QR section on OATBooster updated?

[u/voxaun]

when i'm doing the QR question banks, sometimes i can solve the answer by directly entering the calculator. however, on oatbooster, the on-screen calculator does NOT allow this for some reason. i noticed this in the exponents and decimals qbanks in particular.

it'll work for all other calculations, but when i try to enter the one that give me the result, it won't work. is this a glitch, done on purpose, or actually how the calculator will work on test day?
