Frequently Asked Questions
What makes a number "magic"?
In recreational mathematics, "magic" or "neat" numbers have unique properties. This can mean they read the same forwards and backwards (Palindromes), consist of a single repeating digit (Repdigits), or equal the sum of their own digits raised to the power of the number of digits (Armstrong numbers).
What is a Palindromic Number?
A palindromic number remains the same when its digits are reversed. For example, 16461 is a palindrome. They are often studied in number theory and recreational math.
What is an Armstrong (Narcissistic) Number?
An Armstrong number is an n-digit number that is equal to the sum of the nth powers of its digits. For example, 153 is a 3-digit number, and 1^3 + 5^3 + 3^3 = 1 + 125 + 27 = 153.
What is a Repdigit?
A repdigit (short for repeated digit) is a number composed of just one digit repeated multiple times, such as 777 or 99999. They are trivial in base 10 but have interesting properties in modular arithmetic.
