A Mathematical Puzzle Challenge for Archie

OK Archie. I'm going to try to challenge your powers of analysis to
see if you will be able to solve a puzzle. We'll take it one step at
a time. I'll present an instruction and will wait for confirmation
from you before I proceed to the next step. I realize this may drag
the problem out, but it's the only way I can be sure you don't cheat.
Looking at it from your perspective, that's a good thing for you - IF
you are able to provide the solution. Let's begin.

Step 1: Select two three-digit numbers that do not contain any of the
same digits (i.e., you can only use each digit from 0 to 9 one time).
You may use the zero as the leading (first) digit of one of the
numbers, but be sure to keep it on your paper as we will change the
order of the digits in an upcoming step.

Naturally, you should not tell me the numbers you select. Just let me
know when you have two numbers selected.

BTW - I freely admit that I was unable to solve the problem at first
and needed a major hint to get the answer.
