Mental Math for Trading Interviews - MentalMath.online

Hey all!

When I was preparing myself for trading interviews, I had to code a script to generate math equations as tradertest(dot)org was no longer with us. Now I've made a website out of it for other people to use - mentalmath(dot)online.

At this point it's a beta version, I'd be glad to hear any feedback. I think the easy difficulty now is representative of the difficulty I encountered in various firms (Optiver, Akuna). Hope you like it.
