[edit] In mathematics

One hundred is the square of 10 (in scientific notation it is written as 10²). The standard SI prefix for a hundred is "hecto-".

One hundred is the basis of percentages (literally "per hundred"), with 100% being a full amount.

It is the sum of the first nine prime numbers, as well as the sum of four pairs of prime numbers (47 + 53, 17 + 83, 3 + 97, 41 + 59), and the sum of the cubes of the first four integers (100 = 1³ + 2³ + 3³ + 4³). Also, 2⁶ + 6² = 100, thus 100 is a Leyland number.

One hundred is also an 18-gonal number. It is divisible by the number of primes below it, 25 in this case. But it can not be expressed as the difference between any integer and the total of coprimes below it, making it a noncototient. However, it can be expressed as a sum of some of its divisors, making it a semiperfect number.

100 is a Harshad number in base 10, and also in base 4, and in that base it is a self-descriptive number.
