Derivation

  1. Split input into 2 regimes

  2. if (* y z) < 9.523507907051805e+193

    1. Initial program 2.0

      \[x \cdot \left(1 - y \cdot z\right)\]
    2. Using strategy rm

    3. Applied sub-neg2.0

      \[\leadsto x \cdot \color{blue}{\left(1 + \left(-y \cdot z\right)\right)}\]

    4. Applied distribute-rgt-in2.0

      \[\leadsto \color{blue}{1 \cdot x + \left(-y \cdot z\right) \cdot x}\]
    5. Using strategy rm

    6. Applied distribute-rgt-out2.0

      \[\leadsto \color{blue}{x \cdot \left(1 + \left(-y \cdot z\right)\right)}\]

    7. Simplified2.0

      \[\leadsto x \cdot \color{blue}{\left(1 - z \cdot y\right)}\]
