## Math You can post complex math equations in a simple and fast way using Markdown and KaTex. No need to take screenshots to write about math, use [KaTex](https://khan.github.io/KaTeX/) syntax to display formulas, equations, symbols, and functions unline and in block as described bellow. It will serve you well for mathematical blogs and notes taking. ### Inline math To add a math element in text, surround it by double dollar marks `$$\sqrt{x}$$`, and it will automatically convert it to look like this: $$\sqrt{x}$$. ### Block math To add a math element in block, use either ```math``` or ```katex``` command code between block code fences ` ``` `, like this: ```katex \cfrac{a}{1 + \cfrac{1}{b}} ``` ```katex \cfrac{a}{1 + \cfrac{1}{b}} ``` Check out [\~math](https://onp4.com/@p4/~math) stream for more.
