Canon arithmeticus

Okay, so have you ever played with toy blocks? They come in different sizes and colors, right? Well, imagine that numbers are like those blocks, but instead of sizes and colors, they have different meanings.

Now, let's talk about canon arithmeticus. It's a fancy way of saying a system of counting or arithmetic that was used a long time ago. Back then, people didn't have fancy calculators or computers to do their math, so they had to come up with different ways of doing it. Canon arithmeticus was one of those ways.

In this system, numbers are divided into different categories. There are perfect numbers, which are like the coolest blocks - everyone wants them because they have special properties. There are also superparticular numbers, which are made up of smaller blocks put together in a certain way.

One of the things that makes canon arithmeticus different from our modern system is that it relies heavily on patterns and relationships between numbers. For example, if you add up all the numbers from 1 to 10, you get 55. In canon arithmeticus, this would be called a triangular number because it forms a triangle when you draw it out with blocks.

Overall, it's a really interesting way of looking at numbers, and it was used by some of the greatest mathematicians of their time. However, it's not really used much anymore because our modern system of counting and arithmetic is much more efficient and practical.
