## Project-Specific Instructions

## Analysis Document Update - 2025-09-25 07:00:00

This section updates the analysis document based on the user prompt and the revised project breakdown.

### Project Overview Update
The project goal is to develop a simple calculator application.  Based on the `io8codermaster` breakdown, a backend is not required for this project.

### User Requirements Update
The user requires a functional calculator application that performs basic arithmetic operations (+, -, *, /).  Error handling, such as division by zero, is a critical requirement.

### Functional Requirements Update
The following functional requirements have been identified:

* **FR-001: Perform Addition:** The calculator shall correctly add two numbers.
* **FR-002: Perform Subtraction:** The calculator shall correctly subtract two numbers.
* **FR-003: Perform Multiplication:** The calculator shall correctly multiply two numbers.
* **FR-004: Perform Division:** The calculator shall correctly divide two numbers.  It shall handle division by zero gracefully, displaying an appropriate error message.
* **FR-005: Handle User Input:** The calculator shall accept numerical input from the user via buttons.
* **FR-006: Display Results:** The calculator shall display the results of calculations clearly to the user.

### Non-Functional Requirements Update

* **NFR-001: Usability:** The calculator shall be intuitive and easy to use.
* **NFR-002: Responsiveness:** The calculator shall be responsive and work seamlessly across various devices and browsers.
* **NFR-003: Performance:** The calculator shall provide quick calculation results with minimal latency.

### User Stories Update

* **US-001:** As a user, I want to be able to add two numbers together so that I can perform basic arithmetic.
* **US-002:** As a user, I want to be able to subtract two numbers so that I can perform basic arithmetic.
* **US-003:** As a user, I want to be able to multiply two numbers so that I can perform basic arithmetic.
* **US-004:** As a user, I want to be able to divide two numbers so that I can perform basic arithmetic.  I expect an appropriate error message if I try to divide by zero.
* **US-005:** As a user, I want a clear display showing the result of my calculations.

### Business Rules Update
No specific business rules apply to this simple calculator application.
