Derivation

  1. Initial program 0.0

    \[\left(\left(x - \left(y - 1\right) \cdot z\right) - \left(t - 1\right) \cdot a\right) + \left(\left(y + t\right) - 2\right) \cdot b\]
  2. Using strategy rm

  3. Applied add-cube-cbrt0.3

    \[\leadsto \left(\left(x - \left(y - 1\right) \cdot z\right) - \color{blue}{\left(\sqrt[3]{\left(t - 1\right) \cdot a} \cdot \sqrt[3]{\left(t - 1\right) \cdot a}\right) \cdot \sqrt[3]{\left(t - 1\right) \cdot a}}\right) + \left(\left(y + t\right) - 2\right) \cdot b\]

  4. Final simplification0.3

    \[\leadsto \left(\left(x - \left(y - 1\right) \cdot z\right) - \left(\sqrt[3]{\left(t - 1\right) \cdot a} \cdot \sqrt[3]{\left(t - 1\right) \cdot a}\right) \cdot \sqrt[3]{\left(t - 1\right) \cdot a}\right) + \left(\left(y + t\right) - 2\right) \cdot b\]
