🆕 New Concept Discovered: Hexadecimal Number System
Representing values using base-16 notation.

Step 1: Understand the Hexadecimal System

The hexadecimal system is a base-16 numbering system. This means it requires 16 unique symbols to represent values.

Our standard decimal system (base-10) only has 10 numerical digits:

$$ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 $$

Step 2: Identify the symbols used for values 10 to 15

To represent the single-digit values from 10 to 15 without mixing them up with combinations of base-10 digits, the hexadecimal system uses the first six letters of the alphabet:

• \( \text{A} = 10 \)
• \( \text{B} = 11 \)
• \( \text{C} = 12 \)
• \( \text{D} = 13 \)
• \( \text{E} = 14 \)
• \( \text{F} = 15 \)

Therefore, hexadecimal numbers use both numerical digits (0–9) and letters (A–F).
