Microsoft Excel Computer & Careers Mr. Lewis

Definitions: SpreadsheetIs an application you use to perform numeric calculations and to analyze and present numeric data WorksheetThe electronic spreadsheet you work in. WorkbookThe file that the worksheet is contained in (file extension.xlsx) FormulasAre equations in a worksheet. You use a formulas to make calculations as simple as adding a column of numbers, or as complex as profit and loss projections. File ExtensionBefore 2007 =.xls 2007 and after =.xlsx When you open a spreadsheet the default name is Book 1

Touring The Excel Window Name Box Formula Bar Cell Cell Address Active Cell (Sheet Tabs) (3 tabs are the default) (Sheet Tab Scrolling Buttons) (Mode Indicator) AutoSum Columns, designated with LETTERS, columns are VERTICAL (run up and down). Rows, designated with NUMBERS, rows are HORIZONTAL (run side to side)

In Creating Calculations in Excel, It Is Important to: Know where the formulas should be. Know exactly what cells and arithmetic operations are needed. Create formulas with care Use Cell references rather than values. Determine what calculations will be needed.

Excel Arithmetic Operators OperatorPurposeExample +Addition=a5+a7 -Subtraction=a5-a10 *Multiplication=a5*a11 /Division=a5/a3 %Percent=35% ^(caret)Exponent=6^4

Definitions: Labels Examples: “Travel Expenses” “Total Expenses” “Average Cost” “2009 Sales” Are entries that contain text and numerical information not used in calculations, such as “2009 Sales” or “Travel Expenses”. Labels help you identify data in a worksheet rows and columns, making your worksheet easier to understand. Values Examples: =a5 * a7 =sum(d1:d9)+ 10 Are numbers, formulas, and functions that can be used in calculations. To enter a calculations you type an equal sign (=) plus the formula for the calculation.

Definitions Cont. FunctionIs a built in formula (like a shortcut) Arguments They are the part of the function enclosed in round brackets (parentheses) following the function’s name. Arguments supply the data for the function to use in its calculations. =sum(b9:b12) FunctionArgument

Common Pointers In Excel Normal Pointer (Indicates Ready Mode) Fill Handle Pointer (Create a Alpha, Numeric Series in a Range) I-Beam Pointer (Appears in Formula Bar) Move Pointer (Changes Location on Spreadsheet)

Switching Worksheet Views Normal View Normal View: This is the default setting view when you open Excel. Page Layout View Page Layout View: This provides a more accurate view of how a worksheet will look when printed. The margins of the page are displayed, along with the text box for the header and the ruler. Part of the page to the right is shown in this view. Page Break View Page Break View: displays a reduced view of each page of your worksheet, along with page break indicators. Full Screen View Full Screen View: displays the worksheet on the entire screen.

Functions VS Simple Formulas Examples of Functions: =sum(a1:a5) =max(a1:a5) =min(a1:a5) =average(a1:a5) =count(a1:a5) ** The function is the WORD that is at the beginning of the formula. Examples of Simple Formulas: =a6 - a7 =d3 + d4 + d5 =c5 - c6 - c7 Simple formulas only use one arithmetic operator. ** Simple formulas do not use words, they just use simple arithmetic. **** Important: Both formulas use cell referencing
