Answer to Problem 30LC

Analyzing, calculating, and evaluating are the three steps in solving numerical problems.

Explanation of Solution

The methods for solving numerical problems are arranged into a three-step approach to problem-solving.

This strategy has been proven to be very beneficial and efficient.

Analyzing, calculating, and evaluating are the steps in solving a numerical word problem.

Analyze:

First, establish the starting point (what is known) and the destination (what is unknown) to solve a word problem. A measurement or an equation illustrating the link between measurements could be considered to be what is known. Before performing any calculations, decide what unit(s) the answer (the unknown) should have if it anticipates it to be a number. After separating the known from the unknown, devise a strategy for utilizing the known to reach the unknown.

Planning is essential for effective problem-solving.

Calculate:

Making the calculations is typically the easiest step in the process of creating a successful plan.

Evaluate:

An answer should be evaluated once it has been calculated.

Verify that answer includes the appropriate number of significant digits and the appropriate unit(s).
