Line 14: :::: FWIW my experience as a reader is that using the word 'sum' at that point certainly proved confusing at first reading, and even now feels distractingly odd. 211 is certainly a '''number''' – a member of the set of integers – but the point you are making about it seems to be precisely that it is '''not''' a sum (the result of an addition) within this system.
