Testing maths handling, both inline ([math]\partial y/\partial x[/math]) and displayed:

[math] x = {-b \pm \sqrt{b^2 -4ac}\over 2a}[/math]

All seems to work nicely! Of course, things get more complicated when there is lots of text so that the embedded inline math (again, [math]\partial y\partial z/\partial x[/math]) is fully within the text of the paragraph and therefore will interfere with the interline spacing.

Problems with bold subscripts:

[math]\bold{d_h} = \sqrt{2x +y^2}[/math]
