What is Fermat's last theorem?

Fermat's law means that there is no nonzero integer solution to the equation A 3+B 3 = C 3, A, B and C. This conjecture was first put forward by Fermat, so it is called Fermat's last theorem. Fermat was an amateur mathematician at the beginning of17th century. His job is a lawyer, which was found in his notes. He claimed to have thought of a clever way to prove this theorem, but people didn't find the manuscript he proved. This problem has puzzled mankind for nearly 300 years, and it was not proved until recently. Moreover, this proof is quite long, and it is said that mathematicians may not all understand it. This person has been to Peking University to give a speech recently. My name is wiles.
