The Recital/4GL supports the use of the following Mathematical Operators:

Operator	Operation	Precedence	Data Types
()	Parentheses	1	N,C,D
**	Exponentiation	2	N
*	Multiplication	3	N
/	Division	3	N
%	Modulus/Remainder	3	N
+	Addition	4	N,C,D
-	Subtraction	4	N,C,D

When dealing with Character data types, the operators have the following definitions:

Operator	Operation
+	Concatenate the right hand string to the end of the left hand string
-	Concatenate the right hand string to the end of the left hand string after trimming the left hand string of trailing spaces

? 2*3^2
        18
? 2*25%7
      1.00
? [Hello     ] - [ World]
Hello World
