Staff Review
This video will teach you how to add basic numbers in other bases. It begins with base 10 and moves on to some other bases such as base 8, base 4, and base 2. Because this is an introductory video, there is no carry-over in any problems except in the final problem. This is a great place to start in order to understand operations in bases other than base 10.
