I have noticed that you can add an international keyboard in settings that allows easy typing in foreign languages within any application. Has anyone seen a math and science keyboard that can be added to the list of international keyboard choices? I need to be able to take notes in chemistry class with the ability to have subscripts, charges, reaction arrows, etc.

I want to type 2KClO3 --> 2KCl + 3O2 and have it look nice.

Also, what if I need the integral sign used in calculus.

Thanks

Try OLNCloud, where it is much easier to draw chemical structures, and it automatically generating formulas.
