title: 0x00000000 hexadecimal?
body: <p>I had always been taught  0–9 to represent values zero to nine, and A, B, C, D, E, F for 10-15.</p>
  
  <p>I see this format 0x00000000 and it doesn't fit into the pattern of hexadecimal. Is there a guide or a tutor somewhere that can explain it?</p>
  
  <p>I googled for hexadecimal but I can't find any explanation of it.</p>
  
  <p>So my 2nd question is, is there a name for the 0x00000000 format?</p>
