And for the record, the Fibonacci sequence can be defined as a naturally occurring series in nature.
It is irrational, imaginary and transcendental numbers which cannot be defined.
I don't see how a simple mathematical calculation ( 2+2=4 ) cannot be fully explained by an
individual. Although larger issue are trickier to explain single-handedly.
Don't forget to explain who made it, its history, how it came to be, when it was developed etc. That is what I mean. You just explained one itty bitty little fraction of 2+2=4.
