Study Notes
Reasoning
- Reasoning is the process of drawing conclusions or inferences from facts or premises.
- Both logic and reasoning are associated with problem-solving and critical thinking.
- There are two types of reasoning: Inductive and Deductive.
Inductive Reasoning
- Inductive reasoning is the process of reaching a conclusion based on a series of observations.
- It involves forming generalizations based on the examination of specific examples, instances, or events.
- A conclusion may or may not be a valid one.
Deductive Reasoning
- Deductive reasoning is the process of reaching a conclusion based on previously known facts.
- The conclusions reached are correct and valid.
- It draws a specific conclusion from general principles or premises.
- It forms generalization based on already established or agreed assumptions, laws, procedures, and laws of logical reasoning.
Proof
- A piece of information that shows something exists or is true.
- It can also be considered as a piece or pieces of evidence.
- In mathematics, a proof is a sequence of statements that explain why a mathematical statement is true.
Mathematical Proof
- A mathematical proof is a collection of statements arranged logically that explains why a math statement is true.
- It demonstrates the validity or truth of mathematical statements.
Mathematical System
- A mathematical system consists of math objects, their definitions, and descriptions of relations among them.
- A mathematical system includes axioms, assumptions about objects that do not require a formal proof, and rules of logical reasoning.
- Theorems in a mathematical system are statements resulting from logical reasoning and assumptions about its objects.
