There are card tricks which are slight of hand and card tricks which rely on the discrete mathematics inherent to a regular deck of cards. These card tricks fall into the latter category and are called self-working. Don’t worry, you do not need to understand discrete mathematics to learn the algorithm for performing these #MicDropMath card tricks. They wind up being a great way to get students practicing calculations in their heads regardless of how deep you dive into the mathematics behind why the tricks actually work. Enjoy!
