I chose it over MathJax because it performs substantially faster. The equation environment is used to typeset one formula. If you are new to using the LaTeX math mode see How to write LaTeX.
With this macro it is really easy to integrate formulas in confluence pages.
It also defines the TeX delimiters for displayed equations but it does not define as in-line math delimiters. Convert multiple equations at the same time using any function supported by LaTeX. By default the tex2jax preprocessor defines the LaTeX math delimiters which are for in-line math and for displayed equations. Add equations units and more.
