Maybe you've never been given as "step by step" for the problem solving process.
Step 1: Set aside your math anxiety and turn on your brain. (The number at the top of the answer is intended to help you do that.)
Step 2: Read the problem statement, interpreting it according to your experience in the real world and your knowledge of English words and sentence structure.
Step 3: Identify what the problem statement is telling you.
Step 4: Identify what the problem statement is asking you.
Step 5: Apply your knowledge of real-world relationships and math relationships to determine how the asked-for information is related to the given information.
Step 6: Use logical reasoning, and/or math symbols to write any down any relationships (equations or inequalities or diagrams) that need further manipulation to achieve the desired answer.
Step 7: Solve those equations, logic problems, geometry diagrams, whatever, using the math relationships you have learned.
Step 8: Relate the solution(s) you found to the question that is being asked. (This may require additional steps.) Note that this is what is being done in the bold statement at the end of the answer above.
