title: cmp jg how its work in assembly
body: <p>Hello everyone and thanks for trying to solve this exercise,I know that box al has the value ff, and in the box of bl has the value 03</p>
  
  <p>but when iam doing the cmp al,bl:
  its not like (al-bl) and 255-3 its 252 Which means it's bigger
  so why when iam run this code on emu8086 It does not make a jump to L1
  Instead he went into the order inc;</p>
  
  <p>(i think its maybe something with the msb i dont know)</p>
