Why do you assume that OP has a computer science degree?
IT has always been a sector where you can have a degreeless career. Moreover, plenty of IT degrees are not computer science (data science degrees, to take a popular example)
I did a bachelors degree in Electronics and Communication engineering. It was standard to watch things go from a diode, to transistor, to a flip flop, to a register, then 8/16/32 bit adders- Once here subtraction is just addition in 2's compliment. Multiplication is repeated addition, and division being repeated subtraction.
After this you immediately go and learn 8085, and then 8086
Pretty sure they are not anymore, when I was majoring in cs the deepest I was taught was assembly and architecture at a high level. I then switched to computer engineering and that’s where digital logic was a mandatory class.
