Description

* Intuitive column layout displaying multiple equations on the same screen
* Ability to modify operands and operators at any time
* Linked numbers that calculate interactively in real-time

The calculator's display and operation have been redesigned from the ground up.

Calculator Features:

- Multi-line Display:
Equations are clearly displayed line by line, with the length of numbers and operators automatically adjusted to fit the screen width.

- Equation Modification:
Freely select and change numbers within equations. Operators can also be modified to alter the results.

- Linking and Interaction:
Numbers in links update interactively. A single number can be linked to multiple numbers.

- Theme Selection:
Choose from white, black, brown, and more than three different theme colors.

- Delete Functions:
"AC" for full clear, erasing the entire calculator screen.
"R" for line clear, removing one line from the list.
"C" for clear, resetting a number to zero.
"BS" for backspace, deleting the previous input.

- Lock Feature:
Replaces traditional memory functions with a more intuitive lock feature. Protect numbers you don't want to delete with a single button lock.

- Save Previous Equations:
Even if you restart your device, leave the application unopened for an extended period, or switch between applications, previous equations will be saved.
