Q: Mobile web: numeric input + math operators I have HTML mobile web page containing form inputs.
I need to use NUMERIC keypad on android and iphone devices, but attribute type="number" doesnt look like right solution for me because it eliminates all numeric operations represented by "+" "-" "/" "*" 
So i need co combine numeric keypad on mobile devices and allow all math operators. How ?

A: Looks like iOS has the + key option but this leads to another sub-menu keyboard
iOS should popup this keyboard:
iOS Input type="number"

Android 2.2 should popup this keyboard (Other versions of Android may have different options):
Android 2.2 Input type="number"
