Hexadecimal
Definition
Hexadecimal is a number system that uses base-16 instead of base-10. It uses digits from 0 to 9 and letters from A to F to represent values from 0 to 15.
Analogy
Think of hexadecimal as using emojis instead of regular numbers. Instead of counting from 0 to 9 and then starting over, you count from 😄 to 😂 and then continue with the letters A, B, C, D, E, and F before reaching 🔥 which represents the value 15.
