… of between the ancient mathematicians, which more has influenced me has been Euler, principally because Euler did something that no other mathematician of his size did. He told how he obtained his results, and I am deeply interested in this. And com has to do my interest to solve problems.

George Polya, route Division by Zero.
The Hungarian mathematician Polya pronounced this phrase in an interview that did to him in his ninetieth anniversary (90 years) and that can be in The Two-Year College Mathematics Journal, Vol. 10, No. 1 (Seed drill., 1979), pp. 13-19.
The truth is that I cannot agree any more with Polya, since, at least in my classes, I try to teach my pupils to solve all kinds of problems, and not to that two or three are learned of memory. More important comprehension is the process and to apply it well, that to realize the calculations correctly and to hand (at least in an examination).
And you? what do you think?
