The mechanical approach to math problem solving relies heavily on manipulation of terms using low level mathematical constructs without using the problem solving abilities of the student. In this problem we have highlighted the possibility to solve a problem in many ways and also the application of less facts and more procedures approach, both working towards improving the general problem solving skills of the student...
