Headers

Use two hash signs for the primary header

Secondary header

Create subheaders by using an additional hash sign

Tertiary header

You can keep going as deep as you want, but try to limit it to this level.

Basic formatting

Bold

Bold text is annotated using two stars on each side.

We typically use bold text to emphasize key terms.

Italic

Italic text is annotated using one star or underline on each side.

We typically use italic text when quoting passages or answer choices inline in a sentence.

Underline

Underlined text is annotated using the u tag on both sides.

We typically use underlined text to emphasize word stems like prefix or, or for fill-in-the-blank question choices in their passage.

Strikethrough

~~Strikethrough text~~ is surrounded by two squiggles.

Lists

Bulleted lists are annotated with stars or dashes. Either is ok, but don’t mix and match in the same list. You can create a sub list item by indenting four spaces.

Unordered lists

Unordered list using stars

Whitespace

Markdown is very picky about the use of whitespace.

For creating whitespace, you can use:   or $\;$

In the below examples, these options are used in between the words One and Two.

One Two

If you find that things are not displaying how you expect/want, talk with Justin!

Using hacks to display things will eventually break - it’s better if we understand the root cause and adjust our primary layout.

To create a new paragraph, you must have a completely empty line separating it. See how this sentence is part of the same paragraph although it’s on the next line?

You need to have a fully blank line between. Or, end the line with a backslash.
A backslash creates an inline break, where you get a newline, but it’s part of the same paragraph. This is useful when you have multi-line definitions, list items, etc.

Tables

Tables can be added to display data. Since the course is often used on mobile, prefer vertical tall and skinny tables over horizontal short and fat tables.

Left aligned	Centered	Right aligned
1111	2222	3333
1	2	3

The row after the headers is the alignment key.

Quotes

Pull quotes are used for quotes, quoted passages, and questions.

Single line quote

If you need multiple lines, start each with the symbol.

How many cats are in the bag?

A. Two
B. One
C. None, the cat is out of the bag

Note how a backslash or empty quoted line is needed to create newline breaks.

Callout content

Sidenotes are like callouts, but usually used for information on a specific subtopic.

Sidenote

Sidenote content

Keypoints are for summarizing sections, chapters, and ideas. Use the block format for passage quotes or other long-form external content blocks.

In my younger and more vulnerable years my father gave me some advice that I’ve been turning over in my mind ever since. “Whenever you feel like criticizing any one,” he told me, "just remember that all the people in this world haven’t had the advantages that you’ve had.”

Use the markdownCode format for monospace text like code or terminal output.

The comment callout is good for internal notes (hidden below, viewable in the editor).

Math

Inline equations

Inline equations are used by surrounding the equation with dollar signs. Do your best to include equations in the middle of a sentence like $a = b + c$ , rather than at the start or end.

Block equations

In general, prefer block equations instead of inline equations since they’re easier to read.

$a = m x + b$

You can use equations in quotes or in other blocks.

Simplify the following expression:

$\frac{30 x - 24}{3}$

It’s possible to include text in a math block.

$number of cats = 8$

Aligned equations

There are two primary ways to align equations.

For proper equations with equal signs, use the aligned tag. The ampersand & symbol marks an alignment point. Note how each line ends with two backslashes.

$a a - b = b + c = c$

You can have multiple alignment points, but each line needs to have the same quantity.

$a a - b = b + c = c = 4 = 4$

For definitional equations, only include the defined term in the first line.

$a = 1 + 2 * 3 - 4 = 1 + 6 - 4 = 7 - 4 = 3$

Prefer proper equations with equal signs, since they’re easier to read. But if you have a group, you can use the gather* tag.

$1 + 2 * 3 - 4 1 + 6 - 4 7 - 4 3$

Dollar sign

If you want to use inline equations with amounts of money, do the following:

He spent $$80$ on the food.

Solve for $x$ . $$10 + $ x = $12$

Math symbols

Fractions

Fractions can be written vertically or horizontally, depending on the use.

$(15 x - 9) /3 = \frac{15 x - 9}{4}$

Square roots

$27$

You can also write them as $n$ -roots.

$n 27$

Exponents

Use the ^ to make exponents.

$4^{5}$

You can also do negatives and numbers 10 or over using curly brackets.

$1 0^{10}$

$1 0^{- 1}$

You can also combine exponents and fractions.

$\frac{( c ^{- 2} ) ( d ^{3} )}{( c ^{4} ) ( d ^{- 1} )}$

Left aligned	Centered	Right aligned
1111	2222	3333
1	2	3

The row after the headers is the alignment key.

Quotes

Pull quotes are used for quotes, quoted passages, and questions.

Single line quote

If you need multiple lines, start each with the symbol.

How many cats are in the bag?

A. Two
B. One
C. None, the cat is out of the bag

Note how a backslash or empty quoted line is needed to create newline breaks.

Custom components

Definitions

If you have terms to define, use a definitions box.

Definitions

First term: First term description
You can have multiple lines
Second term: Second term description

Callouts / sidenotes / keypoints

Callouts are like little warning banners to emphasize key info.

Callout content

Sidenotes are like callouts, but usually used for information on a specific subtopic.

Sidenote

This is the title

Sidenote content

Keypoints are for summarizing sections, chapters, and ideas. Use the {`block`} format for passage quotes or other long-form external content blocks.

Use the {`markdownCode`} format for monospace text like code or terminal output.

The comment callout is good for internal notes (hidden below, viewable in the editor).

This text is visible in the editor but HIDDEN in the learner view.

It is HIDDEN, not REMOVED. A tech-savvy user will still be able to view it.

It will just not be displayed on the normal page.

Do not put anything sensitive in comments.

Math

Inline equations

Inline equations are used by surrounding the equation with dollar signs. Do your best to include equations in the middle of a sentence like $a = b + c$ , rather than at the start or end.

Block equations

In general, prefer block equations instead of inline equations since they’re easier to read.

$a = m x + b$

You can use equations in quotes or in other blocks.

Simplify the following expression:

$\frac{30 x - 24}{3}$

It’s possible to include text in a math block.

$number of cats = 8$

Aligned equations

There are two primary ways to align equations.

For proper equations with equal signs, use the {`aligned`} tag. The ampersand & symbol marks an alignment point. Note how each line ends with two backslashes.

$a a - b = b + c = c$

You can have multiple alignment points, but each line needs to have the same quantity.

$a a - b = b + c = c = 4 = 4$

For definitional equations, only include the defined term in the first line.

$a = 1 + 2 * 3 - 4 = 1 + 6 - 4 = 7 - 4 = 3$

Prefer proper equations with equal signs, since they’re easier to read. But if you have a group, you can use the {`gather*`} tag.

$1 + 2 * 3 - 4 1 + 6 - 4 7 - 4 3$

Dollar sign

If you want to use inline equations with amounts of money, do the following:

He spent $$80$ on the food.

Solve for $x$ . $$10 + $ x = $12$

Math symbols

Fractions

Fractions can be written vertically or horizontally, depending on the use.

$(15 x - 9) /3 = \frac{15 x - 9}{4}$

Square roots

$27$

You can also write them as $n$ -roots.

$n 27$

Exponents

Use the ^ to make exponents.

$4^{5}$

You can also do negatives and numbers 10 or over using curly brackets.

$1 0^{10}$

$1 0^{- 1}$

You can also combine exponents and fractions.

$\frac{( c ^{- 2} ) ( d ^{3} )}{( c ^{4} ) ( d ^{- 1} )}$

Plus-minus

$\pm$

Less than and greater than

$<$

$>$

Less than or equal to and greater than or equal to

$\leq$

$\geq$

$≰$

$≱$

Division and multiplication signs

$\div$

$\times$

Percent sign

The percent sign can sometimes cause issues with formatting.

Percent sign is not showing up: $40$
Percent sign not the same font: $40$ %

Use a slash to fix the issue: $40%$

Geometry and other math-related symbols

You can make symbols for triangles.

$◃$

$▹$

$△$

$▽$

$△$

You can make symbols for angles.

$∠$

$∡$

$∢$

You can make symbols for different lines.

$\overline{A B}$

$\underline{A B}$

$A B$

$\to$

$\leftarrow$

$\leftrightarrow$

Audio

The system will create narrated audio automatically based on your markdown content. If you need fine-grained control over the audio, or you have a situation that benefits from customized audio, you can use the {`::: audio :::`} block. Three stars {`***`} are used as a separator; the text above the stars will be read aloud, and anything below will be skipped.

{`::: audio 
This text will be narrated instead of the table below.
