Master Spanish Numbers

Spanish numbers 0–15 each have unique names that must be memorized, but from 16 onward the system becomes predictable: dieciséis ("ten-and-six"), diecisiete, and so on. Numbers 21–29 are contracted into single words (veintiuno, veintidós), while 31+ use separate words joined by y ("and"). Most Spanish-speaking countries use the long scale, where un billón means one million millions — a trillion in American English.
