# Thread: Odd Notation

1. ## Odd Notation

On the link for complex numbers http://www.freemathhelp.com/imaginary-numbers.html

we say So, i = sqrt(-1), or you can write it this way: -1 1/2 or you can simply say: i 2 = -1.

That notation for exponents is used throughout the link. I do not think that notation is standard. If it is a standard, it is so seldom used that I believe it will be hard for students to understand.

2. No, that is not standard notation for exponents.

It looks like a case where copy-and-paste was not able to hold onto the superscript coding in the original.

Ted will need to manually reformat those missing superscripts.

Thank you for pointing it out.

3. Unfortunately, "Free Math Help" is notorious for bad formatting and, sometimes, simply wrong information.
