History
Keyboard works too — type digits and operators, Enter to evaluate, Backspace to delete, Escape to clear.
How it is calculated
Standard operator precedence: brackets, then powers, then × and ÷, then + and −.
Trigonometric functions accept degrees or radians — switch modes with the DEG/RAD key.
Worked example
Typing sin(30) in DEG mode gives 0.5. Typing 2^10 gives 1024. Typing √(144) + log(100) gives 14.
Questions people ask
Yes. Type numbers and operators directly, press Enter to evaluate, Backspace to delete and Escape to clear.
You are in radian mode. Press DEG to switch, and 30 will be read as degrees.
M+ adds the shown value to memory, MR recalls it into the expression and MC clears memory.
