Okay kiddo, do you like puzzles? The Fox-Wright function is a way of solving a really tricky puzzle called the "tower of Hanoi."
So imagine you have three big poles, and on one of the poles you have a bunch of different sized disks stacked up on each other, from biggest on bottom to smallest on top. And your job is to move all of these disks over to a different pole, but you can only move one disk at a time, and you can never put a bigger disk on top of a smaller one. It's like a giant game of Jenga, but way harder.
So the Fox-Wright function helps you figure out how many moves it will take to solve the tower of Hanoi puzzle, depending on how many disks you start with. It's a really complicated math equation, but basically it looks at the number of disks and calculates the minimum number of moves you'll need to make in order to solve the puzzle.
Let's say you start with three disks. The Fox-Wright function would tell you that it will take you seven moves to solve the puzzle - that's the minimum number of moves you could make. But if you start with four disks, it will take you 15 moves. And if you start with five disks, it will take you 31 moves!
So basically, the Fox-Wright function is like a secret code that helps you figure out how many moves you'll need to solve the tower of Hanoi puzzle with different numbers of disks. Pretty cool, huh?
