Derivation

1. Initial program 49.2

   \[1.7 \cdot 10^{+308} \cdot t - 1.7 \cdot 10^{+308}\]

2. Initial simplification49.2

   \[\leadsto 1.7 \cdot 10^{+308} \cdot t - 1.7 \cdot 10^{+308}\]
3. Using strategy rm

4. Applied fma-neg0

   \[\leadsto \color{blue}{(\left( 1.7 \cdot 10^{+308} \right) \cdot t + \left(-1.7 \cdot 10^{+308}\right))_*}\]

5. Final simplification0

   \[\leadsto (\left( 1.7 \cdot 10^{+308} \right) \cdot t + \left(-1.7 \cdot 10^{+308}\right))_*\]
