Relevant logic is a special kind of logic that helps us talk about things that are relevant or important to a particular situation or problem.
Imagine you want to make a sandwich for lunch. Relevant logic helps you focus on the things that actually matter for making a sandwich, like bread, cheese, and meat, instead of things that don't matter, like the color of your socks.
In relevant logic, we use rules to determine which things are relevant or important to a particular situation. These rules help us decide which facts or pieces of information we should pay attention to and which we can ignore.
For example, if you are trying to solve a math problem, relevant logic helps you focus on the information and formulas that are relevant to solving that problem, while ignoring information that is not necessary or important for finding the answer.
Overall, relevant logic is a special tool that helps us make better decisions by focusing on the things that really matter and ignoring the things that don't.
