Derivation

  1. Initial program 0.1

    \[\left(\frac{m \cdot \left(1 - m\right)}{v} - 1\right) \cdot \left(1 - m\right)\]
  2. Using strategy rm

  3. Applied sub-neg0.1

    \[\leadsto \left(\frac{m \cdot \color{blue}{\left(1 + \left(-m\right)\right)}}{v} - 1\right) \cdot \left(1 - m\right)\]

  4. Applied distribute-rgt-in0.1

    \[\leadsto \left(\frac{\color{blue}{1 \cdot m + \left(-m\right) \cdot m}}{v} - 1\right) \cdot \left(1 - m\right)\]
  5. Using strategy rm

  6. Applied sub-neg0.1

    \[\leadsto \left(\frac{1 \cdot m + \left(-m\right) \cdot m}{v} - 1\right) \cdot \color{blue}{\left(1 + \left(-m\right)\right)}\]

  7. Applied distribute-rgt-in0.1

    \[\leadsto \color{blue}{1 \cdot \left(\frac{1 \cdot m + \left(-m\right) \cdot m}{v} - 1\right) + \left(-m\right) \cdot \left(\frac{1 \cdot m + \left(-m\right) \cdot m}{v} - 1\right)}\]

  8. Simplified0.1

    \[\leadsto 1 \cdot \left(\frac{1 \cdot m + \left(-m\right) \cdot m}{v} - 1\right) + \color{blue}{\left(m - \frac{m}{v} \cdot \left(m - m \cdot m\right)\right)}\]

  9. Final simplification0.1

    \[\leadsto \left(m - \left(m - m \cdot m\right) \cdot \frac{m}{v}\right) + \left(\frac{m + \left(-m \cdot m\right)}{v} - 1\right)\]
