Derivation

1. Initial program 85.8%

   \[x + \frac{y \cdot \left(z - t\right)}{a - t} \]
2. Add Preprocessing

3. Taylor expanded in t around inf

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

   1. +-commutative N/A

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

   2. lower-+.f64 61.8

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

5. Applied rewrites 61.8%

   \[\leadsto \color{blue}{y + x} \]
6. Add Preprocessing
