Malcolm in the Middle episode where he memorizes credit card numbers?

Question

I used to watch Malcolm in the Middle all of the time and my favorite episode was one where Malcolm memorized a couple of credit card numbers for a talent show or competition, then multiplied and divided the large numbers from memory. Anyone know the name of that episode? Thanks...
