Math Fun
Joe, who works in the office next to mine, pointed out this neat math trick:
111,111,111 x 111,111,111 = 12,345,678,987,654,321
I noticed that the easy way to see this is to do the multiplication the way I learned in third grade:
111111111
x 111111111
---------
111111111
111111111
111111111
