Simple problems resolved

Good morning!

I added the files with the solutions.
They were created in Visual Studio 2010.

Here is a print screen of the VS Solution if you want to reproduce it:

The UnitTests project needs a reference to the SimpleProblems project.

Thank you for your time.
I wanted to have not to few and not to many comments but I guess I shoot over the top. Thanks for the link.
