One hundred is the Somali word for the number 100. It is a natural number that comes after 99 and before 101. In the base-ten (decimal) number system, one hundred is ten multiplied by ten, that is 10 × 10, or 10 raised to the second power.
One hundred is written in Arabic-Hindu numerals as 100, while the Roman numeral system denotes it as C. Because the global number system is based on ten, one hundred became an important threshold for measuring quantity, proportion, and measurement.
Linguistic usage
In Somali, multiples of one hundred are formed by preceding a number before the word: two hundred (200), three hundred (300), up to nine hundred (900). One thousand is the next higher number and equals ten hundred. When combined, they are expressed as one hundred and five (105) or two hundred and twenty (220).
The word 'one hundredth of' expresses a part of one hundred, corresponding to the English word 'percent'; for example, 'five one hundredths of' means 5%. Similarly, 'one hundred years' refers to a century.
Mathematical properties
One hundred is a perfect square, since it equals 10². Its divisors are 1, 2, 4, 5, 10, 20, 25, 50, and 100. The sum of its proper divisors—those less than the number itself—exceeds 100, making it an abundant number. It is also the sum of the first ten odd numbers: 1 + 3 + 5 + ... up to 19.
Other applications
One hundred is the base of the percentage system used to measure exam results, bank interest rates, and statistics. Various measurements derive from it, such as the centimeter, which equals one hundredth of a meter, or the century, which means one hundred years. In the monetary systems of many countries, the smallest unit typically consists of one hundred subdivisions of the main currency.
