What are imaginary numbers?? I have heard of them before, and I know it is a really high level of math, but can somebody explain it to me?? I'm only taking Alg 1 right now! lol

Imaginary numbers are a way to explain how impossible equations have answers. [ Drama_Secretary's advice column | Ask Drama_Secretary A Question ]
RoadkillSalad answered Saturday February 19 2005, 10:30 pm: It's a number that's not technically possible, and it usually involves the square root of a negative prime number. For example, the square root of -1 is impossible because a negative multiplied by a negative will never equal a negative. The square root of -1 is commonly used as the letter "i" to simplify things. So the square root of -5 can be simplified by stating it as "i times the square root of 5." It's hard to explain, and it's pretty hard to understand, but you will probably have to work with them at some point in time or another, so there you go.

It's sort of hard to explain this but if you go to [Link](Mouse over link to see full location) and search for imaginary numbers, you can find out more information.
