Q-category
Okay kiddo, imagine you have a bunch of toys - maybe some blocks, stuffed animals, and cars. And you also have some special rules for how you can put those toys together. Maybe you can only stack the blocks in a certain way, or the cars can only move in straight lines.
Now imagine that instead of toys, we have math things like numbers and equations. And instead of rules for putting the toys together, we have rules for combining the math things in certain ways. That's what something called a "q-category" is all about.
A q-category is a way to organize a bunch of math things and how we can put them together in specific ways. It's like a special kind of toybox for math things! And just like we have toys that can only move or fit together in certain ways, certain math things in a q-category can only be combined in certain ways too.
For example, let's say we're looking at a q-category where the math things are just numbers, and the rule for putting them together is multiplication. In this q-category, we know that if we have the numbers 2, 3, and 4, we can multiply them together in any order we want and we'll always get the same answer: 24. That's because multiplication is "associative" - it doesn't matter which order we do it in.
But if we have a different q-category where we're combining equations instead of numbers, maybe the rule for putting them together is completely different. We might have to follow a rule like "equations with the same variable can be added or subtracted, but equations with different variables can't be combined at all." That's a completely different way of combining things, but it's still an example of a q-category.
So basically, a q-category is a way to organize math things and the rules for combining them, kind of like a toybox for numbers and equations. And just like we have to follow certain rules for how we play with our toys, we have to follow certain rules for how we combine the math things in a q-category.
