To test a MathML block and enter a formula, for example: \[x = {-b \pm \sqrt{b^2-4ac} \over 2a}\].

To test using math formulas inline, type an formula into a block of text, select it and hit the ‚M‘ icon in the control bar. For example: \( \cos(θ+φ)=\cos(θ)\cos(φ)−\sin(θ)\sin(φ) \)Note: if you are copying and pasting formulas into the rich text editor, switching to HTML/code editor mode is less likely to reformat your pasted formula.
