Design Science MathPlayer is a free plugin for browsers, including InternetExplorer, that allow rendering of math notation using MathMl.
See http://www.dessci.com/en/products/mathplayer/
Server-side programs could output content as MathMl, ScalableVectorGraphics, and/or VirtualRealityModelingLanguage to make formulas, 2D and/or 3D figures as seen in most mathematical texts easily viewable (even interactive) in client browsers over the internet using such plug-ins. This could reduce the perception that MathIsHard.
Example MathMl ("presentation" elements):
<math xmlns="http://www.w3.org/1998/Math/MathML">
<msup> <mi>n</mi> <mrow> <mi>p</mi> <mo>-</mo> <mn>1</mn> </mrow> </msup> <mspace width=".2em"/> <mo>¡Ô</mo> <mspace width=".2em"/> <mn>1</mn> <mspace width=".2em"/> <mo>(</mo> <mi>mod</mi> <mspace width=".2em"/> <mi>p</mi> <mo>)</mo></math>
