java Arithmetic Operators

The result of arithmetic operators is double if either operand is double, else float if either operand is float, else long if either operand is long, else int.
++i	Add 1 to i before using the value in the current expression
--i	As above for subtraction
i++	Add 1 to i after using the value in the current expression
i--	As above for subtraction
n + m	Addition. Eg 7+5 is 12, 3 + 0.14 is 3.14
n - m	Subtraction
n * m	Multiplication. Eg 3 * 6 is 18
n / m	Division. Eg 3.0 / 2 is 1.5 , 3 / 2 is 1
n % m	Remainder (Mod) after division of n by m. Eg 7 % 3 is 1
