For example, enter 9 and you will find out that 9 is the only number (except one) which is equal to the sum of the digits of its square and that 9 is the smallest odd composite number. Below the list of information are common properties of the number entered. Some numbers also include links to web pages about that number - for example, enter the number 6 and there is a link to Some Thoughts on Number 6 by John Baez.
