Hexadecimal to two places

Learning basic hex is easy, if you don't know how to do it, click here. If you have learned hex 1-15 then lets add another layer of complexity, for example  the single digit "A" in hex is 10 in denary which is 1010 in binary . However what about two digit hex "2F" in hex equal?

How to convert 2 digit hex to denary (and binary)

The hex number 2F equals 47 in denary, but how?
