“Principle of Mathematical Induction” is a specific technique used to prove certain mathematically accepted statements in algebra and in other applications of Mathematics, such as inductive and deductive reasoning. The chapter, Principle of Mathematical Induction, students can understand deductive reasoning with suitable examples and mathematical induction is explained with a real-life scenario. Chapter covers a number of topics that includes the process of proving the induction and motivating the application by looking at natural numbers as the least inductive subset of real numbers. Problems related to the Principle of Mathematical Induction, along with its simple applications are covered in the exercise given in the chapter.
