Timed mental arithmetic practice. This is a simple typescript app that you can use to practice mental arithmetic. Especially useful for those applying to quantitative trading jobs. I created it because I wanted more customizability for the problem generator than I was finding on other arithmetic trainers. I hoped to keep it extremely simple to use, but that goal conflicts somewhat with maximum customizability. This project is essentially complete I add a feature or two to this when I think of it and have time.
My progress running every street in Canberra. This project has ended (see details in the related post), and was interesting more for its physical challenge than its technical one. However, I intend to follow up with a new version that should be both more physically and technically challenging (and interesting). Stay tuned!
