Wrong explanation of Hexadecimal system #54

Closed stefanbrummel closed 8 years ago

stefanbrummel commented 8 years ago

In hexadecimal, we have 16 symbols to form numbers. Because 0-9 are not enough symbols, we also use A-F. And it starts at zero. So:

  • the number 4 in hexadecimal is 3
  • the number 12 in hexadecimal is B

This is not correct: The (decimal) number 4 in hexadezimal is also 4, due to dezimal and hexadezimal starting at zero. The same mistake has happened in the second line: The (decimal) number 12 in hexadecimal is C.

This chart makes it pretty easy to see the relation between the 3 counting systems. Maybe something like it could be used.
