Syntax

+ cast-expression
- cast-expression
add-expression + multiplicative-expression
add-expression - multiplicative-expression
multiplicative-expr * cast-expr
multiplicative-expr / cast-expr
multiplicative-expr % cast-expr
postfix-expression ++       (postincrement)
++ unary-expression         (preincrement)
postfix-expression --       (postdecrement)
-- unary-expression         (predecrement)

Remarks 

Use the arithmetic operators to perform mathematical computations.  

The unary expressions of + and - assign a positive or negative value to the cast-expression. 

• (addition), - (subtraction), * (multiplication), and / (division) perform their basic algebraic arithmetic on all data types, integer and floating point. 

++ (increment) adds one to the value of the expression. Postincrement adds one to the value of the expression after it evaluates; while preincrement adds one before it evaluates. 

-- (decrement) subtracts one from the value of the expression. Postdecrement subtracts one from the value of the expression after it evaluates; while predecrement subtracts one before it evaluates.
