OCR GCSE Computing: Hexadecimal (Number) - Topic 9 [OLD COURSE]

A direct continuation from the previous video which focused mainly on binary, in this video I explain hex and several important calculations. EDIT: Two mistakes in the video, at around 7:50 the answer is 156, not 166 and at the end the calculation is for 0011 1010 not 0011 1011 as stated in the question. Apologies Email: [email protected]
