Arithmetic operators perform mathematical operations on two expressions of one or more of the data types of 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 perform arithmetic operations on datetime and smalldatetime values.
For more information about the precision and scale of the result of an arithmetic operation, see Precision, Scale, and Length (Transact-SQL).
