So true, Ed. Do you have any suggestions on how to show other people how to do math the way you do?

I'm not a math guy but I can do calculation pretty quickly in my head, precisely by doing things like this. Learning to see numbers as groups, not to follow plodding and mechanical methods forced on you in grade school.

Ken never multiplies.  He's a mathematician.
