title: How to Substract two numbers with positive result without using if else and any built-in methods to check which number is greater in python
body: <p>Is there is any way to substract two numbers without using if else and return always positive right result.
  Note: we are considering that we have to substract smaller one from larger one always. But user can enter the value in any sequence so we have to check that which num is greater. But we are restricted to use any builtin method and if else for that.
  ex :  input value = 5-10 = -5
  but we have to do 10 - 5 without using if else and built- in methods to find which number is greater to substract larger from smaller.</p>
