ELI5: Explain Like I'm 5

Numerary nexus

Okay kiddo, imagine you have a bunch of things like toys, candies, and books. When we count them, we use numbers like 1, 2, and 3 to say how many there are. These numbers are called numerals.

Now let's say we want to group our things based on what they are. We put all the toys in one pile, all the candies in another pile, and all the books in a third pile. Each of these piles is called a nexus.

But what if we want to count how many toys we have in total? We can't just count the number of piles, because there might be more than one toy in each pile. So we need to count the number of toys inside each pile and add them together.

This is where numerary nexus comes in. It means we assign a number to each nexus based on the number of things inside it. For example, if we have 3 toys in one pile, we can call that pile a "3-nexus" because it has 3 things inside it. Then we can do the same for the other piles, creating a "1-nexus" for the pile with 1 candy and a "2-nexus" for the pile with 2 books.

By using numerary nexus, we can count the total number of things we have by adding up the numbers assigned to each nexus. In this case, we have a total of 6 things (3 toys + 1 candy + 2 books). So numerary nexus helps us organize and count our things more easily!
