Whenever three or more numbers are multiplied, it will always be found that all except one, the multiplier, form a complexly expressed serialized multiplicand, i.e. a base (cf. #1360). For example, in Huastec (Mayan) 200, expressed as 2x5x20, 5×20, is a complex expression for 100 which is a base, as can be seen from 300 which is 3x5x20, etc. This indicates a grouping and hierarchization [(2x) (5×20)]. Note also #1358.
