One of the five keyboards, showing an expression being entered. The other keyboards contain more functions, hexadecimal digits and variable names. Notice the red Fn button. By tapping this button the function selector pops up.

This is the results screen. The expressions in this example show only a small fraction fo the available functions. All items are interactive. By tapping on an epression you are taken back to the keyboard view and can alter the expression.

The results screen can also display function plots. You can pan and zoom them, or double tap to make them full screen.

In full screen mode you have the option to save the image to the camera roll.

Some more functions. Note that you can assign any expression to a variable and use that variable in future expressions.
