Welcome to Jacobs Math Study Group - Part 2.
Due to some technical difficulties I had to change the address of my Math Endeavor blog. I now call it Jacobs Math Study Group - Part 2. The new address is jacobsmath.bogspot.com. You can still find these previous entries: Number Guessing Trick Dr. Spock Clock Gauss's Challenge The Famous Jinx Puzzle at the old blog site.
