Keep up your "Laz Math". I love it! Math is supposed to be about concepts - not numbers, and you have alllllll kinds of concepts!
BTW, folks, I'm about to go to the donation thread and add the loose change that I've collected for the last 3 months. It came to $26.74, which I'll round out to $30.
I started this about a year ago. I was literally putting away one dollar/day for the "dollar/day" club, and decided to lighten my wallet of change. Not surprisingly, it added up - painlessly.
Try it -- you might like it!
