Deductive Reasoning and Inference Rules
A prominent class of theorists suggests that deductive reasoning is dependent upon a specific framework of inference rules.
Nature of Inference Rules
These theorists argue that the rules governing deduction are formal. This means the validity of a deduction depends on its logical structure, irrespective of the actual meaning or content of the statements involved.
Analogy to Logical Calculus
The functioning of these formal inference rules is likened to the operations within a logical calculus. Logical calculus provides a system where symbols and their combinations are manipulated according to defined rules to derive conclusions, mirroring the formal process of deductive reasoning.
Thus, deduction is understood to rely on formal rules of inference, comparable to those found in logical calculus.
Important Questions from Reasoning
Some even numbers such as 6, 8, 24, 28, 32 and 46 are given. If you ask your students to sum any two even numbers given, then in each case they will get an even number. Therefore, by studying the various uses of this type, we can conclude that the sum of any two even numbers is always even. What kind of logic do we observe from the above statement?
I. Inductive reasoning
II. Deductive Reasoning

Ramesh went 15 m to the east, then he turned left and after \(5\sqrt 3 \) m turned 120° right and went \(10\sqrt 3 \) m and then turned 120° right and went \(20\sqrt 3 \) m. How far was Ramesh from the starting point ?
