This course exists of one vid, which is about 46 minutes long and is a part of his learning to program course.
This is a great introduction into several number systems, binary, octo and hexa. It explains what relationship is between these number bases, how to converse to another base number and it covers how to represent different kind of numbers as bits. This vid does make it painfully clear how important math is!
The vid might be 2 years old, but I don’t think the materials covered will outdate soon
Eventhough I found the subject intresting and Brian Will is a great tutor, I did had to watch the vid in three parts. Brian Will his boring and his voice made me almost fall asleep
Supplementary notes and the slides used in the vid, can be found here.
