From electrical engineering to quantum mechanics, imaginary numbers are integral in solving complex equations and models that would otherwise be impossible to approach with only real numbers.

Insider Info Historically, complex numbers were developed from examining the real number line. If we think of a real number as a point on the line, then the operation of multiplying by ( – 1) rotates ...

The same process works in the complex plane for multiplication by a positive number: 3 times 2 + 2 i = 6 + 6 i. To multiply by a negative number on the number line requires you to first multiply by ...
