Press "1" to find the palindrome of a number. Press "2" to see the numbers you've entered and their palindromic sums. Very large numbers won't work because Scratch can't handle those, and they get converted which messes it up.
A palindrome is a word or number that is the same forwards and backwards, like racecar. A palindromic sum is a number added to it self backwards to make it the same forwards and backwards. Some numbers, like 76 have to be added multiple times. 76 added to 67 is 143, added to 341 is 484. That also means the palindrome of 76 is equal to the palindrome of 143, 341, and 67.
