HI guys.
I have a problem with my assignment like:
Hexadecimal numbers are made using the sixteen digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F. For a four digit number, the most significant digit is restricted to the digits 7 to C and the least significant digit is restricted to the digits 9 to F.How many numbers are there?
Because i am an overseas student, so it is very difficult for me to understand "the most significant digit is restricted to the digits 7 to C and the least significant digit is restricted to the digits 9 to F", can you explain to me,please? Or can you give some examples with this pattern, please?
Thank you very much.
