How to create a line break?
To create a linebreak:
In theory pages, press shift+enter in the editor.
In exercises, press enter.
Inside latex equations, you can also use line breaks to format the source, but not paragraphs. It's best to always use line breaks when working inside a latex equation.
In the resulting HTML (press the source code button to see the HTML), you will see that the editor inserts linebreak (br) tags.
Too much white space after a MathJax display environment
If you create an exercise, and include a display MathJax environment, you may have noticed that you get too much white space. For example:
Note that if we multiple
\[ \frac{x}{2}=2 \]
by two, we get
\[ x=4 \]
This will look like this for the student (note the extra break after the equation):
You can solve this by pressing shift+enter (instead of enter) after a display equation. In the editor this will look like there is more space, but the student will not get the extra line break.
