   I've seen this video a couple of times, but I never saw any explanation.... so I decided to work it out for myself how they did that! 🙂 Feel free to watch it and see if you can work it out yourself, but if you can't (or don't want to), then here's how this works (scroll down for reveal)...

   First some pronumerals, then the steps - a=97, b=94, c=3, d=6
   - c=100-a
   - d=100-b
   - the first 2 digits is a-d
   - the last 2 digits is cxd
