Show HN: Lathoa, a math app for kids where the AI is wrong on purpose

A robot called Errol solves a math problem step by step and one of the steps is wrong.

Key points

  • I made this for kids around 10 to 14.
  • The user needs to enter an explanation if she finds an error to gain more XP; speed matters also for more points.
  • The arithmetic check is there for that, but it only works on English cases so far.
  • What I'd really like to know: does finding someone else's mistake teach anything that solving the problem yourself doesn't?
