palindr89.zip1k14-11-27File is not ratedPalindromic Numbers
A palindrome or palindromic number is a number that has the same value when read from both directions (left to right and right to left). This program investigates the generation of palindromic numbers using the Lychrel process. Full instructions are provided in the README file.

Experiment with Kaprekar's constant, the famous 6174! This program accepts 4 digit numbers and performs the Kaprekar's routine until it reaches 6174, showing all the intermediate steps. For more info on Kaprekar's constant, look at the wikipedia article (http://en.wikipedia.org/wiki/6174_%28number%29). To execute, just type kaprekar()

Have ya ever wanted to find out what day of the week (Monday, Tuesday, etc) you were born, or when a particular date took place(July 4, 1776)? Well, with this neat little program, all you have to do is enter in the month(12), day(19), and year(1987), and voila, the day of the week appears! I used a formula that I found on the internet somewhere. It is really small, so download it today! This is the ported version of the Day of the Week Finder for the TI-83 Plus/Silver Edition by me.
