Practical Computer Literacy, 2nd edition Chapter 12

16. Practical Computer Literacy, 2nd edition Chapter 12
How do I enter values?
A value can be edited just as you would edit a label – in the cell or in the Formula bar
Excel makes assumptions about the values as you enter them
Type an apostrophe (‘) before a number to specify it as a label
Practical Computer Literacy, 2nd edition Chapter 12

17. Practical Computer Literacy, 2nd edition Chapter 12
How do I enter values?
Use the Fill handle to automatically enter values with technique called drag-and-fill
Point to the bottom-right corner of a cell. When the pointer changes to a black cross shape, drag the pointer across or down other cells
Displays the Auto Fill Options button
Fill with series of numbers
Fill with value of initial cell with or without formatting
Fill with cell formatting without a value
Practical Computer Literacy, 2nd edition Chapter 12

18. Practical Computer Literacy, 2nd edition Chapter 12
How do I enter formulas?
A formula specifies how to add, subtract, multiply, divide, or otherwise calculate values in cells
Formulas always begin with an equal (=) sign and can use cell references that point to other cells
A cell reference is the column and row location of a cell
Practical Computer Literacy, 2nd edition Chapter 12

19. Practical Computer Literacy, 2nd edition Chapter 12
How do I enter formulas?
For example, the formula =C2-C3 subtracts the contents of cell C3 from the contents of cell C2
Common arithmetic operators are:
- (subtraction) / (division)
+ (addition) % (percent)
* (multiplication) ^ (exponent)
Practical Computer Literacy, 2nd edition Chapter 12

20. Practical Computer Literacy, 2nd edition Chapter 12
How do I enter formulas?
To enter a formula:
Click the cell where you want the result of the formula to appear. Type the equal sign (=).
Click the first cell referenced in the formula. A marquee, which is a rectangle of dashes, will surround the cell just clicked.
Type an arithmetic operator (+,-,*,/) then click the next cell referenced in the formula.
Press Enter to end the formula.

21. Practical Computer Literacy, 2nd edition Chapter 12
How do I enter formulas?
A formula can also be typed directly into the cell
Edit a formula in the cell or in the Formula bar the same as labels and values

23. How do I create complex formulas?
Complex statistical, financial, and mathematical formulas can be created in Excel.
Use parentheses to make sure the operations in a formula are executed in the correct order.
Without parentheses, Excel will calculate using the order – multiplication and division, then addition and subtraction.
Practical Computer Literacy, 2nd edition Chapter 12

24. How do I create complex formulas?
By using parentheses you can specify the order of calculation.
For example, in the formula, =B3+C3*1.2, Excel will multiply cell C3 by 1.2 then add that to the value in cell B3.
Practical Computer Literacy, 2nd edition Chapter 12

25. How do I create complex formulas?
In the formula, =(B3+C3)*1.2, Excel will add cell B3 to cell C3 then multiply the result by 1.2
A formula can include values, cell references, or both.
Copying or moving formulas can lead to unexpected results

How do I use functions?
Excel includes many predefined formulas, called functions
Excel includes these examples:
Financial functions – payments and net value
Mathematical and trigonometric function – absolute value and arctangent
Statistical functions – average and normal distribution
You can use the Insert Function button to select a function from a list. There are more than 250 from which to choose
Clicking on a function in the list will display a tip about the function’s use

29. Practical Computer Literacy, 2nd edition Chapter 12
How do I use functions?
The Payment or PMT function calculates the payments for a loan
The PMT function will calculate loan payments for a car or a house, among others
Functions can include multiple functions
Practical Computer Literacy, 2nd edition Chapter 12

30. Practical Computer Literacy, 2nd edition Chapter 12
How do I use functions?
Arguments are values or cell references used in the function for calculations.
For example, the Average function’s argument is a series of numbers or cell references used in the calculation.
The result is the average of the values.
Practical Computer Literacy, 2nd edition Chapter 12

31. Practical Computer Literacy, 2nd edition Chapter 12
How do I use functions?
To select a range of cells for your argument, click and drag to select the range.
Some functions need more than one argument and they may be required or optional.
The PMT function, for example, requires three arguments and two optional arguments.
Practical Computer Literacy, 2nd edition Chapter 12

32. Practical Computer Literacy, 2nd edition Chapter 12
How do I use functions?
It can be difficult to enter arguments for a function.
If you need help, click Help on this function link.
When using a new function check results with calculator.

34. How do I use the AutoSum button?
The AutoSum button is used to quickly calculate the total of a column or row of cells.
Excel examines cells to the left and above current cell to determine inclusion.
The AutoSum button can be tricked by a blank cell or a cell containing a label. It is always wise to double-check the range.
Practical Computer Literacy, 2nd edition Chapter 12

35. How do I use the AutoSum button?
Be careful using the AutoSum button to calculate a range in a column with a numeric heading
Watch the marquee to verify the range
If the AutoSum button does not automatically select the correct cells, create the Sum function manually
