Algol 68 is a language that computers use to talk to us. It's like a code that tells the computer what to do. Just like when we give directions to someone, or tell them to do something specific.
Algol 68 is special because it was made to be very precise, kind of like math. It has rules for how things are written and how they work together.
It's kind of like building with blocks. Every block has its own shape and fits together in a certain way. With Algol 68, we can build things that the computer can understand and execute, like playing a game or writing a program to help us do some work.
So, Algol 68 is a language that the computer can understand and follow, like building with special blocks. It helps us tell the computer what we want it to do in a very precise way.
