Allan, 
  
Good suggestion. 

Also 
Simply put--- 
Where K and K1 are two parts of an integer and there difference is squared 
would = K1 appended to K  replacing the two parts  back to one.

"Numbers whose decimal form can be split into two parts, the square of 
whose difference is the original number." Is that too long? My concern is 
the ambiguity of the phrase, "split into two parts". 

Or ... "Numbers of the form K 10^n + L, L<10^n, that are equal to (K-L)^2."
