The Three Languages

Imagine you need to count sheep. You could count in English (1, 2, 3... - this is denary/decimal, base 10). A computer counts in binary - only two words: "baa" or "silence" (0 or 1, base 2). But binary gets long fast: "101101010" for 362 sheep! So we use hexadecimal (base 16) as a shorthand - like abbreviations. It's not a different number, just a shorter way to write it. 16A in hex = 362 in denary = 101101010 in binary. Same sheep, three languages!
