Mathematical reasoning is a part of mathematics where we determine the truth values of the given statements. In terms of mathematics, reasoning can be of two types. In the Inductive method of mathematical reasoning, the validity of the statement is checked by a certain set of rules and then it is generalized.
The principle of mathematical Induction uses the concept of inductive reasoning. On the other hand in Deductive reasoning, we apply the rules of a general case to a given statement and make it true for particular statements.
This is actually opposite of the principle of induction. Consider the following Statement: The sum of two prime numbers
Validating statements in mathematical reasoning exercise always even. The given statement can either be true or false. Such statements are mathematically not acceptable for reasoning as this sentence is ambiguous. For deducing new statements "Validating statements in mathematical reasoning exercise" for making important deductions from the given statements two techniques are used generally:.
In this method, we generate new statements from the old ones by the rejection of the given statement. In other words, we deny the given statement and express it as a new one. Consider the following example to understand it better:.
Here by using not, we denied the given statement now the following can be inferred from the negation of the statement:. This is a false statement as squares of two natural numbers will be positive. From the above discussion we conclude that if 1 is a mathematically acceptable statement then negation of 1 denoted by 2 is also a statement. With the help of certain connectives we can club different statements.
Such statements made up of two or more statements are known as compound Validating statements in mathematical reasoning exercise. These connectives can be and ,or etc. With the help of such statements the concept of mathematical deduction can be implemented very easily. These both statements are mathematically true. Now it would be clear to you how to use compound form of statements and negative of a statement to deduce results. To learn more on this topic, download Byjus-the learning app.
