\(\begin{cases} a + \frac{y}{z} \cdot \left(x - a\right) & \text{when } z \le -9.444944393823517 \cdot 10^{+271} \\ \left(x + \frac{y - z}{\left(t + 1.0\right) - z} \cdot a\right) + \frac{y - z}{\left(t + 1.0\right) - z} \cdot \left(-x\right) & \text{when } z \le 9.019727682954405 \cdot 10^{+206} \\ a + \frac{y}{z} \cdot \left(x - a\right) & \text{otherwise} \end{cases}\)

    if z < -9.444944393823517e+271 or 9.019727682954405e+206 < z

    1. Started with
      \[x + \frac{y - z}{\left(t + 1.0\right) - z} \cdot \left(a - x\right)\]
      29.6
    2. Applied taylor to get
      \[x + \frac{y - z}{\left(t + 1.0\right) - z} \cdot \left(a - x\right) \leadsto \left(\frac{y \cdot x}{z} + a\right) - \frac{y \cdot a}{z}\]
      12.2
    3. Taylor expanded around inf to get
      \[\color{red}{\left(\frac{y \cdot x}{z} + a\right) - \frac{y \cdot a}{z}} \leadsto \color{blue}{\left(\frac{y \cdot x}{z} + a\right) - \frac{y \cdot a}{z}}\]
      12.2
    4. Applied simplify to get
      \[\color{red}{\left(\frac{y \cdot x}{z} + a\right) - \frac{y \cdot a}{z}} \leadsto \color{blue}{a + \frac{y}{z} \cdot \left(x - a\right)}\]
      1.4

    3. Applied sub-neg to get
      \[x + \frac{y - z}{\left(t + 1.0\right) - z} \cdot \color{red}{\left(a - x\right)} \leadsto x + \frac{y - z}{\left(t + 1.0\right) - z} \cdot \color{blue}{\left(a + \left(-x\right)\right)}\]
      7.2
    4. Applied distribute-lft-in to get
      \[x + \color{red}{\frac{y - z}{\left(t + 1.0\right) - z} \cdot \left(a + \left(-x\right)\right)} \leadsto x + \color{blue}{\left(\frac{y - z}{\left(t + 1.0\right) - z} \cdot a + \frac{y - z}{\left(t + 1.0\right) - z} \cdot \left(-x\right)\right)}\]
      7.2
    5. Applied associate-+r+ to get
