Common questions faced while solving problems

What is information on a need-to-know basis?

How do we use the resources at hand to find and solve the problem?

Why do we need to establish distinct problem solving methods?

How do we decide on what the information needed depends?

Mathematical Information

After you see that you need math to solve a problem, you need to get the required math skills to solve it. After you get the math skills, you "test drive" with a couple of problems and then solve the problem at hand.
