Each of the two pads is a fully independent four-function calculator with its own memory — nothing you type or calculate on one pad affects the other until you explicitly move a value between them.
The copy, paste, and drag actions send only the displayed number from one pad to the other, letting you chain a result into a new calculation without retyping it by hand — useful for running two related figures side by side, like a subtotal on one pad feeding into a tax calculation on the other.
The two pads don't share a pending operator or any in-progress calculation state — only the final displayed value ever moves between them, so each pad's own math stays self-contained and easy to follow.
It's useful for comparing two figures side by side, or running a calculation on one pad and feeding its result into a separate calculation on the other — like working out a discount on one pad and applying it to a running total on the other.
Use the copy, paste, or drag action to send the currently displayed number from one pad to the other. Only the final number moves, not any in-progress operation.
No — each pad is a fully independent four-function calculator with its own memory and pending operator. They're only connected through the manual copy/paste/drag action.
Each pad responds to keyboard input based on which one is currently focused — click into the pad you want to type on first.
