Counting in hexadecimal is basically like counting in decimal - just remember that the highest digit is "F" instead of "9". So, after "9", you continue with the digits "A", "B", ... "F", and after the last digit gets to "F", you set it back to zero (just as in decimal, you would set the last digit to zero after a "9"), and add one to the previous digit. For example, the next number after 3F is 40. And the next number after 3FF is 400.
