i’m an idiot for just now starting to use my BAII plus. i’ve been using the TI 83 out of habit.
and, wouldn’t you know it, i can’t get the BAII plus to show me more than a few digits.
Is there some simple button (maybe sigfigs) that i need to press to fix this so that 5.89 x 12.36 doesn’t just give me 60?
thanks.
