It will be seen from the table that the only numbers having simple names are one, two, three, four, five, ten, fifteen, twenty, four hundred, and eight thousand; all the rest are compounds of these constructed on the principle that when the smaller number follows the larger the sum of the two is expressed, but when the smaller precedes the larger, their product is indicated. Molina and Leon y Gama are the chief authorities on the Nahua arithmetical system. All the writers agree perfectly respecting its details, but differ considerably in orthography. Molina writes each compound name together as a single word, while Gama often separates a word into its parts as I have done in every case, following his spelling.
