How do we express logic?

We use symbols and rules to express logic, just like we use words and grammar to tell stories.

Imagine you have a toy box full of blocks, some red, some blue. You might say, "If I pick a red block, then I get a snack." This is a simple kind of logic, where one thing happens because of another. We can write that as:

Red Block → Snack

Now imagine you have two rules:

1. If it's sunny, we play outside.
2. If it's rainy, we read books.

We can use symbols like S for "sunny" and R for "rainy," and write these as:

S → Play

R → Read

This is just like how you might use a map, the symbols are your landmarks, and the rules help you know where to go next. You don’t need magic; you just need symbols and rules, and then you can build whole worlds of thinking!
