Problem Solving Steps to solve problems Understand. Plan - Solve a simpler related problem. Do it. Check it. Solving a Simpler Related Problem When faced with a problem that appears complicated,you may find it helpful to first solve one or more similar problems that have simpler conditions. Solutions of simpler problems may lead to the solution of the more difficult problem. Example 1. Count how many rectangles are there in the figure?

Example 2. How many triangles do you see? 5 Small Triangles.(l + l + l + l + l) 1 Big Triangle. 6 Triangles inside.(BDE,DEC,BDC,CBE,ABE,ACD) So we have 6 + 5 + 1 = 12 Triangles in all. Solving a simpler problem sometimes involves substituting more manageable numbers into the problem. Example - You have 7 1/2 feet of ribbon.Each foot of ribbon can make 4 bows.How many bows can you make from 7 1/2 feet of ribbon.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
