Example output structure:

{
  "detailed_steps": [
    {
      "step": "Original equation: x² + 2x - 3 = 0",
      "explanation": "Starting with the given equation"
    },
    {
      "step": "This is a quadratic equation (degree 2)",
      "explanation": "Applying the quadratic formula to find solutions"
    },
    ...
  ]
}

2. Beautiful Visual Design

  • Modern dark theme
  • Gradient accents
  • Smooth transitions
  • Card-based layout
  • Responsive across devices

3. Complete Full-Stack Architecture
