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 *-un-lft-identity0.1

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

4. Applied associate-*r*0.1

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

5. Applied simplify0.1

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