In her book, Africa Counts, Claudia Zaslavsky describes the Yoruba number system as a complex system based on 20 (vigesimal) that uses subtraction to express numbers. For example,
35 = (2 x 20) - 5; 47 = (3 x 20) - 10 - 3; 51 = (3 x 20) - 10 + 1;
According to the Yoruba system, the numbers from 1 to 10 have unique names. The numbers 11, 12, 13, and 14 are written additively (i.e., 11 = 10 + 1, 12 = 10 + 2, 13 = 10 + 3, 14 = 10 + 4). But the numbers from 15 through 19 are written using subtraction from 20. This same pattern continues for the 20s etc.

The Igbo political system was decentralized and based on a system of autonomous villages with democratic decision-making processes. Leadership was often based on merit, with elders and titled men making important decisions through consensus. The Yoruba political system was more centralized, with a system of monarchs ruling over city-states and regional councils of chiefs assisting in governance. The Oba (king) held significant power and authority, and leadership positions were often hereditary within ruling families.
