  3. Do you know of a way to create a unique 5-digit number out of a unique combination of two 5-digit numbers? for instance if the number A = 100 and number B = 20, what I did to get the unique number was simply add them and get 120. however, this is not unique since a separate combination such as 99 and 21 will give me the same number… any suggestions on creating a unique number from a unique set of numbers?
