Comments

From Benjamin M. Covert, Oct 30 2018: (Start)

Numbers on the interval of n [200,299] use the "er" (二) form rather than the "liang" (两) form.

Numbers for n = 100m + c where m is a whole number and c is on the interval [1,9] have a "ling" (零) after the "bai" (百) adding 13 additional strokes. (End)

Examples

			The Chinese number 15 (十五) takes 6 strokes to write so a(15) = 6
