Mathematical induction to the correctness of the formulas of the inspection of the application of also has the very big. Mathematical induction into the limited is infinite bridge, mainly discusses the relevant proposition about natural number set or identities, Mathematical induction has wide application in middle school mathematics，such as ,the problem of division,the proof of identity,the proof of axiom,permutations and combinations,geometry.here we main combination junior middle school teaching material to a detailed list mathematical induction in the middle school mathematics application .To the application of mathematical induction skilled, we must first accurately understand its significance and skilled The master problem-solving steps, and in three steps into the use of assumptions is particularly critical, the use of assumptions summarized introduced guess the most important. In the end we proved that by using a simple mathematical induction identities in the process, can more deeply understand and master, summed up - guess - prove this discovery to explore ways of thinking.
