For level 6 of Addition World, I came up with
rw add_assoc,
rw add_assoc,
rw add_comm c b,
refl,
and it works, but in the solutions, it had
rw add_assoc,
rw add_comm b c,
rw ←add_assoc,
refl,
is there anything different or better about the latter rather than the first?
Joseph O (Apr 21 2022 at 22:55):
It seems to be the same as mine, but just switching around the order. Is the latter solution more readable though?
Eric Rodriguez (Apr 21 2022 at 23:00):
no, they're both reasonable!
Joseph O (Apr 21 2022 at 23:05):
Which would you prefer?
Arthur Paulino (Apr 21 2022 at 23:09):
You should be able to say rw [add_assoc, add_assoc, add_comm c b], refl,

(just to explore the syntax)

they didn't show us that in the nat number game yet
