If you are creating content with formulas, you can easily add these formulas to your Cerego content using the following flow:
1. Have your formula on hand in Latex form and navigate to this site: latex2png
2. Insert your formula into the Latex field and hit convert to make it an image (.png file)
3. Save the image
4. Now that you have the image, you can upload this anywhere in the Cerego authoring tool that allows images. For example, let's make a Flashcard – the front of the card will be the image of the formula, and the back will be text "Standard Deviation Formula"
Voila! You now have math formulas in your Cerego content!
