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.

For more information about the precision and scale of an arithmetic operation result, see Precision, Scale, and Length (Transact-SQL).
