Note: Array formulas can't be input if there is anything blocking the output range. If you remove the blockage, the formula will spill as expected.

The first Excel function you should be familiar with is the one that performs the basic arithmetic operation of addition:.

In the syntax of all Excel functions, an argument enclosed in [square brackets] is optional, other arguments are required. Meaning, your Sum formula should include at least 1 number, reference to a cell or a range of cells. For example:. If necessary, you can perform other calculations within a single formula, for example, add up values in cells B2 through B6, and then divide the sum by To sum with conditions, use the SUMIF function: in the 1st argument, you enter the range of cells to be tested against the criteria A2:A6 , in the 2nd argument - the criteria itself D2 , and in the last argument - the cells to sum B2:B6 :.

In your Excel worksheets, the formulas may look something similar to this:. Its syntax is similar to SUM's:. Sums values in cells B2 through B6, and then divides the result by 5. And what do you call adding up a group of numbers and then dividing the sum by the count of those numbers?

Yep, an average! So, instead of dividing sum by count, you can simply put this formula in a cell:. For our sample data set, the formulas will be as simple as:. If you are curious to know how many cells in a given range contain numeric values numbers or dates , don't waste your time counting them by hand.

In both formulas, you use the so-called "whole column reference" B:B that refers to all the cells within column B. Judging by the number of IF-related comments on our blog, it's the most popular function in Excel. In simple terms, you use an IF formula to ask Excel to test a certain condition and return one value or perform one calculation if the condition is met, and another value or calculation if the condition is not met:. For example, the following IF statement checks if the order is completed i.

As the result, if cell C2 is not empty, the formula returns "Yes", otherwise "No":. If your obviously correct Excel formulas return just a bunch of errors, one of the first things to check is extra spaces in the referenced cells You may be surprised to know how many leading, trailing and in-between spaces lurk unnoticed in your sheets just until something goes wrong!

There are several ways to remove unwanted spaces in Excel, with the TRIM function being the easiest one:. For example, to trim extra spaces in column A, enter the following formula in cell A1, and then copy it down the column:. It will eliminate all extra spaces in cells but a single space character between words:. Whenever you want to know the number of characters in a certain cell, LEN is the function to use:. Wish to find out how many characters are in cell A2?

Just type the below formula into another cell:. Please keep in mind that the Excel LEN function counts absolutely all characters including spaces :. Use parentheses to identify the arguments of functions and to override the order of operations. Parentheses serve 2 functions in Excel, to identify the arguments of functions and to specify a different order of operations than the normal order.

Functions are pre-defined formulas. Functions may be nested within other functions, up to 64 levels deep. Parentheses in operations may be nested inside each other; the operation in the innermost set of parentheses will be performed first. Whether nesting parentheses in mathematical operations or in nested functions, always be sure to have as many close parentheses in your formula as you do open parentheses, or you'll receive an error message.

Method 2. Type an equal sign the cell or in the formula bar. The formula bar is located above the rows and columns of cells and beneath the menu bar or ribbon. Type an open parenthesis if necessary. Depending on the structure of your formula, you may need to type several open parentheses. Create a cell reference.

You can do this in 1 of several ways: Type the cell reference manually. Select a cell or range of cells in the current page of the spreadsheet. Select a cell or range of cells in another page of the spreadsheet. Select a cell or range of cells on a page of a different spreadsheet. Enter a mathematical, comparison, text, or reference operator if desired. For most formulas, you'll use a mathematical operator or 1 of the reference operators. Repeat the previous 3 steps as necessary to build your formula.

Type a close parenthesis for each open parenthesis in your formula. It is called a semicolon, which can be used in programming languages to separate the statements or print variables by using one output statement. Yes No. Not Helpful 1 Helpful 8.

When you first start working with complex formulas, it may be helpful to write the formula out on paper before entering it into Excel. If the formula looks too complex to enter into a single cell, you can break it down into several parts and enter the parts into several cells, and use a simpler formula in another cell to combine the results of the individual formula parts together.

Microsoft Excel offers assistance in typing formulas with Formula AutoComplete, a dynamic list of functions, arguments, or other possibilities that appears after you type the equal sign and the first few characters of your formula. Press your "Tab" key or double-click an item in the dynamic list to insert it in your formula; if the item is a function, you will then be prompted to enter its arguments.

You can turn this feature on or off by selecting "Formulas" on the "Excel Options" dialog and checking or unchecking the "Formula AutoComplete" box. You access this dialog by selecting "Options" from the "Tools" menu in Excel , from the "Excel Options" button on the "File" button menu in Excel , and by selecting "Options" on the "File" tab menu in Excel When renaming the sheets in a multi-page spreadsheet, make it a practice not to use any spaces in the new sheet name.
