What the fuck are imaginary numbers? Sounds like some shit a stoner comes up with. "Yeah bro, I'm imagining new numbers". Fuck off

They are called Complex numbers not Imaginary.
Complex numbers consists of "Real" and "Imaginary".Real being the standard number line and Imaginary being the extention into 2d.

$i$ is the formal solution to $x^2 + 1 =0$ . It is the convenient defined object intended to help further the study of polynomials since it shows up all the time, especially in quadratic equations $ax^2 + bx + c =0$ when $b^2 - ac < 0$ .
>>14178880
And an imaginary number is just a complex number with real part equal to zero.

Everything in math is imaginary, abstract. We invent math when it helps us solve problems. Complex numbers help us achieve this, like for example calulating the roots of cubic or modelling periodic functions.

They are not different from any other number or broadly speaking any other abstract concept. The thing is defined by it's properties. Real or Natural Numbers do not exist in material world as well.

"-" is an inverse operator
2 apples + -2 apples = 0 = 2 apples + 2 antimatter apples

-2 apples = 2 antimatter apples

I think of complex numbers not as concrete or especially meaningful things in and of themselves, but only as abstract, intermediate results that allow a sequence of operations to arrive at correct answers.

Imaginary number line is the basis for quaternions, which relates not only to i j k, the common basis vectors. Also some stuff relating said quaternions to the Lorrentz group and Clifford algebra.

Sorry I misread, and you are right. Now I square one more time to get

x*x*x*x*x*x*x*x* = 1

which produces eight octonion solutions. Very neat. Thank you anon.
