How 15 is built in Yorùbá
- ẹ́ẹ̀dógún is àrún (5) taken away from ogún (20): 20 − 5 = 15. The "dín" in the word means "less".
- ogún (20) is the basic unit of the traditional system: one score.
- Yorùbá counts down from the next ten for any number ending in 5 to 9, so 15 is reached from 20, not from 10.
Modern base-10 form
mẹ́wàá ó lé márùn-ún
In school maths, prices and phone numbers, the modern system only adds: "ó lé" means "and more", so the parts are simply summed.
