They tackle the tough stuff: explainers of four dimensional shape making, quaternions, the largest prime number ever recorded on paper. This week, they dissected how to break down a cake amongst three.

In the video's hypothetical, we follow Alice, Bob, and Charlie, three generous and egalitarian friends who seek to divide a recently acquired cake equally. The division process explained in the video feels arbitrary and unnecessarily complicated, but isn’t that just all math? Nonetheless, the narrator effectively explains how to divide what seems like a dry and crumbly cake into three even portions:

So, time to put this knowledge to good use: bake a cake and call up two friends! We have just the recipes to get you started:
