Derivation

  1. Initial program 0.1

    \[\left(\left(\left(\left(x + y\right) + y\right) + x\right) + z\right) + x\]

  2. Simplified0.1

    \[\leadsto \color{blue}{x + \left(\left(x + y\right) \cdot 2 + z\right)}\]

  3. Final simplification0.1

    \[\leadsto x + \left(\left(x + y\right) \cdot 2 + z\right)\]
