Sometimes the system tells me there are unexistent problems that go away when I repeat the exact same answer (stuff like "you should pass values in your function" when I'm already doing it), but right now I'm dealing with a calculation issue: the current challenge asks me to choose three numbers which, inside a certain formula (c* c* c+ a* b) make a number between 100 and 400.
Long story short, the numbers I choose return an error while using Firefox, and work fine when on Chrome.
That leads me to ask you: have you tested your challenges on Firefox?
This one error, being simple math, was quite obvious, but the other times I seriously questioned my code, which was actually right.
moderator: Going to instead first help out at your first question, as this may all be related, and then if needed help out with this one.
