## Discrete Math Rules—For Your Reference

Below you will find the laws of propositional logic, the rules of inference, and the quantified statements rules of inference presented in a table format.

## Logical Equivalence in Propositional Logic

We need to understand the concept of logical equivalence to better understand the laws or propositional logic.

## Predicate vs Proposition in Logical Mathematics

A predicate is a statement that has variables, such as x + 5 = 12. A proposition does not have variables in its statement, such…

## Universal and Existential Quantifiers

We've seen in Predicate vs Proposition that replacing a function's variables with actual values changes a predicate into a proposition. Another way of changing a…

## Laws of Propositional Logic

The laws of propositional logic help us find logical equivalence between propositions.

The conditional operation is denoted by the arrow symbol →.Q → E reads as "if Q then E.

## Propositions and Logical Operations

In logic, a proposition is a statement that evaluates true or false, such as "all cars are blue" or "4 + 4 = 8." A…

Zend, what do you think of implementing a feature that let's other people proofread articles on this website?
Why is that a good idea?
Seems like an appropriate implementation, I will give it some thought. Thanks
