1661 is a palindromic number.
You call it a palindromic sentence. If it isn't a sentence it is a palindromic phrase or palindromic sequence.
There are not just 13 non-palindromic numbers. Most numbers are non-palindromic.
"Palindromic" is the adjective form of "palindrome."
Example of a palindromic number is 16461.A palindromic number reads the same from both ends, which 16 fails to do.
The sum of two palindromic numbers is not necessarily a palindromic number. For example, adding the palindromic numbers 121 and 131 gives 252, which is also a palindrome. However, adding 121 and 122 results in 243, which is not a palindrome. Therefore, while some sums of palindromic numbers can be palindromic, it is not a guaranteed outcome.
'palindromic' means 'reads the same forward and backward', such as 'mom' and 'noon'. So yes, 878 a palindromic number.
89 does not have any other number - palindromic or otherwise.
As 20569.8 is not palindromic, any number that is like it must contain that property and similarly be non-palindromic, so no.
There are 90 palindromic numbers between 100 and 1000
No.
