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, seeTransact-SQL syntax conventions. OperatorMeaning ...
When there is more than one arithmetic operator in an expression, multiplication and division are calculated first, followed by subtraction and addition. When all the arithmetic operators in an expression have the same level of precedence, the order of execution is left to right. ...
This operator adds values on either side of the operator. 4 - (Subtraction) This operator subtracts right-hand operand from left-hand operand. 5 - (Unary minus) This operator is used to change the sign of the operand. 6 / (Division) This operator divides left-hand operand by right...
Operator Result Type Description A + B All numeric types A plus B. The result type is associated with the operation data type. For example, if floating-point number is added to an integer, the result will be a floating-point number. ...

Given that an addition operator doesnotknow whether a number is a measurement or an exact quantity then it has no option other than to return the exact answer (the fourth case). How this result is interpreted is up to the application, and that application is at liberty to apply some round...
