X^4-6^ were better.

I never knew Yoda was such an accomplished mathematician...
Tbf it can sometimes be difficult to understand him
Clever
Don’t be so positive.
My group theory teacher:
"Always two, there are [except in the degenerate case where a = 0]."
What are you, IEEE floating point? https://en.wikipedia.org/wiki/IEEE_754
Edit: actually read the negative zero article and saw IEEE floating point mentioned.... kinda kills the joke
"Minus zero" redirects here; not to be confused with Godzilla Minus Zero.
Well thanks Wikipedia!
You dare speak of the degeneracy!? 🤪
You just spoke the "|" in "|X| = 3" silent.
That additionally would imply an uncountably infinite set of complex solutions.
Why assume the solution is in the complex numbers, and not in
- the real numbers (2 solutions)
- the algebraic numbers (countably many)
- the natural numbers (1 solution)
- the complex surreal numbers (proper-class many)
Gotta use some context to interpret these things :)
Well it's not physics. Show 'em what happens when you don't specify those kinds of things.
I don't think teachers need to specify that answers should be in the largest class of numbers students have been introduced to so far at school :)
If students are smart and motivated enough to learn about other stuff outside of school, they're smart enough to interpret the question.
It's so unnatural...
Another, there is*
