Episode 1 - Why the class? | Why in Yoruba? | Number base system


https://www.youtube.com/watch?v=RRW-Un4RAp0

Welcome to our new class! In the first part of today's topic, we discussed the various motivations behind teaching this class in Yoruba, our mother tongue. In the second part, we learned about the concept of number base systems and how to write and convert numbers between base 10 and other bases. We covered the process of converting numbers from base 10 to other bases, as well as the reverse process of converting numbers from other bases back to base 10.
