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
