Okay, let's say you have a bunch of toys and you want to put them in a box. But the box has a limited space, so you have to be careful how you arrange the toys. This is kind of like how Go works.
In Go, you have a board with a bunch of spaces on it. You and your opponent take turns putting pieces, called stones, on the board. The trick is that you have to be careful where you put your stones, because they can help you control more spaces on the board or they can get in the way of your opponent.
Now, the math part comes in with the scoring. At the end of the game, you count up how many spaces you and your opponent have controlled with your stones. This is kind of like counting how many toys you were able to fit in the box.
But there's a bit more to it than that. You see, some spaces are more valuable than others. And sometimes you can surround your opponent's stones, which makes them trapped and unable to control any spaces at all. So you have to use a bit of math and strategy to make the most of your stones and score the most points.
