Why is it called a SQUARE root?

I explain why it is called a square root, and also how a square root works. #mathematics #DoS Clarifications: To keep this video simple I decided to not talk about complex numbers. But perhaps I should have mentioned complex numbers when talking about the square root of negative numbers. When I said "you can never have a square root of a negative number", I guess I could have said "you can never have a square root of a negative number, unless you use complex numbers." Cool, well I'm still learning! And thanks for keeping me in check. :D Also, if you like my videos you might like my books, featuring Professor Astro Cat.
