The main emphasis of Chapter 14, Mathematical Reasoning in the NCERT Exemplar Class 11 Maths, is logical skills and reasoning. Use of proper logical operators such as "and," "or," "if-then," and "neither-nor" is discussed, as well as various types of statements such as simple and complex statements. Conditional statements, their converse, inverse, and contrapositive, and how to prove their validity using truth tables are discussed in this chapter. Quantifiers that help students understand logical phrases, such as "for all" and "there exists," will also be taught to them. An introduction to mathematical induction is also included. These subjects help develop critical thinking skills, problem-solving abilities, and the ability to formulate and support mathematical claims.
