Derivation

1. Initial program 100.0%

   \[\left(x + y\right) \cdot \left(z + 1\right) \]
2. Add Preprocessing

3. Taylor expanded in z around 0 47.8%

   \[\leadsto \color{blue}{x + y} \]
4. Step-by-step derivation

   1. +-commutative 47.8%

      \[\leadsto \color{blue}{y + x} \]

5. Simplified 47.8%

   \[\leadsto \color{blue}{y + x} \]

6. Final simplification 47.8%

   \[\leadsto x + y \]
7. Add Preprocessing
