Okay, so imagine you want to tell a computer what to do, like drawing a square. But you can't just say "draw a square," because the computer doesn't speak English or any other language we use.
So people made up different languages that the computer can understand, called "programming languages." Algol X is one of them. It's like a secret code that only computers and programmers know how to read.
Now, imagine you want to teach someone how to play a game, like chess. You would need to explain the rules in a certain order and with certain words, right? That's what programming languages do, they give you a way to tell the computer what to do in a very precise order.
And just like in chess, there are different ways to play and different strategies to use. That's why there are different programming languages like Algol X. It's all about finding the right tool for the job.
So basically, Algol X is a language that tells computers what to do, so they can do things like draw pictures or play games. It's like a secret code that you have to learn in order to talk to the computer.
