18. UC Merced - Math 15 18 Spreadsheet Fundamentals This Week:  Learning some simple operations of Microsoft Excel (or OpenOffice Calc).

19. UC Merced - Math 15 19 Identify major components of the Excel window Excel is a computerized spreadsheet, which is an important tool that helps you analyze information. Excel stores spreadsheets in documents called workbooks. Each workbook is made up of individual worksheets, or sheets.  When you open Excel, by default it will open a blank workbook with three blank worksheets.

20. UC Merced - Math 15 20 Excel components Each column is assigned Letter. Each row is assigned Numerical Number. D11 (Cell)

21. UC Merced - Math 15 21 Resize worksheet rows and columns There are a number of methods for altering row height and column width using the mouse or menus:  Here is the easiest one: Click the dividing line on the column or row, and drag the dividing line to change the width of the column or height of the row

23. UC Merced - Math 15 23 Entering Formulas A formula is a mathematical expression that calculates a value. In Excel, formulas always begin with an equal sign (=). A formula can consist of one or more arithmetic operators.

24. UC Merced - Math 15 24 Arithmetic Operators = (B1 - D15*B15)/(A1+B2^3)

25. UC Merced - Math 15 25 Use Excel ’ s Predefined functions Excel supplies more than 350 functions  predefined formulae for a commonly used calculation.

26. UC Merced - Math 15 26 Define functions, and functions within functions A basic formula example to add up a small number of cells is =A1+A2+A3+A4, but that method would be cumbersome if there were 100 cells to add up. Use Excel's SUM function to total the values in a range of cells like this: SUM(A1:A100) You can also use functions within functions. Consider the expression: =ROUND(AVERAGE(A1:A100),1)  This expression would first compute the average of all the values from cell A1 through A100 and then round that result to 1 digit to the right of the decimal point

27. UC Merced - Math 15 27 Open the Insert Function dialog box To get help from Excel for inserting a function, first click the cell in which you wish to insert the function. Then, open the Insert Function Dialog box:

30. UC Merced - Math 15 30 Identify cell ranges A group of worksheet cells is known as a cell range, or range. Working with ranges in a worksheet makes working with the data easier. Ranges can be adjacent or nonadjacent.  Select an adjacent range by L-clicking ( Left-mouse button clicking ) on a cell and dragging to an opposite corner of a rectangle of cells  A nonadjacent range is comprised of two or more adjacent ranges that are not contiguous to each other To select a nonadjacent range, begin by selecting an adjacent range, then press and hold down the Ctrl key as you select other adjacent ranges

31. UC Merced - Math 15 31 Copy and paste formulas and functions Copying and pasting a cell or range of cells is a simple, but highly effective means for quickly filling out a large worksheet. To copy and paste a cell or range:  Select the cell or range to be copied and then click the Copy button on the standard toolbar or Ctl+c.  Select the cell or range into which you want to copy the selection and then click the Paste button on the standard toolbar or Ctl-v.  Once you are finished pasting, press the Esc key to deselect the selection

32. UC Merced - Math 15 32 Copy and paste effects on cell references Copied formulas or functions that have cell references are adjusted for the target cell or range of cells. For example,  if cell G5 contains the formula =F5*B5/B7, and you copy and paste this formula to cell G6, the formula in cell G6 will be =F6*B6/B8. This may or may not be correct for your worksheet, depending upon what you are trying to do.

33. UC Merced - Math 15 33 Use relative references A relative reference is a cell reference that shifts when you copy it to a new location on a worksheet. A relative reference changes in relation to the change of location. If you copy a formula to a cell three rows down and five columns to the right, a relative reference to cell B5 in the source cell would become G8 in the destination cell.

34. UC Merced - Math 15 34 Use absolute references An absolute reference is a cell reference that does not change when you copy the formula to a new location. To create an absolute reference, you preface the column and row designations with a dollar sign ($). For example, the absolute reference for B5 would be $B$5.  This cell reference would stay the same no matter where you copied the formula.

35. UC Merced - Math 15 35 Use Excel's Auto Fill features When you need to copy and paste a large number of rows or columns, you can use a technique called Auto Fill. The fill handle is a small black square located in the lower-right corner of a selected cell or range. When you drag the fill handle  with a L-Click (Left-Click), Excel automatically fills in the formulas and formats used in the selected cells.  With a R-Click (Right-Click), Excel offers the menu for several options for Auto Fill.
