Math

I think I may have a new direction for this blog and I have Where’s George to thank for it. I was thinking about how the currency circulates and the exact nature of getting change. For those that don’t know, Where’s George is a Web site where people enter dollar bills that they get. The idea is to hope that someone else gets the same bill and enters it into the site, thus allowing both users to see where the bill has been and how far it has traveled.

I began thinking about how I have so many bills and how easy it really is to accumulate bills. Take, for instance, a $20 bill. If I enter that on the site, I have $20 listed. Now, take that twenty and use it to buy a lottery ticket for $1. That gives me $19 in change. Most likely, I’ll get a $10 bill, a $5 bill and four $1 bills. If I add those to the original $20, I get $39. The cumulative dollar value of what I have entered has almost doubled.

At this point, the $1 bills are useless in terms of my demonstration. The $10 and $5 bills, however, will get me another $5 bill and eight more $1 bills. (The ten is broken into a five and four ones and the five is simply broken into four ones.) That’s another $13. Added to the running total, that’s $52. After spending the remaining five on another lottery ticket, I get another $4, bringing me up to $56 off of the original twenty. Assuming I withdraw only twenties, my potential is almost three times whatever I withdraw.

This got me thinking. What if I were to do some sort of math-related blog? I suppose I could think up some strange mathematical curiosity to work out or something. It’s better than just sitting around waiting for something to happen. Comments? Suggestions?
