Homonym: Deduction (Tax)
Deduction is a logical process where conclusions are drawn from general principles or premises. It involves starting with a broad statement or theory and applying it to specific cases to reach a conclusion. For example, if we know that all humans are mortal and that Socrates is a human, we can deduce that Socrates is mortal.
In mathematics, deduction is often used to prove theorems. By applying established rules and definitions, mathematicians can derive new truths. This method is essential in fields like philosophy and science, where logical reasoning helps validate theories and arguments based on existing knowledge.
