result by the number of nights in the month.

In this exercise, you open a worksheet and create basic formulas in the

worksheet.

Copying Formulas

%ou might often find that a similar formula is needed in several ad!acent cells.#or example, if you have a list of items and each item contributes to the total

income for one year, you might want to add the items to total the income for

that year. o total the income for consecutive years, you can create formulas to

sum the income for each year.

#ortunately, you can avoid entering formulas repeatedly and save a

considerable amount of time by copying a cell with a completed function and

pasting it into the destination cells. %ou can also use the #ill handle, which is

the small s$uare in the bottom&right corner of the active cell.

When you select a cell with a formula and drag the #ill handle, Excel changes

the cell references in the formula to match those of the column or row to which

it has been copied.

he reservations manager does not want to type the same formula over and

over to calculate the occupancy rate for each type of room for each month.

Instead, he copies his formulas to several locations.

Part IV: Lesson 3 Performing Basic Calculations IV-3.#

Using the SUM Function and AutoSum

?ne of the most common calculations performed in a worksheet is adding a

range of cells. %ou can add a range of cells by creating a formula that includeseach cell label separated by the addition 032 operator. "n easier way to achieve

the same result is to use the 8(M function.

" function is a predefined formula that performs a common or complex

calculation. " function consists of two components/ the function name and, in

most cases, an argument list . he argument list, which is enclosed in

parentheses, contains the data that the function re$uires to produce the result.

7epending on the function, an argument can be a constant value, a single&cell

reference, a range of cells, a range name, or even another function. When a

function contains multiple arguments, the arguments are separated by commas.

#or example, the 8(M function adds values or a range of cells. %ou enter the

range of cells as an argument to the function, and Excel calculates the total ofthe range. " typical 8(M function, totaling cells BC through B=, looks like

this.

18(M0BC/B=2

%ou will learn about other functions later in this lesson.

Excel’s AutoSum feature offers a shortcut for entering 8(M functions to total

ranges of cells. When you click the "uto8um button on the 8tandard toolbar,

Excel totals cells directly above or to the left of the cell containing the function.

he reservations manager learns that "uto8um can make it even easier for him

to complete his occupancy calculations. De can use "uto8um to calculate the

many totals he needs.

In this exercise, you use "uto8um to total a range of cells.

%o get around this problem,either alter the arguments to

inlude the full range of ells,

or selet onl# the range of

Using the nsert Function

%ou can enter a function into a cell !ust as you would enter any formula/ by

typing it directly in the cell or in the #ormula bar. he Insert #unction button

offers a third option. By accepting arguments and even additional functions, the

#unction "rguments dialog box helps you create formulas that contain

functions. In fact, the #unction "rguments dialog box is particularly useful

when a formula contains more than one function, such as a function within afunction. he Insert #unction dialog box lists each function. he #unction

"rguments dialog box lists each function’s arguments, a description of each

function and its arguments, the calculated result of each function, and the

overall formula.

"t "dventure Works, the accountant uses the Insert #unction feature to

calculate the annual income generated through the rental of various types of

sporting e$uipment.

In this exercise, you use the Insert #unction feature to enter functions in a

worksheet.

Using !ate Functions

Excel’s 7ate and ime functions allow you to use dates and times in formulas.

o perform calculations on these values, Excel converts each date and time to a

serial number. he 7ate function performs that conversion for any year, month,and day combination you enter. he ime function converts any hour, minute,

and second combination you enter.

?W and ?7"% are two of the most fre$uently used date functions. ?W

returns the date and time that the function was entered in a worksheet. ?7"%

returns only the date. Each time you open a workbook that uses one of these

functions, the date or time is updated automatically.

In March, the reservations manager needs to figure the occupancy rate for the

winter season, which runs from ovember = through the end of #ebruary. De

wants to confirm the number of days in that season.

In this exercise, you use 7ate functions to calculate the amount of time betweentwo dates.

=A2-A1

Dake sure to hoose the number format for the ell ontaining this formula!Otherwise, '&el displa#s the result in the same format as the ells used inthe alulation (in this ase, as a date*!

Using Absolute and "elati#e Cell"eferences

In Excel, you can refer to other cells either absolutely or relatively. "n

absolute reference refers to the address of a specific cell. " relative reference

refers to a cell that is a specific number of rows and columns from the cell that

contains the reference.

=ate funtions are most

useful when the date

arguments are formulas,rather than onstants!




ell references are fre$uently used in formulas. By default, cell references are

relative, even if the formula contains the row letter and column number of the

target cell. #or example, if you enter

18(M0;,C2

in cell <, the resulting value in < will be ; 3 C. If you copy this formula

to cell 7<, the formula in 7< will appear as

18(M07;,7C2

and the resulting value in cell 7< will be 7; 3 7C. Excel automatically ad!usts

the cell references relative to their new locationF that’s why they are called

GrelativeH cell references.

In some cases, however, you need cell references that won’t change when you

copy them from one location to another. #or example, a formula might refer to

a cell with a rate of interest that is always stored in a particular cell. It’s also

possible for a cell reference to have an absolute reference to a row but not to a

column, and vice versa. o make a cell reference absolute, type a dollar sign

02 before either or both of the column or row references.

#or example, = is an absolute reference to cell =. = is an absolute

reference to column , but the reference to row = is relative. = is a relative

reference to column , but the reference to row = is absolute.

tip

Using 3- references, #ou an link to ells in other worksheets orworkbooks! %his t#pe of referene an also be absolute or relati7e!

"t "dventure Works, the reservations manager is having trouble copying the

formulas in his worksheet that calculate simple averages. (sing a combination

of absolute and relative references, however, he is able to easily replicate the

formulas to compute the necessary averages.

In this exercise, you use absolute references and relative references to build and

copy a formula.

1 Open the Lodging Usage workbook with whih #ou worked earlierin this lesson!

2 =ouble-lik ell C+3!

3 %#pe a dollar sign (* before the $ in the referene to ell $, andpress 'nter!

Using Basic Statistical Functions

Excel offers hundreds of functions, many of which are very specific to certain

tasks or to people in certain occupations. Most people find that there are a

couple of functions that they use all of the time and many that they will never

have reason to use. Excel’s basic and most fre$uently used functions are shown

in the following table.

Using $umbered Series and AutoFill

When you enter data that forms a series or pattern, Excel can save you time by

completing the series for you.

If you’re entering se$uential numbers, the days of a week, the months in a year,or another series, you don’t have to type each item in the series. Lust type the

first one or two entries, and use AutoFill to finish the series for you.

#or example, if you want to enter days of the week in a worksheet, type

Monday 0or whichever day you want to start with2, and then use "uto#ill to

enter the rest of the days. If you want to enter every other day in a worksheet,

type Monday in the first cell, Wednesday in the second cell, and then use

"uto#ill to finish the series.

" new feature in the current version of Excel is the "uto #ill ?ptions button

that appears next to data you add to a worksheet using either "uto#ill or
