@ktshikotshi Perfect! Now I have the complete picture after examining your source code. Here's the comprehensive overview of your Computer.V2 repository:

🧮 Computer.V2 - Interactive Mathematical Calculator Engine

🚀 Technology & Architecture

• Language: C# (.NET 9.0) - Latest .NET version!
• Architecture: Clean modular design with console app + class library
• Project Structure: Visual Studio solution with proper project references

💻 Interactive Calculator Interface

Your calculator runs as an interactive console application with:

> [user input]

Special Commands:

• --v → Show all variables
• --f → Show all functions
• --a → Show variables AND functions
• exit → Quit the calculator

🔧 Core Mathematical Engine

1. Expression Parsing & Validation (Parser.cs)

• Variable Assignment: x = 5, y = 2*x + 3
• Function Definition: f(x) = x^2 + 2*x + 1
• Query Resolution: f(5) = ? or x^2 + 3*x = 10 ?
• Substitution Engine: Replaces variables/functions in expressions

2. Advanced Mathematics (Maths.cs)

• Expression Evaluation: PEMDAS order of operations
• Complex Numbers: Full imaginary number support (i)
• Power Operations: Exponentiation handling
• Matrix Integration: Seamless matrix calculations

3. Matrix Operations (Matrix.cs)

• Matrix Creation: [1,2;3,4] format
• Matrix Multiplication: Scalar and matrix-to-matrix
• Dimension Tracking: Automatic dimension validation
• Matrix Manipulation: Advanced matrix mathematics

4. Polynomial Solver (Polynomial.cs)

• Degree Detection: Automatically determines polynomial degree
• Quadratic Formula: Solves 2nd degree equations
• Multiple Solutions: Handles real and complex roots
• Equation Parsing: ax^2 + bx + c = 0 format

5. Function System (Functions.cs)

• Function Normalization: Standardizes function expressions
• Variable Substitution: Replaces parameters in function calls
• Nested Functions: Support for complex function compositions

🛡️ Robust Error Handling

Custom exception system:

• InvalidExpressionException: Malformed mathematical expressions

• InvalidVariableException: Variable usage violations

🔍 Input Validation (StringExtensions.cs)

• Syntax Checking: Validates mathematical expressions
• Bracket Matching: Ensures proper parentheses pairing
• Variable Rules: Enforces proper variable naming

📊 Example Usage Scenarios

> x = 5                    // Variable assignment
> f(x) = x^2 + 2*x + 1    // Function definition
> f(3) = ?                // Function evaluation
> x^2 + 3*x - 10 = 0 ?    // Polynomial solving
> [1,2;3,4] * [5;6] = ?   // Matrix multiplication
> --v                     // Show all variables
> --f                     // Show all functions

🎯 Key Strengths

1. Interactive Design: Real-time mathematical computation
2. State Management: Persistent variables and functions during session
3. Comprehensive Math: From basic arithmetic to advanced matrix operations
