With the 2016 rebuild of our question editor we've incorporated a new HTML editor that supports TeX (newest versions are now called LaTeX).

What is TeX and/or LaTeX?

TeX is a system for creating a simple construction of mathematical formulae, while looking professional when printed. In our editor is a math symbol button that opens to the TeX editor, allowing you to type printed text that is rendered into formulae.

Mathematics has many symbols! One of the most difficult aspects of learning LaTeX is remembering how to produce symbols. To get you started here is a wiki page on how to use TeX to create your own scientific and mathematical formulae. 

Can you imagine creating the equations even more powerful than the quadratic equation with simple text.  Now you can!
