101 (one hundred [and] one) is the natural number following 100 and preceding 102. When written without the "and," 101 is the smallest non-negative integer requiring thirteen letters in English. In the US, especially in academia, the number written or spoken with "and" is deprecated just like in "four and twenty" or "four score and seven"; "and" should only be used in a mixed number when traversing the decimal point or otherwise starting the fractional part after stating the integral part. The popularity of The 101 Dalmatians by British author, Dodie Smith, creates difficulty for US teachers in this regard.

101 is the 26th prime number and a palindromic number (therefore also a palindromic prime). The next prime is 103, with which it comprises a twin prime (making 101 a Chen prime). Because the period length of its reciprocal is unique among primes, 101 is a unique prime. 101 is an Eisenstein prime with no imaginary part and real part of the form 3n − 1.

For a 3-digit number in base 10, this number has a relatively simple divisibility test. The number is split into groups of four, starting with the rightmost four, and added up to produce a 4-digit number. If this 4-digit number is of the form 1000a + 100b + 10a + b (where a and b are integers from 0 to 9), such as 3232 or 9797, or of the form 100b + b, such as 707 and 808, then the number is divisible by 101. This might not be as simple as the divisibility tests for numbers like 3 and 5, and it might not be terribly practical, but it is simpler than the divisibility tests for other 3-digit numbers. In mathematics, a divisor of an integer n, also called a factor of n, is an integer which evenly divides n without leaving a remainder. ...
