# Math Equation Support

If you add TeX or ASCII Math strings into the assignment/assessment instructions box, or into assessment questions, answers, or feedback, they will be rendered as math equations when saved.

Most math textbooks include the text needed to create the correct math symbols; eBackpack can now support those symbols on assignments & assessments on the web as well as assessments on iOS. Mobile support for equations in assignment instructions will be coming soon.

For TeX support, surround text with $$• Example equation:$${x = \frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}}$$•$${\frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x).}

For ASCII Math support, surround text with 

• Example equation: x = (-b +- sqrt(b^2 - 4ac)) / (2a)
