Building a cryptex led me to maths toys, prompting the question: what if I combined them? The outcome was a cryptex that only unlocks when a mathematical equation is correctly solved. This innovative design features an X ring with numbers, a function ring filled with operators, a Y ring, an equals ring, and a Z ring. To access its secrets, you must create a simple arithmetic expression using the rings. The numbers on the X, Y, and Z rings have been carefully chosen to help users find the solution in just a few steps.
