These are my solutions that I submitted to Stanford University Mathematics Camp and Canada/USA Mathcamp for the summer of 2026. I was accepted to both programs as an international student. The Canada/USA Mathcamp quiz can be found here: https://www.mathcamp.org/qualifying_quiz/current_quiz/ Let me know if there are any mistakes in these solutions, that would really be appreciated!
