Ok, ok, I HAVE a problem.

Something happened to my uncle(Wally's dad). He works at a factory, and today his hand got caught in the machinery. [reminded of Monkey's Paw] His palm was sawed through vertically. He had surgery done and won't be able to hold a fist for six months.

I wasn't very close to him, but this kind of stuff still bothers you.

And this morning... Ebu taught us that you cannot root a negative number, but in reality, what you do is find the positive root and put i(imaginary number) next to it. Doing so states that you are multiplying the imaginary(impossible) number, root negative one, to the number.

EX
you are to find the root of negative four.
√(-4)

What you put is two(the root of four) and multiply it by i(imaginary).
2i
(i = √(-1)

This means you get root four multiplied by root negative one.
√(4) X √(-1)

Resulting in root negative four!
√(-4)

Mr. Ebunilo said that he never heard of that and was probably some crazy thing came up by the 'math people.'

Well you know what? I learned that from Kumon, and imaginary number has been there since a looong time ago.

A while ago, a student complained about why we can't use scan-trons like all the other classes. Ebu's reply was that scan-trons are SO last century, this is the twenty-first century, we have to be up to date, so we use eInstruction.

Up to date my ass. -.- You're an algebra teacher and never heard of imaginary numbers? That's Algebra II! GOD!

You shouldn't teach people something they'll never comprehend.
Like Algebra teacher and imaginary numbers.
