On our first Monday lecture with Karcher, we learned about different number systems from many places in history. We learned about the Binary Number System. This system only uses 0 and 1’s. Additionally, we learned about the Hexadecimal number system and how it is the foundation of the naming of digital colors. To practice our skills, we played a numeric game that focused on converting binary numbers to hexadecimal. The game was super fun and Ginny was the champion!
