Ok kid, let me explain the supergolden ratio to you! You know what a ratio is right? It's when you compare two things like how many apples you have compared to how many oranges you have.
Now, the supergolden ratio is a very special ratio that mathematicians found to be very interesting. It's pretty much like a superhero version of the regular golden ratio.
You know what the golden ratio is, don't you? It's a special number that shows up a lot in nature and art. It's about 1.61803 (but don't worry about that right now). It's like the perfect balance between two things. Kind of like how your nose is the perfect balance between your two eyes!
Now, the supergolden ratio is even more special than the golden ratio because it's like a superhero version of it! It's like the perfect balance between three things instead of just two. It's something like 1.46557 (again, don't worry about the numbers too much).
It's not as common in nature or art as the golden ratio, but it's still really cool to mathematicians because it shows up in some pretty complicated equations. In fact, some people call it the "most irrational number" which just means it's really really really hard to explain or make sense of.
So there you have it kid, the supergolden ratio is like the superhero version of the golden ratio, and it's all about finding the perfect balance between three things instead of just two!
