What is unification?

Unification is when two or more things become one by finding what they have in common.

Imagine you're playing with building blocks. You have a red block and a blue block. At first, they look different, one is red, the other is blue. But if you find out that both are square blocks, you can put them together because they match in shape, even though their color is different.

Sometimes, unification works like learning a common language. Suppose two friends want to play a game but speak different languages, one speaks English, the other speaks Spanish. They can still play if they both learn to say "hello" in the same way, like using hand signs or a new word they both agree on.

Think of it like sorting toys. If you have big trucks and small cars, but they’re all vehicles, you can group them together, even though they're different sizes. You’ve unified them by their type instead of their size.

Unification is just finding the things that are the same so everything can work together, like your blocks, your friends, or your toys!
