Avoid abbreviating "numerator" as "numer", to allow catching typo "numer" elsewhere

`typos.toml` has an exception for "numer", to avoid flagging its use as
an abbreviation for "numerator". Remove the use of that abbrevation,
spelling out "numerator" instead, and remove the exception, so that typo
checks can find future instances of "numer" as a typo for "number".
