Operators and precedence
When you create an Excel formula, you use the built-in functions and arithmetic
operators that define operations such as addition and multiplication. In Excel,
mathematical operators are evaluated in the order shown in the following table.
Operator
Description
Negation (e.g., –1)
%
Percentage
^
Exponentiation
* and /
Multiplication and Division
+ and
Addition and Subtraction
&
Concatenation (adding two strings together)
=, >, <, >=, <=, and <>
Equals, Greater Than, Less Than, Greater Than or Equal To,
Less Than or Equal To, and Not Equal To
If two operators at the same level, such as + and , occur in the same equation, Excel
evaluates them in left-to-right order. For example, the operations in the formula = 4
+ 8 * 3 – 6 would be evaluated in this order:
8 * 3 , with a result of 24
1
4 + 24 , with a result of 28
2
28 – 6 , with a final result of 22
