Some of this may come in the form of mathemetical expressions or equations.

Is there a good program that allows for data input for mathematical expressions in the conventional format e.g. indicating X^2 by actually placing the 2 on the upper right side of the X. Or, by indicating the sq rt of a value by writing a radical over the expression.

I noticed the icons at the top of the message field and am experimenting with them, but they seem minimal.

^{X2}

anyway, I'm just trying to find a way to easily (relatively) and clearly indicate mathematical expressions and arguements.

thanks.
