@ -497,9 +497,10 @@ time we are concerned with judgements asserting associativity.
Now, we apply the rules to all the judgements we know about. The base
case tells us that `(zero + n) + p ≡ zero + (n + p)` for every natural
`n` and `p`. The inductive case tells us that if `(m + n) + p ≡ m +
(n + p)` (on the day before today) then `(suc m + n) + p ≡ suc m + (n
+ p)` (today). We didn't know any judgments about associativity
before today, so that rule doesn't give us any new judgments.
