NCERT Solutions for Class 11 Maths Chapter 14 Mathematical Reasoning deals with the most basic math concepts based on logic and reasoning. The mental ability to reason is one of the most important assets of the human brain that makes it superior to other species. This chapter elaborates the process of mathematical reasoning. There are basically two types of reasoning– inductive and deductive. Inductive reasoning is a generalization based on observation whereas deductive reasoning is a hypothesis of whether a statement is true or false under specific conditions.

Aristotle (384 B.C.-322 B.C.) was the first to write a treatise on logic. His study was based on the collection of rules for deductive reasoning which served as a basis for other branches. Another German mathematician named G. W. Leibnitz in the seventh century introduced the symbols in logic. In the nineteenth century, the English mathematician George Boole(1815–1864) and Augustus De Morgan (1806–1871), founded the modern subject of symbolic logic.

# List of Formulas in NCERT Solutions Class 11 Maths Chapter 14 – Mathematical Reasoning

Understanding concepts is a sure shot way to gain a clear understanding of a topic. This chapter does not consist of any formulas rather it simulates a child’s mathematical acumen. students have to use logic to draw sensible conclusions. NCERT Solutions Class 11 Maths Chapter 14 will help students gain deep knowledge of all topics with ease. Some of the important terms, formulas, and concepts related to Mathematical Reasoning explained in these solutions are listed below:

• Mathematical Reasoning: Mathematical reasoning is a critical skill that enables students to analyze a given hypothesis without any reference to a particular context or meaning.
• Statements: A sentence is called a mathematically acceptable statement if it is either true or false but not both.
• Compound statement: A compound statement is a statement made up of two or more smaller statements called component statements of the compound statement.
• Deductive Reasoning: Deductive reasoning, also deductive logic, is the process of reasoning from one or more statements (premises) to reach a logical conclusion.

## A Few Points on Chapter 14 Mathematical Reasoning

• A mathematically acceptable statement is a sentence which is either true or false.
• The negation of a statement p: If p denotes a statement, then the negation of p is denoted by ∼p.
• A statement is a compound statement if it is made up of two or more smaller statements. The smaller statements are called component statements of the compound statement.
• The words “And”, “Or”, “There exists”, and “For every” exist in compound statements.
• The implications are “If ”, “only if ”, and “ if and only if ”.
• The contrapositive of a statement p ⇒ q is the statement ∼ q ⇒ ∼p. The converse of a statement p ⇒ q is the statement q ⇒ p. p ⇒ q together with its converse gives p if and only if q.
• The following methods are used to check the validity of statements: (i) direct method, (ii) contrapositive method, (iii) method of contradiction, and (iv) using a counter-example.
