🇬🇧 Hexadecimal meaning: English Vocabulary Flash Card

Hexadecimal is a special way of writing numbers where each place can go from 0 up to 15 before it needs to ‘carry’ to the next place. Instead of just using the digits 0–9 like in normal (decimal) numbers, the hexadecimal system also uses the letters A, B, C, D, E, and F to mean the values 10, 11, 12, 13, 14, and 15. Hexadecimal numbers are often used in computers because it’s an easier way to write very long binary (0s and 1s) numbers in a shorter, more readable form.
