8Solving Numeric Problems 1.4Solving Numeric ProblemsAnalyzeTo solve a word problem, you must first determine where you are starting from (identify what is known) and where you are going (identify the unknown).After you identify the known and the unknown, you need to make a plan for getting from the known to the unknown.
9Solving Numeric Problems 1.4Solving Numeric ProblemsCalculateIf you make an effective plan, doing the calculations is usually the easiest part of the process.EvaluateCheck that your answer is reasonable and makes sense. Check that it has the correct unit and the correct number of significant figures.
