TeX Math

SevenMark uses dollar delimiters for TeX math.

Inline Math

Inline math uses a single dollar delimiter and cannot cross a line break.

The famous equation $E = mc^2$ was discovered by Einstein.
The quadratic formula is $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$.

Block Math

Display math uses double dollar delimiters. Newlines are preserved inside the math value.

$$
E = mc^2
$$

$$
\sum_{i=1}^{n} i = \frac{n(n+1)}{2}
$$

Common Notation

Addition: $a + b$
Subtraction: $a - b$
Multiplication: $a \times b$ or $a \cdot b$
Division: $\frac{a}{b}$

Superscript: $x^2$ or $x^{10}$
Subscript: $x_i$ or $x_{ij}$
Combined: $x_i^2$

Greek letters: $\alpha, \beta, \gamma, \delta, \theta, \pi, \sigma$

In Tables and Lists

Namumark Compatibility

SevenMark also accepts Namumark TeX forms and maps them to the same TeX AST:

[math(x^2 + y^2)]

<math>
x^2 + y^2
</math>

[math(...)] is inline unless the math value contains a line break. The formatter normalizes TeX output to $...$ or $$...$$.

Notes

• The old {{{#tex ...}}} form is no longer TeX syntax.
• Use $...$ for inline math and $$...$$ for display math.
• TeX content is raw text; SevenMark markup inside math is not parsed.
