Derivation

  1. Initial program 0.1

    \[x \cdot \left(\left(\left(\left(y + z\right) + z\right) + y\right) + t\right) + y \cdot 5\]
  2. Using strategy rm

  3. Applied associate-+l+0.1

    \[\leadsto x \cdot \left(\color{blue}{\left(\left(y + z\right) + \left(z + y\right)\right)} + t\right) + y \cdot 5\]

  4. Applied associate-+l+0.1

    \[\leadsto x \cdot \color{blue}{\left(\left(y + z\right) + \left(\left(z + y\right) + t\right)\right)} + y \cdot 5\]

  5. Applied distribute-lft-in0.1

    \[\leadsto \color{blue}{\left(x \cdot \left(y + z\right) + x \cdot \left(\left(z + y\right) + t\right)\right)} + y \cdot 5\]

  6. Final simplification0.1

    \[\leadsto \left(x \cdot \left(y + z\right) + x \cdot \left(\left(z + y\right) + t\right)\right) + y \cdot 5\]
