\((y * x + \left((i * c + \left(a \cdot b\right))_*\right))_* + t \cdot z\)
  1. Started with
    \[\left(\left(x \cdot y + z \cdot t\right) + a \cdot b\right) + c \cdot i\]
    0.0
  2. Applied simplify to get
    \[\color{red}{\left(\left(x \cdot y + z \cdot t\right) + a \cdot b\right) + c \cdot i} \leadsto \color{blue}{(i * c + \left(a \cdot b\right))_* + (y * x + \left(t \cdot z\right))_*}\]
    0.0
  3. Using strategy rm
    0.0
  4. Applied fma-udef to get
    \[(i * c + \left(a \cdot b\right))_* + \color{red}{(y * x + \left(t \cdot z\right))_*} \leadsto (i * c + \left(a \cdot b\right))_* + \color{blue}{\left(y \cdot x + t \cdot z\right)}\]
    0.0
  5. Applied associate-+r+ to get
    \[\color{red}{(i * c + \left(a \cdot b\right))_* + \left(y \cdot x + t \cdot z\right)} \leadsto \color{blue}{\left((i * c + \left(a \cdot b\right))_* + y \cdot x\right) + t \cdot z}\]
    0.0
  6. Applied simplify to get
    \[\color{red}{\left((i * c + \left(a \cdot b\right))_* + y \cdot x\right)} + t \cdot z \leadsto \color{blue}{(y * x + \left((i * c + \left(a \cdot b\right))_*\right))_*} + t \cdot z\]
