Introduction
           What is a spreadsheet?
                      Matrix of cells
                      Recalculates as you change contents of other cells
                      Can graph quickly and easily
                      Shows impact of 1 variable on an entire system

          My spreadsheet history
                   Grandfather's graph paper
                   Fantasy baseball in school
                   Messed up first time using
                   15+ years work experience
                   Teaching Fin 325 (CSULA) and FINC 474 (Pepperdine)

Parts of an Excel spreadsheet
           Very different than the pre-2007 version, including common operations as bottons on top
           More record lines (1,000,000)

          The Office Button
                    Takes the place of the File menu
                    Quick-access toolbar is at top, for macros or favorite buttons.
          Menu Bar
                    Below the title bar, everything is displayed in groups of butons
                    Click or use Alt-(underlined letter)
          Formula Bar
                   Type formula
                   x to clear, checkmark to accept
                   fx to select formula

          Worksheet Area
                   256 columns x 1+ million rows
                   Nomenclature: (Column Letter)(Row Number)
                   Active cell displayed in upper left of Formula Bar

          Sheet Tabs- a 3-D workspace
                    Combine multiple Worksheets into Workbook
                    Right-click to copy, paste, move, delete, color, etc.
                    Hold dow Shift and drag/drop data cells to work with elwhere.
                    Control-select multiple worksheets to clone work
                    DVD buttons move between large numbers of sheets
                    Right-click DVD buttons to move to a specific sheet

          Status Bar
                       Select multiple number-filled cells to show Sum

Basic Spreadsheet Usage
          Navigating
                    Arrows for short distances
                    Scroll bars for larger distances
                    Control-X cut, Control-V Paste, Control-C copy
                    Click on cell or type cell in formula bar to select
                    Click-and-drag or Shift-arrows to select multiple cells
                    Control-click to select discontiguous cells
                    Excel uses Select + Act to complete tasks

          Entering Data (i.e. text and numbers)
                    Excel formats text differently from numbers
                    AutoFill to repeat patterns

          Formatting & Alignment
                    Text defaulted to align-left
                    Numbers defaulted to align-right
                      Change font type and size using Font color in Font section of the home toolbar
                      Most can be acessed without ay help but thre is a button to blow out the Alignment
                      Use Horizontal "Center Across Selection" for multiple cells
                      Change number type using the little box in the Font section.

            Changing Data Positioning
                     Select column letter or row number and use Insert-Cells
                     Or Drag-and-Drop data into new cells
                     Double-click on line between column labels to resize
                     Or use Format-Column Width-Auto Fit Selection

Basic Formula Usage
          Entering Formulas
                    Start with "="
                    Type cell names or click on cells to make references
                    Can type directly in cell or use Formula Bar

            Formatting Numbers
                      Can use Number Formatting Icons or Format-Cells-Number
                      Use Format-Cells-Number to change number type or decimals displayed
                      Or use Increase Decimal Places or Decrease Decimal Places icons

            Copying and Moving Formulas
                     Excel uses "relative" cell references unless specified
                     This means any copied formulas will update automatically.
                     Use Edit-Copy or Control-C to copy; Edit-Paste or Control-V to paste.
                     Can also use AutoFill just like with hardcoded numbers
                     Can paste copied formulas into multiple cells by selecting them with mouse.
                     Move formulas with, Edit-Cut, Control-X Control-V, or Drag-and-Drop
                     Moving formulas will not change their references. Copying them will.

Functions
            Order of Operation
                      Excel uses same rules as algebra: PEMDAS
                      x = 2 + 4 / 3 = 3.33
                      x = (2 + 4) / 3 = 2
            Sales Growth
                      Cannot simply look at the first and last figures
                      Need to compound growth percentage over n periods
                      May not match individual yearly numbers, but the total will
                      CAGR is the same as the geometric mean of all yearly growth rates
            Using Excel's Built-In Functions
                    Insert-Function and make choice
                    Function macros are additional functions not included with Excel
                    GeoMean is the average componed growth rate

Charts & Graphs
          Purpose of Charts & Graphs
                     Look nice
                     Help you spot trends immediately that you might otherwise miss

                     4. Confirm placement on current page to embed with numbers
          Formatting Axes
                     Double-click axis and select Scale Tab
                     Check "Categories in Reverse Order" box

                     Different data sets are better on different types of graphs

Printing
           Setup
                        First, do a Print Preview to see where things stand
                        Select Print-Page Setup to make adjustments
