Understanding Hexadecimal Numbers

Hexadecimal (hex) is a base-16 number system commonly used in computing and digital systems. Unlike the decimal system (base-10), hex uses sixteen distinct symbols: the numbers 0-9 and the letters A-F to represent values from 0 to 15.

Why Use Hexadecimal?

Compact representation of binary data
Commonly used in programming and computer science
Easier to read and write than binary
Used in color codes, memory addresses, and digital systems

Hex to Decimal Conversion

Each position in a hex number represents a power of 16. For example:

3A₁₆ = (3 × 16¹) + (10 × 16⁰) = (3 × 16) + 10 = 58₁₀
