MTH 121—Chapter 1.2 Three More Strategies Problem-Solving Strategies Solve a Simpler Problem Make a List Look for a Pattern The  Solve a Simpler Problem  strategy is often used in conjunction with  Make a List  and  Look for a Pattern  strategies.  Solving a simpler problem reduces the size of the problem, making  it easier to handle.   Patterns emerge once a list of the results is created.  These patterns suggest a  solution to the entire problem. Example: Eight people meet at a party.  They all exchange handshakes.  How many handshakes  are exchanged? Solve a Simpler Problem :   Three  people shake hands.
