Modular arithmetic, even when disguised as a rounding problem, can be just as simple, if not simpler. The technique discussed here works for any constant N , delivers solutions even when x has 32 or ...

One of my fellow contributors here recently wrote a post about leap years and why we have them. This reminded me of modular arithmetic and the formula for calculating the day of the week for any ...

They were using a small transformer — a network architecture that’s recently revolutionized large language models — to do different kinds of modular arithmetic, in which you work with a limited set ...

By extending the scope of a key insight behind Fermat’s Last Theorem, four mathematicians have made great strides toward ...
