The proof was never written down, so the challenge has been to rediscover the proof of Fermat's Last Theorem ... into the night studying the works of Euler and Newton. But this sudden interest ...

Now, a team of mathematicians led by a prominent Kyoto University professor has offered an alternative proof to Fermat's Last Theorem, the potential second solution in the past quarter-century.

In this module we study intergers, primes and equations. Topics covered include linear and quadratic congruences, Fermat Little Theorem and Euler's Theorem, the RSA cryptosystem, Quadratic Reciprocity ...
