mean \( \bar {x} = \frac{1}{n}\,\sum_{i=1}^{n}x_{i} \) and standard deviation \( \mathsf{s}_{x} = \sqrt{ \frac{ \sum x^2 - (\sum x)^2 / n }{ n -1 } } \)

Unicode in text: √x a→b x↔y x×y x÷y Σx² 2πr x≤y x≥y


and in code: √x a→b x↔y x×y x÷y Σx² 2πr x≤y x≥y

Fonts for inline operations display:
default √x a→b x↔y x×y x÷y Σx² 2πr x≤y x≥y
vs. Trebuchet MS √x a→b x↔y x×y x÷y Σx² 2πr x≤y x≥y
vs. Courier √x a→b x↔y x×y x÷y Σx² 2πr x≤y x≥y.
It seems that the font used for code sections is not available inline, but Trebuchet is more legible than default or Courier.

Does not work. Leading blanks are eliminated and so are multiple blanks.

Inline HTML: according to daring fireball HTML tags can be inlined into markdown by separating them by blank lines. This does not work. MyBB markdown is different. Neither do LaTeX tables.
\(x+\dfrac{x}{x+\dfrac{x}{x+\dfrac{x}{x}}}\) = \(x+\cfrac{x}{x+\cfrac{x}{x+\cfrac{x}{x}}}\)

The left expressions uses only dfrac. The right expression uses only cfrac. The only difference in the result is the vertical spacing.
