Any suggestions for math equation editor?

I think it will take more practice. I was having trouble with a fraction that had exponential. I figured I had to put exponential symbol first, then make one of those the fraction. Even more complicated is the fraction with an exponential fraction... I have shortcuts now in tool bar which is helping. Still think pen and paper is easier! Thanks for the feedback!

You should be able to write out most of your symbolic working using a keyboard but getting around the format is the tricky bit.

You have the usual symbols +, -, /, *
Exponential ^
Subscript _
You can make judicious use of bracketing (), [], {}

If you provide a rough key, you have quite a bit of freedom if it's a person marking the paper, for example:

(3x^2)[xy+z^(1/2)]=0
1/[sin^2(cos(2xpi/9)]=e^x
abs(x>4)=3
16mod3

Completely agree that pencil and paper is way better! Apologies if any of this is gobbledygook but hope it helps.
