Incorrect Calculation?
Almost Perfect
Please fix calculus. Some of the answers require infinity, and this is not allowed in the answers. For example, I recently got the question: Given h(x) = 8/x find h’(0). The answer is -∞ as this is the limit from the left and right hand sides, but this is impossible to enter with the ‘Differential Departments’ keyboard.
One possible stopgap solution would be to make the correct answers available if you pay for a skip (with in-game currency), this way we users can figure out what the game wants in such strange situations. Alternatively, you could take away the questions generating these issues, possibly by plugging all differentiation questions into the Wolfram engine to check the outcomes and then deleting the ones that don’t match. Of course, this won’t work if the questions are auto generated and not drawn from a bank —unless you run all possible questions (which would probably take a long time).
Love it, want more!

Wow thank you for the amazing review! It is awesome to see that the app is appealing even for such a high level of math! Those modes would be great to see in the app one day.
Wonderful math app!!

Thank you so much for the kind words! I’m glad to see that the focus on making the experience rewarding worked out. I do agree that having a little “manual” for tricks to do the mental math faster would definitely enrich the experience.
Beware!

These are just ways to help add progressiom to the game. Everything aspect of the game is FREE to play. By solving problems you get in game money to then purchase the different towns. This helps players build up so they aren’t overwhelmed . Sorry for the misunderstanding! When developing I thought it might add confusion by making the in game currency represented by $ but I thought this symbol would be easiest to understand. However there is an in app purchase which deletes adds that also uses that symbol but I do add a reminder at the the top this uses real money. Maybe in the future I could add a warning at the beginning of the claim to clarify that. I appreciate you downloading the app and giving it a try!
