Final answer:
The question concerns a mathematics learning method where numerical answers are provided as ranges or hints to encourage understanding rather than memorization.
Step-by-step explanation:
The question refers to a method of learning or verifying answers in mathematics where numerical answers are given as ranges or hints. This technique is designed to help students stay on the right track without giving away the precise answer, thus discouraging shortcuts and encouraging a full understanding of the problem-solving process. In educational settings, answers may not be required to be memorized but rather understood conceptually so students can apply their knowledge to various problems. Often, in mathematics education, this approach is taken to ensure students are truly comprehending the material rather than just memorizing answers.
