2. Hexadecimal Symbols
The symbols used in hexadecimal are 0-9 and A-F. These correspond to the following numbers in denary:
Denary  | 
      0  | 
      1  | 
      2  | 
      3  | 
      4  | 
      5  | 
      6  | 
      7  | 
      8  | 
      9  | 
      10  | 
      11  | 
      12  | 
      13  | 
      14  | 
      15  | 
    
Hexadecimal  | 
      0  | 
      1  | 
      2  | 
      3  | 
      4  | 
      5  | 
      6  | 
      7  | 
      8  | 
      9  | 
      A  | 
      B  | 
      C  | 
      D  | 
      E  | 
      F  | 
    
When you go beyond 15, you run out of symbols. So, just like in denary and binary, you have to start again in the next number position.
Denary  | 
      16  | 
      17  | 
      18  | 
      19  | 
      20  | 
      21  | 
      22  | 
      23  | 
      24  | 
      25  | 
      26  | 
      27  | 
      28  | 
      29  | 
      30  | 
      31  | 
    
Hexadecimal  | 
      10  | 
      11  | 
      12  | 
      13  | 
      14  | 
      15  | 
      16  | 
      17  | 
      18  | 
      19  | 
      1A  | 
      1B  | 
      1C  | 
      1D  | 
      1E  | 
      1F  | 
    
Once we have gone past the first 16 numbers, a 1 is added in front of the next 16 numbers (similar to denary when we go from 0-9 and then move on to 10-19)
