I really like how I can choose to control ads. Some of the calculating functions are not smoothly completed is why I held back on providing a 5. I like the look and menu options like sound, appearance, and history.

Just works simply & beautifully. Buttons are a good size to avoid mistyped entries & any errors can be erased one digit at a time. A running calculation & total tips off a great calculator.
