thanks a lot this is literally a life saver for me. i was unable to solve a 6 mark question before this but now i feel confident knowing the basic rules needed to apply to these types of questions. very concise, easy-to-understand video and short and simple. 10/10
Good explanation! Although I asked myself about the result 8 - 14 = -6 here your result is (1)1110 . unsigned numbers are always positive from 0 to 255 for 4-Bit. That means I can not calculate a negative number with unsigned numbers. Correct?
