Syntax

+ cast-expression
- cast-expression
add-expression + multiplicative-expression
add-expression - multiplicative-expression
multiplicative-expression * cast-expression
multiplicative-expression / cast-expression
multiplicative-expression % cast-expression
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.

% (modulus operator) returns the remainder of integer division and cannot be used with floating points.

++ (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.
