What is Gauss, Legendre algorithm?

Gauss and Legendre came up with a clever way to find square roots, like figuring out what number you multiply by itself to get another number.

Imagine you have a box of chocolates, and you want to know how many rows of chocolates there are if each row has the same number of chocolates. That’s like finding a square root! Gauss and Legendre used a step-by-step guess-and-check method, kind of like playing a game where you get closer and closer to the right answer every time.

They start with two guesses: one that's too high and one that's too low. Then, they take an average of those two guesses and see if it gets them closer to the real square root. It’s like trying to find your way across a room by taking steps that get you halfway there each time, even if you’re not sure where you are yet!

This method is used in computers all around the world when they need to calculate square roots quickly, especially for big numbers. So next time you see something working out a square root, it might just be using this clever guessing trick from Gauss and Legendre!
