17.13

千姟 (fanqie: 改 + 孩; the Suanjing says: "A hundred thousand is called an yì (億); ten yì are called a zhào (兆); ten zhào are called a jīng (京); ten jīng are called a gāi (姟)." It is a name for a numerical order. The Gujin zhengzi says: "It means great; a number. It is classified under woman (女) and takes 亥 as phonetic." In the sūtra it is written with earth (土 as phonetic/radical), which is an erroneous usage).
