George Pólya's 1945 book How to Solve It, A new
aspect of Mathematical Method, is a book describing methods of problem
solving. It suggests the following steps when solving a mathematical problem:

First, you have to understand the
problem.

After understanding, then make a
plan.

Carry out the plan.

Look back on your work. How could it
be better?
Polya's work has had a large influence
on mathematics textbooks. "Most formulations of a problem solving
framework in U. S. textbooks attribute some relationship to Polya's
problem solving stages (1945)."
