okay so here is what it's asking . it is not a palindrome because it doesn't spell it the same way for example radar spelled backwards is radar but race spelled backwards isn't race it's ecar which isn't a word. so it is not a palindrome. the absolute value of a number just means if it's a negative make it a positive and if its a positive it stays a positive
here's the number line:
___-5__-4__-3__-2__-1__0__1__2__3__4___5_______
r a c e c a r
e
