Write Formulas

Operator Function

+ addition

- subtraction

* multiplication

/ division

% percent

^ exponentiation


Write Formulas - continued

If a formula contains two or more operators, Excel uses the same order of operations used in algebra.

From left to right in a formula, this order, called the order of operations, is: negations (negative number—a number preceded by a minus sign) first, then percents, then exponentiations, followed by multiplications, divisions, additions, and finally subtractions.



Copy a Formula Relatively:1. Insert formula in cell.2. Select cell containing formula

and all cells you want to contain formula.

3. Click Fill button.4. Click desired direction.

Fill button



To copy a relative formula using the fill handle:1. Insert formula in cell.2. With cell active, position mouse pointer on fill handle. 3. Hold down left mouse button, drag and select desired

cells, and then release mouse button.

Write a formula by pointing:1. Click cell that will contain

the formula.2. Type equals sign.3. Click cell you want to

reference in formula.4. Type desired mathematical

operator.5. Click next cell reference.6. Press Enter.

To use the Trace Error button:1. Click Trace Error

button when it appears.

2. Select an option from drop-down list.

Trace Error button



Excel is a sophisticated program that requires data input and formula creation to follow strict guidelines in order to function properly.

When guidelines that specify how data or formulas are entered are not followed, Excel will display one of many error codes.

When an error is identified with a code, determining and then fixing the problem is easier than if no information is provided.



Error Code Meaning

#DIV/O A formula is attempting to divide a number by zero.

#N/A An argument parameter has been left out of a function.

#NAME? A function name is not entered correctly.

#NUM! An argument parameter does not meet a function’s requirements.

#REF! A referenced cell no longer exists within a worksheet.

#VALUE The data entered is the wrong type (for example, text instead of numbers).


Insert Formulas with Functions

=SUM(B2:B5) is an example of a formula. The beginning section of the formula, =SUM, is called a function, which is a built-in formula.

A function operates on what is referred to as an argument.

An argument may also contain a constant. When a value calculated by the formula is inserted in a

cell, this process is referred to as returning the result.

Excel performs over 300 functions that are divided into thirteen different categories including Financial, Date & Time, Math & Trig, Statistical, Lookup & Reference, Database, Text, Logical, Information, Engineering, Cube, Compatibility, and Web.



Excel includes the Formula AutoComplete feature that displays a drop-down list of functions.

Write Formulas with Statistical Functions

AVERAGE function

The AVERAGE function returns the average (arithmetic mean) of the arguments.


Write Formulas with Statistical Functions - continued

MIN function

The MAX function in a formula returns the largest value in a cell range. The MIN function returns the smallest value in a cell range.


Write Formulas with Statistical Functions - continued

COUNT function

Use the COUNT function to count the number of cells that contain numbers within the list of arguments.


CHECKPOINT 11) When writing your own formula,

begin the formula with this.a. division signb. minus signc. plus signd. equals sign

3) A function operates on what is referred to as this.a. a cellb. a selectionc. a ranged. an argument

2) If you want to change the order of operations, use these around the part of the formula that you want calculated first.a. minus signsb. equals signsc. parenthesesd. plus signs

4) Use this function to count the numeric values in a range.a. ADDb. TOTALc. SUMd. COUNT

Write Formulas with NOW and TODAY Functions

Date & Time button

The NOW and TODAY functions are part of the Date & Time category of functions.

The NOW function returns the current date and time in a date and time format.

The TODAY function returns the current date in a date format.


Display Formulas

In some situations, you may need to display the formulas in a worksheet rather than the results of the formula.

Display all formulas in a worksheet, rather than the results, by clicking the FORMULAS tab and then clicking the Show Formulas button in the Formula Auditing group.

You can also turn on the display of formulas with the keyboard shortcut Ctrl + `.

Press Ctrl + ` to turn off the display of formulas or click the Show Formula button on the FORMULAS tab.


Use Absolute and Mixed Cell References A reference identifies a cell or a range of cells in a

worksheet and can be relative, absolute, or mixed. A relative cell reference refers to cells relative to a

position in a formula. An absolute cell reference refers to cells in a specific

location. A mixed cell reference does both: either the column

remains absolute and the row is relative or the column is relative and the row remains absolute.

Distinguish between relative, absolute, and mixed cell references using the dollar sign ($).


Use Absolute and Mixed Cell References - continued

absolute cell reference

In some situations, you may want a formula to contain an absolute cell reference, which always refers to a cell in a specific location.


Use Absolute and Mixed Cell References - continued

mixed cell reference

In a mixed cell reference, either the column remains absolute and the row is relative or the column is relative and the row is absolute.


CHECKPOINT 21) Display all formulas in a

worksheet rather than the results by pressing these keys.a. Ctrl + \b. Ctrl + `c. Ctrl + -d. Ctrl + =

3) This function returns the serial number of the current date and time.a. MINb. MAXc. DATEd. NOW

2) This function in a formula returns the largest value in a cell range.a. MINb. COUNTc. MAXd. AVERAGE

4) This type of reference always refers to a cell in a specific location.a. standardb. defaultc. relatived. absolute
