Delta set

Imagine you have a group of toys, like blocks, and you want to see which ones are different from each other. You start by comparing one block to another and noticing any differences. Then you compare that same block to the next one, and so on. This process is called a delta set.

In math, a delta set is a way of comparing two or more sets of data to see what differences or changes occur between them. You can think of it like comparing two pictures of a park, where one is taken in summer and the other in winter. By looking at both pictures, you can see the changes that happened between the two seasons, like the leaves on trees and the snow on the ground.

So, a delta set helps us identify changes between sets of data, and this can be useful in many applications, like analyzing financial data or tracking changes in the environment. In simple terms, a delta set is just a way of comparing things to see what's different.
