Hexadecimal is a base-16 numbering system that uses 16 symbols: numbers 0-9 and letters A-F (representing values 10-15) to express binary information compactly in programming systems.
To convert hex to decimal, multiply each digit by 16 raised to the power of its position index (starting from 0 on the right), and then sum all results. For example: 1A = (1 * 16¹) + (10 * 16⁰) = 16 + 10 = 26.
