My story with my new friend

One day , I met starnge man . He said that he came from the moon. Then I said to him , what it's your name?. He said " I don't have a name" . Then I gave him a name . It was John. Next month, he said I want know what does Algebra mean ? . Then I it's related to math . I said to him " do want to count anything ? " . Then he laughed , and he said " I want know my vehicle's speed" . Then I said " How many hours it takes from the moon to here" . He said it's X hours. Then I said to him " The distance between the moon and the earth is Y . So if you want to know your vehicle's speed. You must divide the distance by the time, and you can write it like this ( Y/X = your vehicle's speed) " . Then he said "Oh I see" . So he learned a part from math and physics. Then he said " Thanks!" .
THE END
