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 111111111 111111111 111111111 111111111 111111111 111111111 ----------------- 12345678987654321
