​
What is this feature?

The Math Inputs feature allows you to insert properly formatted mathematical equations and notation directly into your Playlab conversations. Whether you’re working with algebraic expressions, calculus problems, trigonometric functions, or matrices, you can now input complex mathematical notation using a convenient equation editor with just a few clicks. Think of it like having a built-in mathematical keyboard at your fingertips. Instead of trying to type out equations using plain text or worrying about how to represent mathematical symbols, you can use the interface to build equations with proper formatting and notation that Playlab can understand and work with. Behind the scenes, the editor converts your visual input into LaTeX mathematical notation, which is then rendered using KaTeX for high quality display.
Math inputs require the equation editor interface to ensure proper formatting and interpretation of mathematical notation.

​
What is the Rationale for this feature?

Currently, entering mathematical notation in plain text can be cumbersome and prone to errors. Trying to communicate complex equations using only keyboard characters often results in ambiguous or unclear expressions that are difficult for both AI and humans to interpret correctly. This creates friction when working on mathematical problems, teaching math concepts, or generating math-related educational content. The Math Inputs feature is a step towards eliminating these challenges by providing a dedicated equation editor that ensures mathematical expressions are properly formatted and unambiguous. The visual editor converts your button clicks and selections into LaTeX notation (the gold standard for mathematical typesetting), and then displays the result using KaTeX, a fast rendering library that produces crisp, professional mathematical notation. This two-step process makes it easier to work with mathematical content in Playlab while maintaining precision and clarity in your mathematical communication.

How to Use Math Inputs

1

Locate the Calculator Icon

Look for the calculator icon in the chat input bar at the bottom of your Playlab interface.
2

Open the Equation Editor

Click the calculator icon to open the “Insert Equation” dialog box.
3

Build Your Equation

Use the equation editor interface to construct your mathematical expression:
  • Click number buttons (0-9) to enter digits
  • Use operation buttons (+, -, ×, ÷, =) for basic operations
  • Select from function categories: Functions, Algebra, Calculus, Matrices
  • Click specific functions like sin, cos, tan, log, ln, exp, etc.
4

Preview Your Equation

The Preview section shows how your equation will appear in properly formatted mathematical notation.
5

Insert the Equation

Once you’re satisfied with your equation, click the Insert button to add it to your chat message.
6

Send Your Message

Complete your message with any additional text or context, then send it to your Playlab app.

​
Best Practices

The equation editor organizes functions into categories for easy access:
  • Functions: Basic trigonometric and logarithmic functions (sin, cos, tan, sec, arcsin, arctan, log, ln)
  • Algebra: Algebraic operations and expressions (cos, cot, sinh, cosh)
  • Calculus: Calculus-specific notation (tan, arcsin, cosh, tanh)
  • Matrices: Matrix operations and absolute value (csc, arccos, tanh, |x|)
Select the appropriate category to quickly find the functions you need.
Always check the Preview section before inserting your equation. This ensures that your mathematical notation appears exactly as you intended and helps catch any formatting issues before you send your message.
While the math input creates properly formatted equations, remember to include explanatory text in your message to provide context. For example: “Solve this equation for x:” followed by your inserted equation, or “What is the derivative of” followed by your function notation.
For complex equations, start by entering the basic structure and then add more sophisticated elements. The equation editor makes it easy to build up complicated expressions step by step rather than trying to enter everything at once.
Math inputs are particularly powerful for:
  • Creating practice problems with proper notation
  • Demonstrating step-by-step solutions
  • Generating worksheets with correctly formatted equations
  • Explaining mathematical concepts with precise notation

​
Known Issues

As this feature is currently in beta, there are a few known limitations to be aware of:
Issue: Do not try to insert more than one equation at a time in the same message. While multiple equations may look correct in the text input field, they will not display with proper formatting in the chat.Workaround: Insert a new line using Shift + Enter after each equation before inserting the next one. This will ensure each equation renders correctly in the chat display.Example:
  • Insert first equation
  • Press Shift + Enter to create a new line
  • Insert second equation
Issue: If you delete characters using your keyboard (backspace or delete keys) while editing an equation in the text input field, the equation may not parse correctly and will display an error.Workaround: If you need to modify an equation after inserting it:
  • Clear the entire equation from the text input
  • Click the calculator icon to open the equation editor again
  • Rebuild the equation from scratch using the editor interface
Avoid using keyboard deletion on inserted equations to prevent parsing errors.

Frequently Asked Questions

The math input editor uses a two-step process to convert your visual equation building into beautifully formatted mathematical notation:
  1. LaTeX Conversion: As you click buttons and build your equation in the editor, your input is automatically converted into LaTeX markup. LaTeX is the standard mathematical typesetting language used in academic and scientific publishing. For example, when you click “sin” and then “x”, the editor generates the LaTeX code \sin(x).
  2. KaTeX Rendering: Once the LaTeX notation is generated, it’s rendered using KaTeX, a fast and lightweight mathematical rendering library. KaTeX takes the LaTeX code and transforms it into crisp, professional-quality mathematical notation that displays perfectly in your browser.
This means you get the precision of LaTeX and the beautiful rendering of KaTeX without needing to write any code yourself. The entire process happens automatically behind the scenes.
The math input feature supports:
  • Basic arithmetic operations (+, -, ×, ÷)
  • Exponents and powers (x², y³)
  • Trigonometric functions (sin, cos, tan, sec, csc, cot)
  • Inverse trigonometric functions (arcsin, arccos, arctan)
  • Hyperbolic functions (sinh, cosh, tanh)
  • Logarithms (log, ln)
  • Exponential functions (exp)
  • Absolute value (|x|)
  • Matrix notation
  • Algebraic expressions and equations
Currently, once an equation is inserted into your message, you would need to use the equation editor again to create a corrected version. We recommend using the preview feature to verify your equation before inserting it.
No, the math input feature works entirely within your web browser using the built-in equation editor. You don’t need any special mathematical keyboards, LaTeX knowledge, or additional software installations.
No! That’s the beauty of the math input editor. While the feature uses LaTeX notation internally and KaTeX for rendering, you never need to write or understand LaTeX code. The visual equation editor handles all the conversion and formatting for you automatically. Simply click the buttons and build your equations visually, and the system takes care of:
  • Converting your input into proper LaTeX notation
  • Rendering the LaTeX using KaTeX for beautiful display
  • Ensuring your equations are formatted correctly
You get all the benefits of professional mathematical typesetting without any of the technical complexity.
Yes, the math input feature is available on mobile devices through the Playlab mobile app. The equation editor interface is optimized for touch input on smaller screens.
Yes, mathematical notation entered through the math input feature works across all Playlab apps. Any app that can process mathematical content will correctly interpret the equations you insert.
The equation editor is designed for building equations from scratch using its interface. If you have equations in other formats (like LaTeX or plain text), you’ll need to recreate them using the editor buttons and functions.
While there’s no strict limit on equation complexity, extremely long or deeply nested expressions may be challenging to build in a single equation input. For very complex mathematical content, consider breaking it into multiple equations or steps.
