Hi there! Do you know what a running race is? It's when people run as fast as they can to see who can finish first. Well, a "ran space" is a little bit like a running race, but instead of people, it's about numbers.
Imagine we take the numbers 1, 2, 3, 4 and 5. Now, instead of having a race where they run, we can say that they "ran" a race, but they didn't move anywhere. A "ran space" is just a fancy way of talking about all the different ways those numbers could have finished the race.
You can think of a "ran space" as a big playground where numbers play around and race against each other. But instead of seeing who is faster, we're interested in seeing how the different numbers line up at the end of the race. It's like a giant experiment where we want to know all the different ways the numbers could finish the race.
So, to sum up, a "ran space" is a big playground where numbers "run" races against each other, but instead of seeing who wins or loses, we're interested in exploring all the different ways the numbers could finish the race.
