    if z < -3.643176247714988e+162 or 5.903305365345926e+148 < z

    1. Started with
      \[x + \frac{y - z}{\left(t + 1.0\right) - z} \cdot \left(a - x\right)\]
      30.9
    2. Applied taylor to get
      \[x + \frac{y - z}{\left(t + 1.0\right) - z} \cdot \left(a - x\right) \leadsto \left(\frac{y \cdot x}{z} + a\right) - \frac{y \cdot a}{z}\]
      11.3
    3. Taylor expanded around inf to get
      \[\color{red}{\left(\frac{y \cdot x}{z} + a\right) - \frac{y \cdot a}{z}} \leadsto \color{blue}{\left(\frac{y \cdot x}{z} + a\right) - \frac{y \cdot a}{z}}\]
      11.3
    4. Applied simplify to get
      \[\color{red}{\left(\frac{y \cdot x}{z} + a\right) - \frac{y \cdot a}{z}} \leadsto \color{blue}{a + \frac{y}{z} \cdot \left(x - a\right)}\]

    2. Using strategy rm
      4.6
    3. Applied div-inv to get
      \[x + \color{red}{\frac{y - z}{\left(t + 1.0\right) - z}} \cdot \left(a - x\right) \leadsto x + \color{blue}{\left(\left(y - z\right) \cdot \frac{1}{\left(t + 1.0\right) - z}\right)} \cdot \left(a - x\right)\]
      4.7
    4. Applied associate-*l* to get
      \[x + \color{red}{\left(\left(y - z\right) \cdot \frac{1}{\left(t + 1.0\right) - z}\right) \cdot \left(a - x\right)} \leadsto x + \color{blue}{\left(y - z\right) \cdot \left(\frac{1}{\left(t + 1.0\right) - z} \cdot \left(a - x\right)\right)}\]
      5.0
    5. Applied simplify to get
