Seminar Agenda• Unit Four Grading• Unit Five Activities• Questions

Unit Four Assignments• Unit Four Assignments have

been graded and are in the grade book.

• If you have not uploaded the assignments, you still have time.

• Unit Four assignments are worth 80 pts, so it is best to turn in, and receive partial points.

Unit 5 Assignments I received some

emails this weekend, in which students asked about the assignments for Unit 5.

Question: Sounds elementary I know, but please enter the assignments for Unit 5.

You do not have to enter the file names, just which assignments you have for this week.

Unit 5 – Welcome to Excel• Unit A objectives:

– Understand spreadsheet software– Tour the Excel 2007 window– Understand formulas– Enter labels and values and use AutoSum– Edit cell entries– Enter and edit a simple formula– Switch worksheet views– Choose print options

Unit Five Assignments• Unit A, p. Excel 1-17• Unit B, p. Excel 25-41

– Creating a complex formula – Inserting a function– Typing a function

•  

Excel Basics• Microsoft Excel is an electronic

spreadsheet program, that allows you to perform numeric calculations.–The Excel file is called a

_________–Within this _____________ there

can be several individual “pages”, called ____________.

Excel Basics–The spreadsheet is called a

worksheet• Individual worksheets are stored in a workbook which is the Excel file.

The Excel 2007 Window

Excel Basics

• Each cell has its own unique location called a cell reference

• Question: For example, where is the cell reference A1 located?

Excel Basics• A1: Cell where Row 1 and Column A

intersect.

Excel Basics• How do I know which cell is the “active cell”

or selected?

Excel Basics• The Name Box will display the active or

selected cell.

Understanding Formulas• When creating calculations in

Excel, it is important to:– Know where the formulas

should be– Know exactly what cells and

arithmetic operations are needed

– Use cell references rather than values

Understanding Formulas

Creating a formula• Question: What symbol should you

enter first when beginning a formula?a) :b) =c) /d) *

Creating a formula• Question: What symbol should you

enter first when beginning a formula?a) :

b)=c) /d) *

Understanding Formulas• True or False:

– You can only enter formulas in the formula bar.

Understanding Formulas• False:

– You can enter formulas in the formula bar or in a cell.

Understanding Formulas

Excel arithmetic operatorsExcel arithmetic operators

Creating a Complex Formula

• A complex formula is an equation that uses more than one type of arithmetic operator–Example: formula that uses

both addition and multiplication

–Arithmetic operations are performed according to the order of precedence

Creating a Complex Formula

Creating a Complex Formula • Order of precedence in Excel

formulas1. Operations inside parentheses are

calculated first2. Exponents are calculated next3. Multiplication and division are

calculated next (from left to right)4. Addition and subtraction are

calculated next (from left to right)

Complex Formula Example• Question: Let’s talk about the Round

formula used in Excel Unit B:

=ROUND(B17+B17*0.2,0). • According to order of precedence,

how would Excel complete this formula?

Complex Formula Example• Question: Let’s talk about the Round

formula used in Excel Unit B:

=ROUND(B17+B17*0.2,0). • According to order of precedence,

how would Excel complete this formula?

• B17*0.2, then add the total to B17.• What does the zero indicate?

Complex Formula Example• Question: Let’s talk about the Round

formula used in Excel Unit B:

=ROUND(B17+B17*0.2,0). • What does the zero indicate?

– No decimal places in the formula

Absolute and Relative Cell References

• Relative cell references allow you to copy formulas from one cell to another, and allow the “new data to replace the old.” – For example, if you copy a formula from

cell B6, which adds up cells B1 to B5, to cell E6, the formula should change to include cell entries from column E.

Understanding Relative and Absolute Cell References

=SUM(B5:B22)

Understanding Relative and Absolute Cell References

Absolute Cell References• Absolute cell references allow you

to copy formulas from one cell to another, and to not “copy over” the original cell reference.– For example, if you multiply B5 X $B$22,

with an absolute cell reference,

Absolute Cell Reference

• Turn to page Excel 38 in your textbook, and let’s take a quick look at the text.

Inserting a Function

• A function is a predefined formula that makes it easy to perform a complex calculation

Typing a Function• Can be found on the Formulas ribbon,

in the Function Library.

Typing a Function• A function/formula can be typed

manually into a cell– You must know the name and

initial characters of the function• When typing a function begin with =• Once you type an equal sign, each

letter you type activates the AutoComplete feature– What do I mean by the

AutoComplete feature?

Typing a Function • Auto Complete “enters” text for you,

based on the text you just typed.• You do not have to accept the

suggested text, just continue typing.
