## What is mathematical logic and examples?

There are many examples of mathematical statements or propositions. For example, 1 + 2 = 3 and 4 is even are clearly true, while all prime numbers are even is false….Propositional Calculus.

X ∨ (Y ∨ Z) = (X ∨ Y) ∨ Z | x + (y + x) = (x + y) + z |
---|---|

X ∧ (Y ∨ Z) = (X ∧ Y) ∨ (X ∧ Z) | x × (y + z) = x × y + x × z |

## What are the types of mathematical logic?

Mathematical logic is divided into four parts:

- Model theory.
- Proof theory.
- Recursion theory, also known as computability theory.
- Set theory.

**Who discovered logic?**

Aristotle was the first logician to attempt a systematic analysis of logical syntax, of noun (or term), and of verb. He was the first formal logician, in that he demonstrated the principles of reasoning by employing variables to show the underlying logical form of an argument.

Logic is based on various fundamental concepts. It studies arguments, which are made up of a set of premises together with a conclusion. Premises and conclusions are usually understood either as sentences or as propositions and are characterized by their internal structure.
