16 (sixteen) is the natural number following 15 (number), 15 and preceding 17 (number), 17. It is the 4, fourth power of two. In English speech, the numbers 16 and 60 (number), 60 are sometimes confused, as they sound similar. Mathematics 16 is the ninth composite number, and a square number: 4 (number), 42 = 4 × 4 (the first non-unitary fourth-power prime number, prime of the form ''p''4). It is the smallest number with exactly five divisors, its proper divisors being , , and . Sixteen is the only integer that Equation x^y = y^x, equals ''m''''n'' and ''n''''m'', for some unequal integers ''m'' and ''n'' (m=4, n=2, or vice versa). It has this property because 2^=2\times 2. It is also equal to 32 (see tetration). The aliquot sum of 16 is 15 (number), 15, within an aliquot sequence of four composite members (16, 15 (number), 15, 9 (number), 9, 4 (number), 4, 3 (number), 3, 1 (number), 1, 0) that belong to the prime 3-aliquot tree. *Sixteen is the largest known integer , for ...

Hexadecimal
Hexadecimal (also known as base-16 or simply hex) is a Numeral system#Positional systems in detail, positional numeral system that represents numbers using a radix (base) of sixteen. Unlike the decimal system representing numbers using ten symbols, hexadecimal uses sixteen distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9 and "A"–"F" to represent values from ten to fifteen. Software developers and system designers widely use hexadecimal numbers because they provide a convenient representation of binary code, binary-coded values. Each hexadecimal digit represents four bits (binary digits), also known as a nibble (or nybble). For example, an 8-bit byte is two hexadecimal digits and its value can be written as to in hexadecimal. In mathematics, a subscript is typically used to specify the base. For example, the decimal value would be expressed in hexadecimal as . In programming, several notations denote hexadecimal numbers, usually involving a prefi ...
