Very Useful This is a very good app for my math class. The only thing I can't get to work on my Galaxy S5 are the NOR and NAND functions. When I do the long hold on OR or AND, nothing happens.
Isn't allowing keyboard The app isn't allowing me to manually type in operators. Tried switching keyboards but still nothing. (SwiftKey to stock, then back)
Please help How to get table of more than one proposition at a time?
Great app! Very useful!
Nice! Precise and helpful.
