Derivation

  1. Initial program 0.0

    \[500 \cdot \left(x - y\right)\]
  2. Using strategy rm

  3. Applied sub-neg_binary640.0

    \[\leadsto 500 \cdot \color{blue}{\left(x + \left(-y\right)\right)}\]

  4. Applied distribute-rgt-in_binary640.0

    \[\leadsto \color{blue}{x \cdot 500 + \left(-y\right) \cdot 500}\]

  5. Simplified0.0

    \[\leadsto \color{blue}{500 \cdot x} + \left(-y\right) \cdot 500\]

  6. Simplified0.0

    \[\leadsto 500 \cdot x + \color{blue}{y \cdot -500}\]

  7. Final simplification0.0

    \[\leadsto 500 \cdot x + y \cdot -500\]
