Solve It is a new project from our department that aims to help undergraduate students test themselves and enhance their mathematical skills. We will regularly post some problems, and we will wait for a complete solution. The fastest delivered correct solution will be announced as the winner on this page. There will be a prize for the winner. The details of the prizes will be announced later. We encourage you to try to solve these problems even though you feel insecure about your solution because there may not be a submitted complete solution. Hence, the winner could be determined by a partial solution.
There is one method for submitting a solution: you can deliver your solutions to rooms R-201 or R-215.
Please remember that the audience of the problems will be undergraduate students from all levels. If you do not understand the problem or you think there is a mistake in the problem, then you do not need to hesitate to tell us.
Here, we published the Solve It 1.
