Answer:
It's important to know if the solution is correct, or if there's another way to solve correctly and more efficiently.
Step-by-step explanation:
Evaluation is a process through which we critically examine a program, task, research or any kind of job.
In this case, when we use the problem solving method, we apply an evaluation step. This part of the process is really important, becuase it allows you to know if your results where correct, if it was efficient, or maybe there's another way to solve the problem with lowers costs.
So, basically, we analyse the information provided by the problem and its solution, to see its efectiveness.
