Is this question worth of 4th level?
Nice solution!Entered − 8 in first try then saw that − 9 2 and got right in second try!
The largest square under hundred is 8 1 , which is 9 2 . Thus
x m a x = 9
But x can even be a negative integer as the square of a negative integer is a positive. Thus
x m i n = − 9
Hence x m i n − x m a x = − 9 − 9 = − 1 8

As x is a integer the maximum value of x is 9.
Now, this is the tricky part. ( x ) 2 = ( − x ) 2 which means that -9 will be least value of x
Therefore answer =-9-9 = -18
