"what if we put a Real Number and an Imaginary Number together?" Complex Numbers they are both valid and useful types of Numbers! Real Numbers aren't "in the Real World" (in fact, try to find exactly half of something in the real world!) and Imaginary Numbers aren't "just in the Imagination".
So the names are just a historical thing. And Real Numbers got their name to distinguish them from the Imaginary Numbers. Imaginary Numbers were originally laughed at, and so got the name "imaginary". There are also many applications for Imaginary Numbers, for example in the fields of electricity and electronics. Imaginary Number: A number whose square is a negative Real Number.Īnd i (the square root of −1) times any Real Number is an Imaginary Number.
