Arithmetic operators run mathematical operations on two expressions of one or more data types. They're run from the numeric data type category. For more information about data type categories, see Transact-SQL syntax conventions.
| Operator | Meaning |
|---|---|
| + (Add) | Addition |
| - (Subtract) | Subtraction |
| * (Multiply) | Multiplication |
| / (Divide) | Division |
| % (Modulo) | Returns the integer remainder of a division. For example, 12 % 5 = 2 because the remainder of 12 divided by 5 is 2. |
The plus (+) and minus (-) operators can also be used to run arithmetic operations on datetime and smalldatetime values.
