How'd They Do This?

I'm sure there's a logical mathematical explanation here. But I haven't figured it out yet. Let me know if you have any luck with it.

Also, in an unrelated matter, check out this blog. It's always flattering when a complete stranger likes your work enough to post it on their own site.

How'd they do this????? Urgh, when mom sent it to me I was so frustraterd, then I thought I figured it out when the computer got my answer wrong once. ONly it got it right every time after that like 10x. I quit.

Somehow, when you add the digits and subtract them, you generate a multiple of 9. Then if you look at the chart, all the multiples of nine are the same symbol, the chosen one.
