# Math Rounds

## Functionality
Our application will give an opportunity to authorizated users to compete in _rounds_ --- math competitions. To participate in a competition user must register for it and solve problems at a specific time. Every problem has one or more correct answers. After time is up, last answer for every problem is submitted. Then answers are checked for the correctness. After all submissions are tested, a table with results of all users will appear. Every user has their rating which is updated after every round depending on their result. Also users can participate in finished rounds at any moment, but their rating will not change.

Rounds are created by editors from among ordinary users. To do that user must provide a statement and a set of all correct answers for every problem. For creating rounds users will increase their social rating.
