Needs some work

As of version 1.1.0, this app is pretty flawed.

You cant copy or paste numbers. Theres no button to clear the tape.

Worst of all, common sense operations dont work the way they should. For example, if you type the following: "10+1" on any normal calculator, youll get 11. On this calculator, you get 10. If you do the same operation with minus instead of plus (10-1) you get the maddening answer "-10".

This calculator needs a fair bit of polish before theyre ready to charge money for it.
