Question

How do you represent the (decimal) integer 50 in, oh, "hexadecimal," otherwise known as base-16?

Answer 1

This is similar to how you solve base 2. Instead of dividing by 2, you simply need to divide by 16 here.

50/16 Q=3 R=2
3/16 Q=0 R=3

So 50 in base 16 is 32 (commonly written as 0x32).

You need to remember that numbers above 9 are denoted as alphabets here. So a 10 is an A, 11 is B, and 15 is F.
