Arithmetic Operators
 reference
Arithmetic operations perform the basic mathematical operations of addition, subtraction, multiplication, division, and modulo within an expression or any numerical value retrieved as part of query clauses. Additionally, SQL++ provides a negation operation which changes the sign of a value.
These arithmetic operators only operate on numbers. In SQL++, arithmetic operators have their usual meaning. However, in any of these expressions:

Syntax
There are six different arithmetic syntaxes:
arithmeticterm ::= expr '+' expr 
expr '' expr 
expr '*' expr 
expr '/' expr 
expr '%' expr 
'' expr
Operator  Description 

+ 
Add values. 
 
Subtract right value from left value. 
* 
Multiply values. 
/ 
Divide left value by right value. 
% 
Modulo. Divide left value by right value and return the remainder. NOTE: Modulo is an integer operator and will use only the integer part of each value. 
 
Negate value.
