Knowing more about mathematical stories and related knowledge will help to increase children's enthusiasm and initiative in learning and cultivate their interest invisibly. The following is a guess of the number of math stories I share with you. Let's read it together!

If there is a number that reads the same from left to right, it is called palindrome number. For example, 202,737,5005,6666 are palindromes.

There is a famous "palindrome conjecture" in mathematics, which has not been completely proved so far. For example, randomly find a decimal number, turn it upside down, add these two numbers, then add this sum to the original sum in turn, and then repeat this process repeatedly until you get a palindrome.

For example, 83 is 38, 83+38= 12 1, and a palindrome number 12 1 can be obtained by one-step operation.

For another example, 68+86= 154,154+451= 605,605+506 =11,and so on.

And "palindrome guessing" means that no matter what number you use at the beginning, you can get a palindrome number after a limited number of steps.

Can all numbers generate palindromes after such operations? I'm not sure yet. For example, the number 196 may prove that this "palindrome conjecture" is not established. Because mathematicians have calculated hundreds of thousands of steps with electronic computers, but they have not yet got a palindrome number. However, it cannot be said that this number will never become a palindrome.
