When you are familiar with LaTeX, it may be more time-efficient or easier to copy the LaTeX code of an equation or type it yourself. Below, a few basic LaTeX codes are written. Also, it may come in useful to use an external LaTeX editor, such as

*Visual Math Editor**in which you can get familiarised with LaTeX equations (even more). These editors have more possibilities than the equation editor implemented in the Ans platform.*- Go to a question, content or criteria box and start with two dollar signs if you want the equation to be in the text ($$). If the equation should be on a separate line, use three dollar signs ($$$).

(Do not use the LaTeX functionality*\begin{equation} ... \end{equation}*, which is used to write an equation in LaTeX. This does not work in the Ans platform.) - Type or copy the LaTeX code. A few basic operations are explained below. For more of these operations, go to this link which lists all functions supported by LaTeX in the math mode (math mode is in between the dollar signs), or use the
*Visual Math Editor***Plus**or**minus**: z = x + y - 1**Multiplying**: x*y, x \cdot y**Superscript**: x^{2}**Subscript**: x_{2}**Fraction**: \frac{1}{x}**Root**: \sqrt{x}**Trigonometric functions**: \sin{x}, \cos{x}, \tan{x}**Greek letters**: \pi, \alpha, \beta, \delta*etc.* - If the equation is finished, end with the same amount of dollar signs as you started with, so $$ or $$$.
- Click save and look at the render if the equation looks like you desire.
