How to Use Inline Equations in Notion – A Complete Guide


Notion is a great tool for taking notes and generally being a versatile productivity tool. But what is you need to write out equations and other math content in Notion? Notion has you covered with inline math support.

So how do you create an inline equation in Notion? Enclosed below are the steps required to write a math equation in Notion:

  1. Open Notion to the page you want to create your inline equation
  2. Type $$ to tell Notion you want to write inline math
  3. Write out your equation using in katex format
  4. End your inline math equation with $$ to tell Notion that the inline equation is complete

Notion uses the Katex library to write and render math inside of Notion. You can find a list of Katex functions here.

Before we get started with the tutorial, if you are looking to learn more about apps like Notion, Todoist, Evernote, Google Docs, or just how to be more productive (like Keep Productive’s awesome Notion course), you should really check out SkillShare.

Let’s get started with the tutorial 😀.

Writing Inline Math in Notion

Open up Notion to the page where you want to write your math equation.

The way you indicate to Notion that you want to write out a math equation is by using $$. Click in the body of your Notion page and type $$.

Next, you need to write out your equation using katex format. Let’s write out a simple equation that has squares in it. The way you indicate a square in katex is to use the ^ symbol. To test it, type out the equation in the above screenshot.

Next you need to type $$ again at the end of the equation to tell Notion that the equation is complete. As soon as you finish typing $$, you should notice the equation being rendered as shown below:

As you can see, Notion realizes what the equation is and renders it properly. Next, let’s look at how to type out common math symbols and equations in Notion. Let’s start with fractions.

Writing Fractions in Notion

Let’s say you are writing out a formula or even a recipe that requires a fraction, like 1/2. The way you write a fraction in Notion is:

Once you finish typing the $$ at the end of the equation, you should see 1/2 rendered like the screenshot below:

Once again, Notion understands that you want to render a fraction and does so appropriately.

You can also write more complex equations as well like 2 over b +1. The way you would write this in Notion is:

This look complicated but let’s break it down piece-by-piece to understand what is going on in this equation:

The opening { indicates a complex equation to Notion. Next comes the first variable, which is “a” then a space. The above indicates that a is the “top” value of the fraction. The {1pt} tells Notion how thick to make the fraction line. The b+1 is the bottom of the fraction.

As you can see, Notion recognizes this schema and renders the equation correctly.

Writing Square and Cube Roots in Notion

Writing square roots in Notion is pretty straight-forward. If, for example, you wanted to write square root of 9, you would type:

You are not limited to square roots. For example, you could do a cube root like the cube root of 27, which you would write out like this:

We use the same sqrt function but we add the [3] that tells Notion that we want the cube root symbol.

Notion renders the equation successfully.

Writing Math Symbols in Notion

You can also write math symbols in Notion. Enclosed below is a table contains some of the symbols you can write in Notion:

NameSymbol
AlphaA
alphaα
BetaB
betaβ
GammaΓ
gammaγ
DeltaΔ
deltaδ
EpsilonE
epsilonϵ
ZetaZ
zetaζ
LambdaΛ
lambdaλ
OmegaΩ
omegaω
piπ
