Okay, imagine you have a group of friends and you all want to go see a movie together. You can't all talk at the same time because it would be too confusing. So you come up with a plan to take turns talking.
Galibi order is like that plan. It's a way that a group of people, like scientists or mathematicians, can take turns talking in a very specific order. This way, they don't talk over each other and everyone gets a chance to share their ideas.
The order is named after a mathematician named Joseph Louis Lagrange, who came up with the idea a long time ago. It starts with one person, and then goes around the group in a certain pattern. So, it's like a game of hot potato, but with talking about math or science.
When people use galibi order, they can work together better and things get done faster because they're not confused and talking over each other. It's a way to make sure that everyone has a chance to be heard and contribute their ideas.
