Let's say you want to sum prices for all items not on sale in a store or sum gross profit margins for all departments under budget. There are several ways to add numbers.

## Add numbers in a cell

To do this task, use the + (plus sign) arithmetic operator.

For example, if you type the following formula in a cell:

=5+10

The cell displays the following result:

15

## Add all contiguous numbers in a row or column

To do this task, use AutoSum .

1. Click a cell below the column of numbers or to the right of the row of numbers.

2. On the Home tab, in the Editing group, click AutoSum , and then press ENTER.

To do this task, use the SUM function.

### Example

The example may be easier to understand if you copy it to a blank worksheet.

How to copy an example

1. Create a blank workbook or worksheet.

2. Select the example in the Help topic.

Note   Do not select the row or column headers.

Selecting an example from Help

3. Press CTRL+C.

4. In the worksheet, select cell A1, and press CTRL+V.

5. To switch between viewing the results and viewing the formulas that return the results, press CTRL+` (grave accent), or on the Formulas tab, in the Formula Auditing group, click the Show Formulas button.

 1 2 3 4 5 6 7
 A B Salesperson Invoice Buchanan 15,000 Buchanan 9,000 Suyama 8,000 Suyama 20,000 Buchanan 5,000 Dodsworth 22,500 Formula Description (Result) =SUM(B2:B3, B5) Adds two invoices from Buchanan, and one from Suyama (44,000) =SUM(B2,B5,B7) Adds individual invoices from Buchanan, Suyama, and Dodsworth (57,500)

Note    The SUM function can include up to 30 cell or range references.

## Add numbers based on one condition

You can use the SUMIF function to create a total value for one range based on a value in another range, as in the following example.

 A B Salesperson Invoice Buchanan 15,000 Buchanan 9,000 Suyama 8,000 Suyama 20,000 Buchanan 5,000 Dodsworth 22,500 Formula Description (Result) =SUMIF(A2:A7,"Buchanan",B2:B7) Sum of invoices for Buchanan (29000) =SUMIF(B2:B7,">=9000",B2:B7) Sum of large invoices greater than or equal to 9,000 (66500) =SUMIF(B2:B7,"<9000",B2:B7) Sum of small invoices less than 9,000 (13000)

The SUMIF function uses the following arguments

Formula with SUMIF function

1. Range to evaluate: Check these cells to determine whether a row meets your criteria.

2. Criteria: The condition that the cells you evaluate must meet for the row to be included in the sum.

3. Range to sum: Add the numbers in these cells provided that the row satisfies the condition.

## Add numbers based on multiple conditions

To do this task, use the IF and SUM functions.

Note    The formulas in the example must be entered as array formulas. After copying the example to a blank worksheet, select the formula cell. Press F2, and then press CTRL+SHIFT+ENTER. If the formula is not entered as an array formula, the error #VALUE! is returned.

## Add numbers based on criteria stored in a separate range

To do this task, use the DSUM function.

The DSUM function uses the following arguments.

1. Range to evaluate: The list from which you want to sum.

2. Field: The label of the column to sum.

3. Criteria: The range of cells that contains the conditions.

## Add numbers based on multiple conditions with the Conditional Sum Wizard

If you want to summarize a range of cells based on specific conditions, you can use the Conditional Sum Wizard. For example, if your range of cells contain sales amounts for different salespeople, the Conditional Sum Wizard add-in program can help you create a formula that calculates the total sales amount for one salesperson.

1. Click a cell in the range of cells.

2. On the Formulas tab, in the Solutions group, click Conditional Sum.

If the Conditional Sum command or Solutions tab are not available, then you need to load the Conditional Sum Wizard add-in program.

1. Click the Microsoft Office Button , click Excel Options, and then click the Add-ins category.

2. Select Excel Add-ins in the Manage list box, and then click Go.

3. In the Add-Ins available list, select the Conditional Sum Wizard check box, and then click OK.

3. Follow the instructions in the wizard.

Note    The formulas created by the Conditional Sum Wizard are array formulas. After you edit these formulas, you must press CTRL+SHIFT+ENTER to lock in the formulas.

To do this task, use the SUM, IF, and FREQUENCY functions.

The following example uses the:

• FREQUENCY function to identify the unique values. For the first occurrence of a specific value, this function returns a number equal to the number of occurrences of that value. For each occurrence of that same value after the first, this function returns a 0 (zero).

• IF function to assign a value of 1 to each true condition.

• The SUM function to add the unique values.

Tip    To see a function evaluated step by step, select the cell containing the formula, and then on the Formulas tab, in the Formula Auditing group, click Evaluate Formula.
