The Ramanujan algorithm, which will generate "pi" out to several hundred decimal places...

Avoid having your brain trick you, by adding all the thousands first, then adding all the tens.

Tried it twice, got 4100 each time.

The second one is so simple. If you work it out in algebraic terms, it basically comes out to 100x + (2003 - year born), where x is the number you picked. And you either use 2002 or 2003 depending on whether you've had your birthday yet. So, 2003-year born is your age, obviously. Multiply some digit by 100 and add it to your age, you get a 3-digit number that starts with that digit and ends in your age. No magic here. Been seeing these for years. The 1752/1753 you add on keeps going up every year.
