At first, it was a little tedious to figure out the inputs and the right calculations to get the correct answer, but like all new things, with enough practice and getting around that learning curve, it became second nature

But when I used it to calculate PV, PMT, and FV, the result were different from the right answers a lot

and it's now giving me the wrong answers

It keeps giving me the right answers.

Your answer is all wrong or you get an error message

HP is an amazing calculator except thatbyou need to clear it all every transaction because it may give you incorrect answers sometimes!

I did not receive the instruction manual for this calculator and couldn't figure out why it kept giving wrong answers

This calculator was throwing out wrong answers then the one I originally have in my textbook

Kept giving me the wrong answers
