JavaScript contains the standard arithmetic operators plus ones for modulus, increment, decrement and unary negation.
This is the modulus operator which returns the integer remainder of dividing the preceding operand by the one following it.
This is the standard multiplication operator and it returns the product of two numerical values (either literals or variables).
This is the standard addition operator and returns the sum of two numerical values (either literals or variables).
This is the increment operator and is used to increment (add one to) its operand.
This is the standard subtraction operator and it subtracts one number from another.
This is the decrement operator which decrements (deducts one from) its operand.
This is the standard division operator which divides one number by another.
