Show HN: A tool for kids to practice arithmetic

Cool! Wishlist if you’re looking for new features:

- A way to skip to higher level at the start—like maybe an Easy, Normal, Hard difficulty level like in video games.

- CSS themes to make it aesthetically neater. Like a ninja background image, you-got-it-correct animated elements, etc.

But yeah, cool hobby project for sure.

Thanks. Great ideas.

I am actually building it for my son to practise, so hopefully I will work on this for a while.
