Answer :

Final answer:

To prevent the "main sub" problem with Solver, break complex problems into manageable subproblems, use resources like LibreTexts for solution ideas, and systematically explore potential solutions with tools like a concept combination table.

Explanation:

To prevent the "main sub" problem from occurring with Solver, it is essential to approach complex problems by breaking them down into smaller, more manageable subproblems. This allows for a focused approach to each individual aspect of the problem before attempting to solve the larger issue.

Once you have a list of potential solutions for a subproblem, such as configuring the wheels around the passenger in a vehicle design, it's crucial to explore systematically. A tool like the concept combination table can aid in creating a structured process, ensuring all viable solutions are considered.

Throughout the problem-solving process, remember this is not a rigid procedure but a creative exploration. If it challenging to visualize concepts like substitution and income effects, following a structured procedure can be very useful.
