title: Assembly: how to add two 64 bit numbers by using 16 bit registers?
body: <p>I've searched for about one day but I can't find anything about adding 64 bit numbers in assembly - Nasm</p>
  
  <p>How can I do this ?</p>
  
  <p>My registers are only 16 bit and I have 2 numbers of 64 bits. The application I am using is Nasm. (it's for a school project)</p>
