Imaginary number - Wikipedia
An imaginary number is the product of a real number and the imaginary unit i, [note 1] which is defined by its property i2 = −1. [1][2] The square of an imaginary number bi is −b2.
Imaginary Numbers - Math is Fun
Imaginary numbers were first introduced by mathematicians in the 16th century to solve equations that seemed impossible. Today, they're used in everything from designing airplanes to creating special effects in movies. Imaginary numbers become most useful when combined with real numbers to make complex numbers like 3+5i or 6−4i.
What Are Imaginary Numbers? - HowStuffWorks
What Is an Imaginary Number? An imaginary number — basically, a number that, when squared, results in a negative number — was first established back in the 1400s and 1500s as a way to solve certain bedeviling equations.

Imaginary unit - Wikipedia
Any real-number multiple of the imaginary unit is called an imaginary number. By combining the real numbers with the imaginary unit using addition and multiplication, a new number system known as the complex numbers is formed; it consists of all numbers of the form a + bi with real numbers a and b.
