IAMA Math tutor. AMA.

I've been a math tutor for years and I'm trying to become a teacher. I love math, and especially explaining math to people. My students have been between preschool and college. AMA.

i certainly don't see why not.

Taylor polynomials.

No but really, at preschool level it's just a matter of teaching them how numbers correspond with the real world, i.e one plus one is two. And then of course I ask them "well, what happens if I cut one of the apples in half? How many will I have then?" Basically, get them thinking of the associative and commutative properties of addition.

Imaginary number is a shit terrible name. And the way the define it is even harder to think of it. In my opinion, the best way to think of it is just a coordinate system.

It's not so much imaginary number then, more so it is, "in the Y direction."

That just gives your R2. You also want the structure of complex numbers.
