A more thorough explanation:

Definition: Heuristic refers to a problem-solving method that involves using trial-and-error and other experimental techniques to learn and discover.

Example: A student trying to solve a math problem by testing different formulas until they find the one that works is using a heuristic approach.

Explanation: The example illustrates heuristic because the student is using trial-and-error to find the solution to the problem. They are experimenting with different formulas until they find the one that works. This approach is often used in situations where there is no clear solution or when the problem is complex and requires exploration and experimentation.
