Two calculator’s panels are available: basic and advanced. Use the Basic panel to enter numbers

insert advanced operators or delimiters, such as sine, cosine, tangent, square root, parentheses, etc.

panel’ or ‘Basic panel’, as you wish. As soon as you select an advanced operator, the panel
switches back to Basic, where your operator appears. When you touch a key on the screen, the key

entering your next number or completing the operation.
To delete numbers, one at a time, touch DELETE on the screen.
