Basic operations

Like all other programming languages, Ruby comes packed with a whole bunch of operators.

Arithmetic operators

Assume a = 2 and b = 4.

Operator	Description	Example
+	Addition: Adds values on either side of the operator	a + b will give 6
-	Subtraction: Subtracts the right-hand side operand from the left-hand side operand	a – b will give -2
*	Multiplication: Multiplies values on either side of the operator	a * b will give 8
/	Division: Divides the left-hand side operand by the right-hand side operand	b / a will give 2
%	Modulus: Divides the left-hand side operand by the right-hand side operand and returns the remainder	b % a will give 0
**	Exponent: Performs exponential (power) calculations on operators	a ** b will ...
