It is helpful for anyone who wants to learn operations on integers. My only issue is that some questions have only one possible answer to choose from and it is almost always the correct one. I hope you can fix it. God bless.

Thanks for letting us know 🙏🏼🙏🏼. We're planning a major upgrade beginning next year, and we'll make sure to have it addressed in that version.

why do i NEED to get "stars" on previous levels to try the next one? So if I try math that is too hard for me, am I going to hurt myself? Or destroy the universe? Poor! Also, when the phone autorotates, the app starts spazzing out. Just....poor.

Certainly will not destroy the universe, but some aliens will come knocking your door at 5am then asking you the reason of skipping levels.
BTW, thx for the info that the application is spazzing out when phone autorotates. Will check ASAP.
