Numbers which read the same both forward and backward,
such as 36563, are called palindromic numbers.
Can we make a palindromic number,
staring with any number
Take any number. Reverse its
digits and add to the original.
Reverse the digits of this number
and add. Continue till we get a
palindromic number.
Two digit number = 56
Reverse the digits = 65
Add these numbers = 56 +
65
121
Three digit number = 326
Reverse the digits = 623
Add these numbers = 326+
623
