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

16 to the power of 2 is 256! - There are so many errors in this video if I was you I'd scrap it and start again!

Around 7:45 when your doing the second hex to deanery isn't it 156 cause 16 x 9 = 144 + 12 = 156

In my opinion there is a better way to do Denary to hex, what i do is first turn the denary to binary and then turn the binary into hex. Just wanted to say if someone found his way more difficult.

You've put the title of the column on the right as Hex --> Binary but you've converted Hex into Denary?
