Hi, I am wondering if there is a way to include subscripts or superscripts in Daniweb?

I just answered a question about polynomials and it would have been nice to have more math symbols available to discuss math-related topics when they come up.

For example, instead of writing a polynomial as follows:

a0*x^0 + a1*x^1 + a2*x^2 + a3*x^3 + . . .

it would have been nice to write it with the proper subscripts and superscripts. I tried to use HTML code (<sub> and <sup>), but that didn't work. Am I overlooking something?

Also, another bit of annoying behaviour: when the line above is not wrapped in code tags, the '*' sign is removed and the characters are pushed together. For example, a2*x^2 becomes a2x^2 when the post is actually posted. Is there a way to stop this behaviour?

Not presently. When we were using vBulletin as the back end we allowed TeX formatting, but it was very much unused.

Yup, straight HTML isn't allowed in our editor for various good reasons. ;)

Yes, the * character has special meaning for Markdown, our formatting language. You can escape them with a backslash to disable parsing as a bold or italic starter character: \*

Probably that what you wrote above is understandable and easier to write than using special commands to super- and subscript.

No, I don't think you're overlooking anything.

a0x^0 + a1x^1 + a2x^2 + a3x^3 + . . . Normal

a0*x^0 + a1*x^1 + a2*x^2 + a3*x^3 + . . . Inline Tags

a0*x^0 + a1*x^1 + a2*x^2 + a3*x^3 + . . .  Code Tags

I see what you mean. Use Inline Tags since it is essentially code
