# Create a simple formula

** Important ** The calculated results of formulas and some Excel worksheet functions may differ slightly between a Windows PC using x86 or x86-64 architecture and a Windows RT PC using ARM architecture. Learn more about the differences.

You can create a simple formula to add, subtract, multiply or divide values in your worksheet. Simple formulas always start with an equal sign (**=**), followed by constants (constant: A value that is not calculated. For example, the number 210 and the text "Quarterly Earnings" are constants. An expression, or a value resulting from an expression, is not a constant.) that are numeric values and calculation operators (operator: A sign or symbol that specifies the type of calculation to perform within an expression. There are mathematical, comparison, logical, and reference operators.) such as plus (**+**), minus (**-**), asterisk(*****), or forward slash (**/**) signs.

For example, when you enter the formula **=5+2*3**, Excel multiplies the last two numbers and adds the first number to the result. Following the standard order of mathematical operations, multiplication is performed before addition.

- On the worksheet, click the cell in which you want to enter the formula.
- Type the
**=**(equal sign) followed by the constants and operators that you want to use in the calculation.

You can enter as many constants and operators in a formula as you need, up to 8192 characters.

** Tip ** Instead of typing the constants into your formula, you can select the cells that contain the values that you want to use and enter the operators in between selecting cells.

- Press Enter.

** Notes **

- To quickly add values, you can use
**AutoSum**instead of entering the formula manually (**Home**tab,**Editing**group). - You can also use functions (such as the SUM function) to calculate values in your worksheet. For more information see Create a formula by using a function.
- To take it one step further, you can use cell references and names instead of the actual values in a simple formula. For more information, see Use cell references in formulas and Define and use names in formulas.
