You bet, it does. Quosera supports mathematics using MathML and TeX so if you are familiar with TeX or MathML syntax then you can easily write mathematical equations.

As as example, below mentioned TeX code 

x = {-b \pm \sqrt{b^2-4ac} \over 2a}

will look like this

\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)
