I've done RLF twice, and the main time waster has been this room. And due to the conflicting experiences, I'm not sure how exactly one should go about it.
First time, I did the math problems three times, called me a dummy for getting them right, then said she ran out of questions, and let me pass.
Second time, I just put 0, she still called me a dummy, so I just did that a bunch of times, wasn't letting me pass, then I started doing the problems, got one for which the correct answer is above 3000, which it won't let me enter a number higher than, then just resorted to answering 0 a bunch of times because I was running out of time, and then she let me pass.
So, what exactly is the goal? Just keep on giving her answers, whether they're right or wrong, until she lets me pass? Or do correct answers help it go faster?
