Creating a Worksheetin Calc
2
What’s in the Calc window?
Worksheet(or sheet)
Consists of a grid of columns (labeled with letters) and rows (labeled with numbers)
Workbook Contains one or more worksheets, each represented by a tab
Worksheet cell (or cell)
Rectangle formed by intersection of a column and row
Each has a unique name (e.g., B3)
3
What’s in the Calc window? (continued)
Active cell The cell you can currently edit or modify
Change by clicking another cell or pressing arrow keys
Range Series of cells (e.g., D3:D6)
Select a range by clicking cell in top-left corner of the range and dragging the mouse to bottom-right cell in the range

5
How do I enter labels?
Label• Any text entered into a cell of the worksheet
• Use to describe numbers you’ve entered in other cells and for text data (e.g., names of people)
• Any “number” data not intended for use in a calculation should be entered as a label (e.g., telephone number)
Click cell and enter label• Text extends into neighboring cells if too long
6
How do I enter labels? (continued)
7
How do I enter labels? (continued)
To make a long label “wrap”
Select cell(s), click Format Click Cells on menu bar to display Format
Cells dialog box Click Alignment tab, then click Wrap text
automatically check box
To edit a label after pressing Enter
Click cell, click Input line in Formula Bar Use left/right arrow keys to move
insertion point, and Backspace and Delete keys to delete characters
To edit a label inside a cell
Double-click cell to activate Edit contents using arrow, Backspace,
and Delete keys
8
How do I enter values?
Value• Number intended to be used in a calculation
Click a cell to make it active, and enter the (unformatted) value into the cell
9
How do I enter values? (continued)
10
How do I enter values? (continued)
To indicate a negative value
Type a minus sign before the number
To specifically enter a number as a label
Type an apostrophe before the number
To enter values automatically
Use fill handle anddrag-and-fill technique
Use Fill option on Edit menu
11
How do I enter formulas?
Formula• Specifies how to add, subtract, multiply, divide, or
otherwise calculate values in worksheet cells
• Always begins with a equal sign
• Can use cell references (column and row location) that point to contents of other cells
12
How do I enter formulas? (continued)
Most common arithmetic operators• Subtraction –
• Addition +
• Multiplication *
• Division /
• Percent %
• Exponent ^
13
How do I enter formulas? (continued)
Use the pointer method (easiest way)• Click cell where results should appear, type “=”
• Click cell that contains first number to reference in the formula
• Type an arithmetic operator, then click the next cell to reference
• Continue until formula is complete
Type formula directly into cell
14
How do I enter formulas? (continued)
15
How do I create complex formulas?
Use arithmetic operators, parentheses, and a mixture of values and cell references to calculate statistical, financial, and mathematical equations
Use parentheses to specify order for calculation
Be aware: cell references in formulas can lead to unexpected results when formulas are copied or moved
16
How do I create complex formulas? (continued)
17
How do I use functions?
Function: predefined formula
Calc includes more than 250 functions – financial, mathematical and trigonometric, statistical – including Sum, Average, Minimum, Maximum, and Payment
18
How do I use functions? (continued)
Verify that formulas and functions reference correct cells and data• Avoid circular references
Formulas can include multiple functions
19
How do I use functions? (continued)
Use Function Wizard button to select a function from a list
Specify arguments (values or cell references used to calculate result of function)• Click top-left cell containing data to use in the
function, then drag down to bottom-right cell
• Release mouse button to display selected range of cells in dialog box
• Click OK button to calculate
20
How do I use functions? (continued)
21
How do I use functions? (continued)
22
How do I use functions? (continued)
Some functions use more than one argument, and those arguments may be required or optional
Be careful using functions you don’t fully understand
Check results with a calculator to make sure the function is working as expected
23
How do I use the Sum button?
Quickly creates a function to calculate the total of a column or row of cells
Calc examines cells to left of and above current cell to determine cells to include in total
24
How do I use the Sum button? (continued)
25
How do I use the Sum button? (continued)
Cells included in Sum function are displayed as a range or as a series of adjacent cells
Sum works best if every cell in the row or column of cells contains a value
Check the marquee to ensure that the correct range of cells is selected before pressing Enter
26
How do I use the Sum button? (continued)
If Sum button does not automatically select the correct cells:• Press Esc key to remove the function and create
the Sum fraction manually
• Drag across the correct range of cells to select them; press Enter to complete the function
