Disjunction introduction

Okay, kiddo, let me explain what disjunction introduction means.

Disjunction is a big word that means "either A or B." For example, let's say you have two toys, a car and a teddy bear. You can either choose to play with the car or the teddy bear - but not both at the same time. It's either one or the other.

Now, disjunction introduction is like showing off your toys to your friend and telling them you have two options. You say, "Either I can play with my car OR my teddy bear."

This is a way of introducing the idea that you have two choices - and you will only choose one of them.

In logic, disjunction introduction is a way of introducing a statement that says "either A or B." It's like saying "I have two options - A or B." This statement is useful in proving some arguments, because it sets up two choices that can be analyzed and compared.

So, that's disjunction introduction in a nutshell! It's a way of introducing a statement that says there are two options - and only one of them can be true.
