This system is built up of the digits 0-9 and letters A-F (which represent numbers 10-15). The main use of it is simplifying the binary notation - four bits are written as one letter.
Let us convert the number 2023 to the hexadecimal system. It can be done either by factorising based on 16 or converting the decimal 2023 to binary and using the table that shows what numbers and letters given bytes correspond to.

Technique 1:
2023 = 7x162 + 14x161 + 7x160 = 1792 + 224 + 7
Technique 2:
7 → 7
14 → E
7 → 7
So 2023(10) = 7E7(16)
