FAQ

Common Questions

Common questions regarding keyboard support, clear keys, and calculation histories.

Does this calculator support order of operations?
Yes. While designed for simple calculations, the internal engine evaluates simple multi-operator expressions using basic algebraic rules (multiplication and division before addition and subtraction).
Can I use my computer's keyboard to type numbers?
Yes. The calculator maps standard keyboard buttons, allowing you to use your physical numeric keypad, backspace, enter, and operator keys directly.
What do the 'C' and 'AC' buttons do?
The 'C' (Clear) key deletes the last number or operator typed. The 'AC' (All Clear) key resets the entire calculator memory and sets the active display back to zero.
Can I calculate negative numbers?
Yes. Use the toggle sign key (+/-) to switch the active number between positive and negative values.
Are my numbers uploaded or tracked?
No. The simple calculator runs completely client-side in your local web browser. Your inputs and equations are never sent to external databases.
