spaces in inline formulae
\(a\;b\) semicolon
\(a\:b\) colon
\(a\,b\) comma
\(ab\) juxtaposition
\(a\!b\) exclamation
inline frac!
\(a/b\) solidus
\(\frac{a}{b}\) frac
\(\dfrac{a}{b}\) dfrac

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

Code:


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.

Bullets

• first item
• second item
  

Numbers

1. unnumbered item
2. anonymous item
3. semi last item

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.
