    YOU don't...not if you have this. Come to think of it, I would not have needed my calculus tutor if I'd had this.

    I use this app for all of my calculations. It is quite versatile an complete. I bought the ads free version for more convenience. My only complaint is that it vanishes from my home screen every time after an update. It's an annoying quirk, but I can live with it. I highly recommend it.

    The slash should preceded and followed with a space during "fraction mode" input.

    Love my calculator app! Best money I've spent on an app. The only thing I've ever tried to throw at it that it wouldn't do is a full amortization schedule - would love to see that added even though it's a bit overkill for a calculator.
