PringlesMaths

I'm a British engineering student with several years of competition mathematics experience, including the British Mathematical Olympiad, the British Physics Olympiad, and various university admissions tests. PringlesMaths started as a way to stay mathematically sharp — and turned into something I didn't expect.

Each week I post four problems sourced from olympiads, integration bees, and competition mathematics worldwide, with full LaTeX-typeset solutions — every step written out, every source cited. The account has grown to a community of over 13,000 followers who take competition mathematics seriously. I post because I believe elegant mathematics deserves to be written down properly.
