    Design a function for an automated grading system that determines if a student's numerical answer can be expressed as the difference between two perfect square numbers, which is crucial for assessing their understanding of algebraic relationships. The function should help teachers quickly verify if students have correctly identified numbers that can be represented in the form a² - b², where a and b are positive integers.
