Simple inline math
.
$$1+1 = 2$$

.
<p><math><mrow><mn>1</mn><mo>+</mo><mn>1</mn></mrow><mo>=</mo><mn>2</mn></math></p>
.


Simple block math
.
$$$
1+1 = 2
$$$
.
<math display="block"><mrow><mn>1</mn><mo>+</mo><mn>1</mn></mrow><mo>=</mo><mn>2</mn></math>
.


Like other inline markup, whitespace immediately after opening is not allowed
.
foo$$ 1+1 = 2$$ bar
.
<p>foo$$ 1+1 = 2$$ bar</p>
.


Neither is whitespace immediately before closing
.
foo $$1+1 = 2 $$bar
.
<p>foo $$1+1 = 2 $$bar</p>
.


No whitespace before and after is fine though
.
foo$$1+1 = 2$$bar
.
<p>foo<math><mrow><mn>1</mn><mo>+</mo><mn>1</mn></mrow><mo>=</mo><mn>2</mn></math>bar</p>
.

Same goes for punctuation
.
foo$$-2x < 4$$bar
.
<p>foo<math><mrow><mo>-</mo><mn>2</mn><mi>x</mi></mrow><mo>&lt;</mo><mn>4</mn></math>bar</p>
.

Paragraph breaks are unnecessary before and after display math
.
foo
$$$
x + y
$$$
bar
.
<p>foo</p>
<math display="block"><mi>x</mi><mo>+</mo><mi>y</mi></math>
<p>bar</p>
.


Paragraph break in inline math is not allowed
.
foo $$1+1

= 2$$ bar
.
<p>foo $$1+1</p>
<p>= 2$$ bar</p>
.


Neither is an end of document
.
foo $$1+1 = 2
.
<p>foo $$1+1 = 2</p>
.


Inline math with apparent markup
.
foo $$1 *i* 1$$ bar
.
<p>foo <math><mn>1</mn><mo>·</mo><mi>i</mi><mo>·</mo><mn>1</mn></math> bar</p>
.


Display math with apparent markup
.
foo

$$$
1 *i* 1
$$$

bar
.
<p>foo</p>
<math display="block"><mn>1</mn><mo>·</mo><mi>i</mi><mo>·</mo><mn>1</mn></math>
<p>bar</p>
.


Block math can be indented up to 3 spaces
.
   $$$
   1+1 = 2
   $$$
.
<math display="block"><mrow><mn>1</mn><mo>+</mo><mn>1</mn></mrow><mo>=</mo><mn>2</mn></math>
.


But 4 means a code block
.
    $$$
    1+1 = 2
    $$$
.
<pre><code>$$$
1+1 = 2
$$$
</code></pre>
.


Multiline inline math
.
foo $$1 + 1
= 2$$ bar
.
<p>foo <math><mn>1</mn><mo>+</mo><mn>1</mn><mo>=</mo><mn>2</mn></math> bar</p>
.


Multiline display math
.
$$$

  1
+ 1

= 2

$$$
.
<math display="block"><mn>1</mn><mo>+</mo><mn>1</mn><mo>=</mo><mn>2</mn></math>
.


Multiline display math that might look like an unordered list
.
$$$
  1

+ 1
+ 1

= 3
$$$
.
<math display="block"><mn>1</mn><mo>+</mo><mn>1</mn><mo>+</mo><mn>1</mn><mo>=</mo><mn>3</mn></math>
.


Text can immediately follow inline math
.
$$n$$-th order
.
<p><math><mi>n</mi></math>-th order</p>
.


Display math self-closes at the end of document
.
$$$
1+1 = 2
.
<math display="block"><mrow><mn>1</mn><mo>+</mo><mn>1</mn></mrow><mo>=</mo><mn>2</mn></math>
.


Display and inline math can appear in lists
.
* $$1+1 = 2$$
* $$$
  1+1 = 2
  $$$
.
<ul>
<li><math><mrow><mn>1</mn><mo>+</mo><mn>1</mn></mrow><mo>=</mo><mn>2</mn></math></li>
<li>
<math display="block"><mrow><mn>1</mn><mo>+</mo><mn>1</mn></mrow><mo>=</mo><mn>2</mn></math>
</li>
</ul>
.


Display math can be written in one line
.
$$$1+1 = 2$$$
.
<math display="block"><mrow><mn>1</mn><mo>+</mo><mn>1</mn></mrow><mo>=</mo><mn>2</mn></math>
.


Or on multiple lines with expression starting and ending on delimited lines
.
$$$[
[1, 2]
[3, 4]
]$$$
.
<math display="block"><mfenced open="[" close="]"><mtable><mtr></mtr><mtr><mtd><mn>1</mn></mtd><mtd><mn>2</mn></mtd></mtr><mtr><mtd><mn>3</mn></mtd><mtd><mn>4</mn></mtd></mtr><mtr></mtr></mtable></mfenced></math>
.


Escaped delimiters should not render math
.
Foo \$$1$$ bar
\$\$$
1
\$\$$
.
<p>Foo $$1$$ bar
$$$
1
$$$</p>
