Composition ring

A composition ring is like a special type of toolbox where you can add, subtract and multiply different tools together to make new ones. Just like how you can add a screwdriver and a hammer to make a tool that can both hammer and screw, you can add and multiply different elements in a composition ring to make new ones.

But in a composition ring, there are some rules you have to follow. For example, if you add two tools together, you might not always get a new tool. In a composition ring, you have to make sure that the tool you get when you add two elements is still in the toolbox. If it’s not, then it’s not in the composition ring.

Also, when you multiply two tools together, you have to make sure that the answer makes sense. For example, if you multiply a screwdriver and a hammer, you might get a tool that’s useless, like a screwdriver-hammer hybrid that’s too heavy to use. In a composition ring, you have to make sure that the result of multiplying two elements still makes sense and follows the rules of the composition ring.

Overall, a composition ring is like a toolbox where you can add and multiply different elements together to make new ones, but you have to follow some special rules to make sure that the new elements you make are still in the toolbox and make sense.
