Bump (union)

Okay kiddo, imagine you like to build towers with Legos, and you have a red Lego and a blue Lego. Now, you want to put them together and make a bigger tower. When you stack them on top of each other, they become a BUMP. Just like that, two things coming together in a very specific way can be called a bump.

In big boy words, a bump union is a mathematical concept where two things or sets come together in a way that you can tell which things or numbers belong to which set. For example, if we have set A with the numbers 1, 2, and 3 and set B with the numbers 3, 4, and 5, we can put them together with a bump union. The result would be a new set with all the numbers from both sets, but we'd keep the duplicates. That means the set would look like this: {1, 2, 3, 3, 4, 5}.

So, just like you could stack your Legos together to make a bump, we can stack sets together to make a bump union. It's like building with math Legos!
