Writing technical content in Markdown

One of the challenges a modern day scientist, student, teacher or any other enthusiastic problem solver faces is how to efficiently write and document scientific and technical information in the digital form. However, one’s typical tool kit usually looks quite heavy and may include an editor, converter, typesetting system and other supplementing tools at the least. All of these needs to be installed, configured, learned and adapted to suit individual needs, which inevitably impairs productivity and adds unnecessary burden to the whole process.

The math talk is easy here! You can post complex math equations in a simple and fast way. No need to take screenshots to post math, simply put KaTex math notation between the code blocks ``` to display formulas, equations, symbols, and functions.

Writing math in Markdown

Publishing math texts and sharing them on the web is usually a big challenge, especially when it comes to lengthy and complex formulas and equations.

However, this could be done with no hassle on P4, and is very easy if you are already familiar with KaTex commands. You can post any expression inline (within the text) or in block (as a separate line), which is handy for big equations.

KaTex — the fastest math typesetting library for the web.

Block math

To add a math element in block, use either math or katex command code, like this:

Inline math

To add a math element in text, simply surround it by double dollar marks $$\sqrt{x}$$, and it will automatically convert it to look like this: .
