7/30/2019 Excel Basic Formulae http://slidepdf.com/reader/full/excel-basic-formulae 1/17 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. Click AutoSum on the Standardtoolbar, and then press ENTER. TOP OF PAGE Add noncontiguous numbers 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
=SUM(IF((A2:A11="South")*(C2:C11="Meat"),D2:D11))Sum of Meat sales in theSouth region (14719)
=SUM(IF((A2:A11="South")+(A2:A11="East"),D2:D11)) Sum of sales where theregion is South or East(32753)
NOTE The formulas in the example must be entered as array formulas. After copying theexample to a blank worksheet, select the formula cell. Press F2, and then press CTRL+SHIFT+ENTER. If theformula is not entered as an array formula, the error #VALUE! is returned.
Add numbers based on criteriastored in a separate range
=COUNTIF(A2:A7,A4) Number of entries for Suyama (2)
=COUNTIF(B2:B7,"< 20000") Number of invoice values less than 20,000 (4)
=COUNTIF(B2:B7,">="&B5) Number of invoice values greater than or equal to 20,000(2)
Count numbers greater than or less than a number
To count numbers greater than or less than a number, use the COUNTIF function. To countnumbers that fall between a range of numbers, you can use the SUMPRODUCT function.

How to copy an example
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.
=COUNTIF(B2:B7,"<=9000") Numbers less than or equal to 9000 (3)
=SUMPRODUCT((B2:B7>=9000)*(B2:B7<=22500))The SUMPRODUCT function counts the number
of cells in the range B2:B7 that contain numbersgreater than or equal to 9000 and less than or equal to 22500 (4).
Convert measurements
Show All
Let's say you want to know how many kilometers that you ran on a quarter-mile track or atolerance level using metric values. To convert measurements, use the CONVERT function.
The CONVERT function converts a wide range of measurements, including measures of
weight, distance, time, pressure, force, energy, power, magnetism, temperature, and liquidmeasure.
If the CONVERT function is not available, install and load the Analysis ToolPak add-in.

Formula Description (Result)
=CONVERT(A2,"C","F") Convert 6 degrees Celsius to Fahrenheit(42.8)
=CONVERT(A2,"tsp","tbs")Convert 6 teaspoons to tablespoons (2)
=CONVERT(A2,"gal","l") Convert 6 gallons to liters (22.71741274)
=CONVERT(A2,"mi","km") Convert 6 miles to kilometers (9.656064)
=CONVERT(A2,"km","mi") Convert 6 kilometers to miles (3.728227153)
=OR(EXACT(B2, A2:A4))Compares "Grape" to each value in the list
(FALSE)
NOTE The formula in the example must be entered as an array formula. After copying theexample to a blank worksheet, select each formula cell individually. Press F2, and then pressCTRL+SHIFT+ENTER. If the formula is not entered as an array formula, the error #VALUE! isreturned.
Combine two or more columns by using a function

Calculate the average of numbers not in acontiguous row or column
To do this task, use the AVERAGE function.

=AVERAGE(A2:A4,A7) Averages the top three and the last number in the list (7.5)
=AVERAGE(IF(A2:A7<>0, A2:A7,""))
Averages the numbers in the list except those that contain zero,such as cell A6 (11.4)
NOTE The last formula in the example must be entered as an array formula. After copyingthe example to a blank worksheet, select the cell A11. Press F2, and then pressCTRL+SHIFT+ENTER. If the formula is not entered as an array formula, the error #VALUE! isreturned.
To do this task, use the SUMPRODUCT and SUM functions.

Formula Description (Result)
=SUMPRODUCT(A2:A4,B2:B4)/SUM(B2:B4)Divides the total cost of all three orders by the totalnumber of units ordered (24.66)
Calculate the average of numbers, ignoringzero (0) values
To do this task, use the AVERAGE and IF functions.

Create conditional formulas
Testing whether conditions are true or false and making logical comparisons betweenexpressions are common to many tasks. You can use the AND, OR, NOT, and IF function tocreate conditional formulas.
The IF function uses the following arguments.
Formula with the IF function
logical_test: The condition that you want to check.
value_if_true: The value to return if the condition is true.
value_if_false: The value to return if the condition is false.
Create a conditional formula that results in a logical value(TRUE or FALSE)
To do this task, use the AND, OR, and NOT functions, and operators.
