          In our everyday lives, we come across many situations. Some of these situations
          involve problems that need to be solved. Examples of such problems are getting

          ready for school, baking a cake, making a phone call to a friend, calculating cost of
          whitewashing a house, calculating area of a rectangle, etc.

          PROBLEM SOLVING

          Some of the above problems can involve mathematical calculations, while others
          involve small tasks that need to be done to solve the problem. The process of devising

          a solution to a problem is called Problem Solving.
          Problem Solving involves reasoning and logical thinking. Logical thinking is the ability
          to understand a given problem and develop a series of steps to solve it. Reasoning is

          the ability to analyse and choose the best solution among several possible solutions.
          There are several steps involved in problem solving. These are:

            1.  Identify the problem: This step involves understanding the problem clearly
                  and collecting all required information about
                  it.                                                                            Identify
                                                                                                   the
            2.  Devising  a  solution:  This  step involves                                      problem
                  preparing a series of steps to solve the problem.
                  All possible solutions are pursued and written
                  down.                                                           Implement      Problem       Devising a
                                                                                     the
            3.  Choose  the  best  solution:  This  step involves                  solution      Solving       solution
                  analysing the various solutions and visualising
                  the  effects  of  implementing  each  solution.                                Choose

                  Comparing the results helps choose the solution                                the best
                  that is clear, easy, and safe to implement.                                    solution
