LaTeX vs. AsciiMath in Markdown: Which is Better for Technical Writing?
When writing technical documents, academic papers, or engineering notes, you inevitably need to format mathematical equations. The two leading standards for writing math on the web are LaTeX and AsciiMath. Here is a deep dive into how they compare, and which one you should choose for your workflow.
The Heavyweight: What is LaTeX?
LaTeX is the undisputed industry standard for academic, scientific, and mathematical typesetting. Originally developed in the 1980s, it is incredibly powerful and expressive, capable of rendering almost any mathematical concept, matrix, or symbol imaginable.
LaTeX Pros & Cons
- Pros: Universal standard (accepted by all journals), infinitely extensible, massive community, beautiful rendering engines (like KaTeX and MathJax).
- Cons: Extremely steep learning curve, verbose syntax heavily reliant on backslashes and curly braces, harder to read in raw Markdown form.
Example (Quadratic Formula):\frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
The Challenger: What is AsciiMath?
AsciiMath is a modern, client-side mathematical markup language designed specifically to be easy to write and highly readable before it is rendered. It looks much closer to how you would naturally type math into a standard calculator or a programming language.
AsciiMath Pros & Cons
- Pros: Very easy to learn, highly readable source code, incredibly fast to type during rapid note-taking.
- Cons: Less extensible than LaTeX, not universally supported across all markdown platforms, lacks some advanced formatting options.
Example (Quadratic Formula):(-b +- sqrt(b^2 - 4ac)) / (2a)
Head-to-Head Syntax Comparison
Let's look at how common mathematical expressions are written in both languages:
| Expression | LaTeX | AsciiMath |
|---|---|---|
| Fractions | \frac{x}{y} | x / y |
| Square Roots | \sqrt{x^2 + 1} | sqrt(x^2 + 1) |
| Integrals | \int_{0}^{\infty} e^{-x} dx | int_0^oo e^-x dx |
| Greek Letters | \alpha, \beta, \theta | alpha, beta, theta |
Which Should You Use?
The choice depends entirely on your context:
- Choose LaTeX if: You are writing a formal academic paper destined for a university journal, building complex matrices, or working in an environment where strict standardisation is required.
- Choose AsciiMath if: You are taking rapid class notes, writing internal engineering documentation, solving homework problems, or building a personal knowledge base where speed and raw-text readability are paramount.
Why Not Both? The xyzEditor Approach
At xyzEditor, we realised that users shouldn't be forced into a rigid silo. Technical writing often requires a mix: rapid AsciiMath for simple inline equations, and robust LaTeX for complex display blocks.
Our local-first editor natively supports both syntaxes simultaneously within the same Markdown document, rendering them in real-time.
How to format math in xyzEditor:
- 1For LaTeX: Wrap your math in
$$for display blocks or$for inline math. - 2For AsciiMath: Simply wrap your math in backticks (
`) and enable the Code Override toggle. This converts all inline code blocks directly into perfectly rendered equations, allowing incredibly fast typing without ever reaching for the Shift key!
