How to Add Inline Equations and Formulas in Notion?

Notion’s support for inline equations and formulas opens up new possibilities for math, science, and technical documentation. With the help of LaTeX—a typesetting language for mathematical expressions—Notion users can create complex equations, symbols, and even formatted mathematical functions. Whether you’re managing budgets, documenting scientific formulas, or creating study notes, inline equations make it easy to add professional, readable formulas directly to your Notion pages.

This guide will walk you through the basics of adding inline equations, provide examples for common use cases, and cover best practices for formatting and customization.

Adding an Inline Equation in Notion

Notion makes it easy to add inline equations, which appear within a line of text, making them perfect for notes or explanations. Inline equations work similarly to other text, allowing you to place formulas and expressions seamlessly alongside written content.

Steps to add an inline equation:

1. Place your cursor where you want the inline equation within a text block.
2. Type $ (single dollar sign) to start an inline equation.
3. Enter your formula or mathematical expression using LaTeX syntax. For instance, typing x^2 + y^2 = z^2 will create the formula x2+y2=z2x^2 + y^2 = z^2×2+y2=z2.
4. Close the expression with another $ to complete it.

For example, if you type $E = mc^2$ within a text block, it will display the equation E=mc2E = mc^2E=mc2 inline, allowing you to explain concepts or calculations without breaking the text flow.

Writing Basic Mathematical Symbols and Operations

In LaTeX syntax, simple operations like addition, subtraction, multiplication, and division can be represented directly. Let’s look at some basic examples:

• Addition and Subtraction: Simply use + and -.
  • Example: Typing $a + b - c$ will display as a+b−ca + b – ca+b−c.
• Multiplication: Use an asterisk (*) or \cdot for a centered dot.
  • Example: $a * b$ displays as a×ba \times ba×b, while $a \cdot b$ displays as a⋅ba \cdot ba⋅b.
• Division: Use / or \frac{numerator}{denominator} for fractions.
  • Example: $a / b$ displays as a÷ba \div ba÷b, while $\frac{a}{b}$ displays as ab\frac{a}{b}ba​.

Adding basic symbols to inline equations makes it easy to represent simple math and calculations.

Using Exponents, Subscripts, and Fractions

Inline equations also support formatting for exponents, subscripts, and fractions, making it possible to add scientific formulas, mathematical proofs, and other complex expressions.

• Exponents: Use the caret symbol (^) to indicate exponents.
  • Example: $x^2$ displays as x2x^2×2.
  • Example with text in exponent: $x^{power}$ displays as xpowerx^{power}xpower.
• Subscripts: Use an underscore (_) for subscripts.
  • Example: $x_1$ displays as x1x_1x1​.
• Fractions: Use \frac{numerator}{denominator} to create fractions.
  • Example: $\frac{a}{b}$ displays as ab\frac{a}{b}ba​.
  • For more complex fractions, wrap terms in curly braces: $\frac{a+b}{c+d}$ displays as a+bc+d\frac{a+b}{c+d}c+da+b​.

Using exponents, subscripts, and fractions allows you to create professional-looking mathematical expressions perfect for academic, financial, and technical content.

Adding Greek Symbols and Special Characters

LaTeX in Notion also supports Greek symbols and various special characters commonly used in scientific fields. Simply enter the LaTeX name of the symbol, preceded by a backslash.

• Greek Letters: Use backslashes followed by the letter name.
  • Example: $\alpha + \beta = \gamma$ displays as α+β=γ\alpha + \beta = \gammaα+β=γ.
• Special Characters:
  • Integral: $\int_a^b x \,dx$ displays as ∫abx dx\int_a^b x \,dx∫ab​xdx.
  • Sum: $\sum_{n=1}^{\infty} \frac{1}{n^2}$ displays as ∑n=1∞1n2\sum_{n=1}^{\infty} \frac{1}{n^2}∑n=1∞​n21​.

Common symbols and their syntax:

• Pi: $\pi$ → π\piπ
• Infinity: $\infty$ → ∞\infty∞
• Theta: $\theta$ → θ\thetaθ
• Delta: $\Delta$ → Δ\DeltaΔ

Adding Greek letters and special characters allows you to create visually rich, field-specific equations that enhance the clarity of your content.

Using Inline Formulas for Calculations

Inline formulas are great for calculations and logical expressions that require dynamic output. Although Notion’s LaTeX does not perform calculations, you can create formulas for calculated properties in databases, making Notion a functional space for basic computational tasks.

Steps to use calculated properties in databases:

1. Add a new property to your database and set it as Formula.
2. Enter your calculation using Notion’s formula syntax, such as prop("Price") * prop("Quantity").
3. The result will be displayed dynamically, and the calculations will be recalculated as you update database entries.

For example, you could create a “Total Cost” column in an inventory database where each entry multiplies “Price” by “Quantity,” allowing for automatic calculations without manual entry.

Practical Examples of Inline Equations

Let’s look at a few more examples that demonstrate how inline equations can be used across different contexts.

1. Physics Equations:
   • Formula: $F = ma$ displays as F=maF = maF=ma.
   • Description: This is Newton’s second law, where force equals mass times acceleration.
2. Statistics Equations:
   • Formula: $E(X) = \sum_{i=1}^n x_i p(x_i)$ displays as E(X)=∑i=1nxip(xi)E(X) = \sum_{i=1}^n x_i p(x_i)E(X)=∑i=1n​xi​p(xi​).
   • Description: This is the expected value of a discrete random variable.
3. Financial Formulas:
   • Formula: $\text{ROI} = \frac{\text{Gain} - \text{Cost}}{\text{Cost}} \times 100$ displays as ROI=Gain−CostCost×100\text{ROI} = \frac{\text{Gain} – \text{Cost}}{\text{Cost}} \times 100ROI=CostGain−Cost​×100.
   • Description: This formula calculates the return on investment as a percentage.
4. Trigonometry:
   • Formula: $sin(\theta) = \frac{opposite}{hypotenuse}$ displays as sin⁡(θ)=oppositehypotenuse\sin(\theta) = \frac{opposite}{hypotenuse}sin(θ)=hypotenuseopposite​.
   • Description: This formula represents the sine function in trigonometry.

These examples show how versatile inline equations can be, allowing you to add depth and clarity to your documentation, study materials, and project notes.

Best Practices for Using Inline Equations in Notion

To make the most of inline equations in Notion, follow these best practices to ensure readability and organization.

• Use Consistent Formatting: Consistently use the same format for variables and symbols (e.g., italicize variables, use regular font for constants).
• Label Equations Clearly: When using inline equations, include a brief label or description for clarity, especially in technical content.
• Test Complex Formulas in a Sandbox: If you’re working with complex LaTeX, test your formulas on a blank page to avoid errors.
• Break Down Complicated Equations: For readability, split complex formulas across multiple inline blocks or add explanations between steps.
