FAQ
How do I use keyboard input?
Click the calculator first, then type numbers and operators. Enter or = evaluates, Escape or C clears, Backspace deletes the last character. Use ( and ) for parentheses.
What does the ANS button do?
ANS inserts the result of your last calculation, letting you chain operations — for example: calculate 25², press =, then press ANS + 10 to add 10 to the previous answer.
How does the xʸ (power) button work?
Type a base number, press xʸ, then type the exponent, then press =. For example: 2 → xʸ → 8 → = gives 256.
What is EE (scientific notation)?
EE inserts ×10^ so you can enter numbers in scientific notation. For example: 1 EE 6 enters 1×10⁶ = 1,000,000.
