Calculator panels
Two calculator’s panels are available: basic and advanced. Use
the Basic panel to enter numbers and perform basic addition,
subtraction, multiplication, and division. Use the Advanced
panel to insert advanced operators or delimiters, such as sine,
cosine, tangent, square root, parentheses, etc.
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 flashes red to let you
know the selection was made. Make sure you see the red flash
before entering your next number or completing the operation.
To delete numbers, one at a time, touch CLEAR on the screen.
To clear your operation history, press MENU and select ‘Clear
history’.
