Overall, there are two different counting systems in the Igbo language, a 20 based one (older version) and a 10 (decimal) based one (newer version). The lessons on this page mostly focus on the newer 10 based counting system, meaning the numbers are described based on the multiples of 10 instead of multiples 20. However, I did give examples of how to say both 20 and 400 using both systems.
