    1. Started with
      \[x + \frac{y - z}{\left(t + 1.0\right) - z} \cdot \left(a - x\right)\]
      0.9
    2. Applied simplify to get
      \[\color{red}{x + \frac{y - z}{\left(t + 1.0\right) - z} \cdot \left(a - x\right)} \leadsto \color{blue}{(\left(a - x\right) * \left(\frac{y - z}{\left(1.0 + t\right) - z}\right) + x)_*}\]
      0.9
    3. Using strategy rm
      0.9
    4. Applied fma-udef to get
      \[\color{red}{(\left(a - x\right) * \left(\frac{y - z}{\left(1.0 + t\right) - z}\right) + x)_*} \leadsto \color{blue}{\left(a - x\right) \cdot \frac{y - z}{\left(1.0 + t\right) - z} + x}\]

    5. Using strategy rm
      0.9
    6. Applied pow1 to get
