"Software developers and system designers widely use hexadecimal numbers because they provide a human-friendly representation of binary-coded values."
A system that uses sixteen digits (0-9 and A-F) to represent all numbers.
Binary system: Understanding the basic system of counting in base 2, which is the building block for all higher number systems.
Decimal system: The most commonly used number system, which uses ten digits (0-9) in base 10.
Hexadecimal system: A base-16 number system that is widely used in computer programming and digital technology.
Converting between number systems: Learning how to convert numbers between different number systems, such as binary, decimal, and hexadecimal.
Counting: Learning how to count in hexadecimal and understand the relationship between the different digits.
Binary-to-hexadecimal conversion: Understanding how to convert binary numbers to hexadecimal.
Decimal-to-hexadecimal conversion: Understanding how to convert decimal numbers to hexadecimal.
Hexadecimal notation: Learning how to write numbers in hexadecimal notation.
Hexadecimal arithmetic: Understanding how to perform addition, subtraction, multiplication, and division in hexadecimal.
Character encoding: Understanding how hexadecimal is used in character encoding, such as ASCII and Unicode.
Color encoding: Understanding how hexadecimal is used to encode colors in digital graphics.
Data representation: Understanding how hexadecimal is used to represent data in computer programming, such as memory addresses and machine code instructions.
Hexadecimal notation in assembly language: Understanding how hexadecimal is used in assembly language coding.
Checksums: Understanding how hexadecimal is used in error detection, such as checksums.
Cryptography: Understanding how hexadecimal is used in cryptography, such as encoding/hashing algorithms (e.g., MD5 or SHA-2).
"hexadecimal uses sixteen distinct symbols, most often the symbols '0'–'9' to represent values 0 to 9, and 'A'–'F' (or alternatively 'a'–'f') to represent values from ten to fifteen."
"Each hexadecimal digit represents four bits (binary digits), also known as a nibble (or nybble)."
"An 8-bit byte can have values ranging from 00000000 to 11111111 (0 to 255 decimal) in binary form, which can be conveniently represented as 00 to FF in hexadecimal."
"The decimal value 30,227 would be expressed in hexadecimal as 761316."
"The prefix 0x is used in C, which would denote this value as 0x7613."
"In mathematics, a subscript is typically used to specify the base."
"Hexadecimal is used in the transfer encoding Base16, in which each byte of the plaintext is broken into two 4-bit values and represented by two hexadecimal digits."
"Unlike the decimal system representing numbers using ten symbols, hexadecimal uses sixteen distinct symbols."

"[...] hexadecimal (also base-16 or simply hex) numeral system is a positional numeral system that represents numbers using a radix (base) of sixteen."
