\(\left(e + \left(d + a\right)\right) + \left(c + b\right)\)
  1. Started with
    \[\left(\left(\left(e + d\right) + c\right) + b\right) + a\]
    0.4
  2. Using strategy rm
    0.4
  3. Applied pow1 to get
    \[\left(\left(\color{red}{\left(e + d\right)} + c\right) + b\right) + a \leadsto \left(\left(\color{blue}{{\left(e + d\right)}^{1}} + c\right) + b\right) + a\]
    0.3
  4. Applied taylor to get
    \[\left(\left({\left(e + d\right)}^{1} + c\right) + b\right) + a \leadsto \left(\left({\left(d + e\right)}^{1} + c\right) + b\right) + a\]
    0.3
  5. Taylor expanded around 0 to get
    \[\left(\left({\color{red}{\left(d + e\right)}}^{1} + c\right) + b\right) + a \leadsto \left(\left({\color{blue}{\left(d + e\right)}}^{1} + c\right) + b\right) + a\]
    0.3
  6. Applied simplify to get
    \[\color{red}{\left(\left({\left(d + e\right)}^{1} + c\right) + b\right) + a} \leadsto \color{blue}{\left(e + \left(d + a\right)\right) + \left(c + b\right)}\]
    0.3
