Why are % and others hidden on iPad by default?

I really enjoy this calculator on the iPhone; however, in order to use the percentage sign on the iPad Pro (and Im assuming on other iPads as well), you have to expand a separate menu. Whereas on the iPhone the % and a few others are all part of the standard number pad.

Why is it that on a device with more real estate, you have to enable a menu that is typically hidden by default... But on the iPhone it isnt? Its odd...

The iPad app should be just as full-featured and intuitive as the iPhone equivalent, if not even more so.
