Welcome to Project Eureka!

Project Eureka is a collaboratively edited site for problem solvers/creators - regardless of problem or field.

We are a bunch of math enthusiasts who decided to create a website for submitting and solving problems.
However, project Eureka is not limited to math problems; any problem, puzzle, or trivia question can be submitted to project Eureka. Similarly, for people who prepare for various tests, project Eureka offers the possibility of grouping multiple problems in a test and simulate a standardized test environment.
