Simply type in "100+20%" to add taxes, or "100-30%" to easily calculate a discount. Inseries even shows you "pi" as a real constant instead of just a number. Inseries' clear user interface is designed for multitouch allowing us to come by with a small and simple keypad based on the clear keypad layouts of typical financial and business calculators. By using choosers for quickly accessing functions and constants we could bring in scientific calculator functionality without sacrificing usability.
