  • Subtraction: Two numbers can be added using the - operand:
       >>>456-123 
333
>>>123-456
-333
  • Multiplication: Two numbers can be multiplied as follows:
       >>>123*456 
56088
  • Division: Two numbers can be divided as follows:
       >>>456/22 
20.727272727272727
>>>456/2.0
228.0
>>>int(456/228)
