Question

While going through maths topics i reached palindrome numbers.There i learnt that if you add a number to its reverse you get a palindrome number.But one such number,176+671=847 which is not a palindrome number.I tried again and still didnt get a palindrome number.Please explain.

Answer 1

probably the theory will hold only if the sum of the middle digits of the number will be less than 10
In 176, sum of 7 with 7 is 14 which is more than 9 so you'll not get a palindrome here.
