Thank you so much for creating this. The tutorial sections are clear, concise, and intuitive. The testing section is wonderful for practicing what you have learned. I wanted to let you know how impressed I was by the first few iterations you have released. Great work so far. I really hope you decide to continue working on this. You might just be training the next Euler!

Good, but doesn’t give all the necessary information

This app is well made. However, it doesn’t give enough information. How do I multiple by 3 digit 11’s and turn it into a 4 digit number? Not sure!
