Derivation

1. Initial program 12.2

   \[\left(\left(3 + \frac{2}{r \cdot r}\right) - \frac{\left(0.125 \cdot \left(3 - 2 \cdot v\right)\right) \cdot \left(\left(\left(w \cdot w\right) \cdot r\right) \cdot r\right)}{1 - v}\right) - 4.5\]

2. Initial simplification0.4

   \[\leadsto \left(\left(3 + \frac{2}{r \cdot r}\right) - 4.5\right) - \frac{\left(-2 \cdot v + 3\right) \cdot 0.125}{\frac{1 - v}{\left(w \cdot r\right) \cdot \left(w \cdot r\right)}}\]
3. Using strategy rm

4. Applied associate-/r*0.3

   \[\leadsto \left(\left(3 + \frac{2}{r \cdot r}\right) - 4.5\right) - \frac{\left(-2 \cdot v + 3\right) \cdot 0.125}{\color{blue}{\frac{\frac{1 - v}{w \cdot r}}{w \cdot r}}}\]
5. Using strategy rm

6. Applied associate-/r/0.3

   \[\leadsto \left(\left(3 + \frac{2}{r \cdot r}\right) - 4.5\right) - \color{blue}{\frac{\left(-2 \cdot v + 3\right) \cdot 0.125}{\frac{1 - v}{w \cdot r}} \cdot \left(w \cdot r\right)}\]

7. Final simplification0.3

   \[\leadsto \left(\left(3 + \frac{2}{r \cdot r}\right) - 4.5\right) - \left(r \cdot w\right) \cdot \frac{\left(3 + v \cdot -2\right) \cdot 0.125}{\frac{1 - v}{r \cdot w}}\]
