  1. Initial program 0.0

    \[500 \cdot \left(x - y\right)\]
  2. Using strategy rm
  3. Applied sub-neg_binary64_75730.0

    \[\leadsto 500 \cdot \color{blue}{\left(x + \left(-y\right)\right)}\]
  4. Applied distribute-rgt-in_binary64_75300.0

    \[\leadsto \color{blue}{x \cdot 500 + \left(-y\right) \cdot 500}\]
  5. Simplified0.0

    \[\leadsto \color{blue}{500 \cdot x} + \left(-y\right) \cdot 500\]
  6. Simplified0.0

    \[\leadsto 500 \cdot x + \color{blue}{-500 \cdot y}\]
  7. Final simplification0.0

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