Oh no! You've forgotten your four-digit pin to unlock your bike, and you are running late for a class! However, six incorrect attempts locks your bike for good, and you REALLY don't want to have to run to your class! You've already used FIVE attempts- given some hints, and seeing the first five attempts, will you be able to plug in the correct pin on the last possible attempt? In this presentation, we will discuss the logic, problem solving, and reasoning it takes to get through this problem, all while audience members get to try it themselves!
