CalABC app for iPhone and iPad

CalABC is not just a simple virtual calculator but an equation solver. That is, its designed to solve an entire equation consisting of a series of numbers and mathematical signs only when you tap the equal button instead of making a calculation every time you tap a sign like + and -. In this way, you can go back with the backspace button to correct a mistake when necessary.
