Classes error

I keep getting the following error when running the script created in the lesson about classes: unbound method multiplication() must be called with calculator_1 instance as first argument (got int instance instead)

Here is the code that I'm using:

class calculator:
	
	def addition (x, y):
		added = x + y
		print added

	def substraction (x, y):
		sub = x - y
		print sub

	def multiplication(x, y):
		mult = x * y
		print mult

	def division(x, y):
		div = x / y
		print div


calculator.multiplication(3, 5)
