Sounds like ... ghost-hunting ! Or, in physics, .... "negative" energy, or particles having "imaginary" mass (tachyons). Or, in mathematics, imaginary straight-lines being perpendicular to ... themselves. Or, always in math, varieties with an infinite number of dimensions (Hilbert?). Or, very modern subject indeed, physical bodies with a "fractal extension" (Mandelbrot?), like the length of the coast of Brittany, which is not ... a length, otherwise it will be ... un-determinate .

Yes, "minusation" . What about "+- imagination", then? Nice word, anyway. May be we can get "+-imagination" by equalling multiplication and "addition" to "zeration"?

That would lead to "multiplication" becoming equal to "minusation" and that would only be possible if somehow inside multiplication we had "+-imagination"???

Or actually, instead of multiplication.
