This calculator determines if an integer you entered has any of the following properties:
* Even or Odd
* Evil or Odious
* Perfect, Abundant, or Deficient
* Triangular
* Prime or Composite
* Automorphic (Curious)
* Undulating
* Square
* Cube
* Palindrome
* Repunit
* Apocalyptic Power
* Pentagonal
* Tetrahedral (Pyramidal)
* Narcissistic (Plus Perfect)
* Catalan

This is also built with our shortcut commands. Simply enter a positive integer and click the number property option OR type something like "Tell me about 125" into the search engine.

I'll add more properties as time goes on. Let me know if you have questions or enhancements.

Enjoy your summer!
