Binary Math for Electronic Engineering / Computer Science

I am taking an electrical engineering course and I am having a hard time understanding some of the binary math.

I would like to suggest having a series of videos devoted to binary math. There are two videos that I found that discuss binary addition and I think the other is binary multiplication however as these relate to Electrical Engineering and Computer Science they are not enough. I think there should be a video about subtraction and division as well. I think there should also be videos about signed binary numbers - these are numbers where the most significant bit is used to determine positive or negative magnitude. If there are videos about signed numbers that means there would also need to be videos about finding the one's and two's complements of binary numbers.
