, designed as a rigorous preparation guide for Mathematical Olympiads (such as the RMO, INMO, and IMO) and first-semester undergraduate courses. Originally published in Portuguese, the English editions were released by Springer Nature between 2017 and 2018. www.researchgate.net Series Overview
While designed for university transition, the depth of the problem sets makes this a "top" choice for students preparing for high-level mathematics competitions (such as the International Mathematical Olympiad or the Putnam Competition). The focus on "proof techniques" and "hard problems" aligns perfectly with competitive math training. an excursion through elementary mathematics pdf top
