+## 📚 Advanced Usage Examples
+
+### Complex Mathematical Reasoning
+```
+Input: "A projectile is launched at 45° with initial velocity 50 m/s. Calculate the maximum height, range, and time of flight. Use g = 9.8 m/s²."
+
+Expected: Detailed physics solution with kinematic equations
+```
+
+### Multi-step Algebra
+```
+Input: "Solve the system of equations: 2x + 3y - z = 7, x - 2y + 4z = -3, 3x + y + 2z = 10"
+
+Expected: Systematic solution using elimination or substitution
+```

+
+Expected: Step-by-step integration with proper setup
+```
+
+---
+
+## 🔍 Quality Comparison Test
+
+Test the imatrix advantage with this challenging problem:
+
+```
+Prompt: "A cylindrical tank with radius 3m and height 8m is filled with water to 75% capacity. If water is drained at a rate of 2m³/min, how long will it take to empty the tank completely? Also calculate the water level after 30 minutes of draining."
+
+Expected Results:
+- Initial volume calculation: π × 3² × 8 × 0.75 = 54π m³
+- Time to empty: 27π minutes ≈ 84.8 minutes  
+- Water level after 30 min: ~4.4 meters
+
+Imatrix models should show cleaner reasoning and more accurate intermediate steps!
