How to push MathML forward?

• Use it!
• Always include MathML
• Even when using fallback
• use annotations for alternative formats
• Understand the pitfalls
• Browser support
• ereading systems
• Overcome the pitfalls
• polyfills
• fallbacks

Easy example

$$\begin{array}{ccc}{\int }_1^x\frac{\mathit{d}t}{t}& & \left(\genfrac{}{}{0ex}{}{p}{2}\right)x^2{y}^{p-2}-\frac{1}{1-x}\frac{1}{1-x^2}\\ & & \\ x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}& & {\left(\underset{k=1}{\overset{n}{\sum <!--\; \sum \; -->}}{a}_k{b}_k\right)}^2\le <!--\; \le \; -->\left(\underset{k=1}{\overset{n}{\sum <!--\; \sum \; -->}}{a}_k^2\right)\left(\underset{k=1}{\overset{n}{\sum <!--\; \sum \; -->}}{b}_k^2\right)\end{array}$$

Hard example

$\begin{array}{ccc}k\cdot <!--\; \cdot \; -->x=\stackrel{\stackrel{k\text{times}}{⏞}}{x+...+x}& \leftarrow & {\displaystyle \{\begin{array}{rcl}\nabla \text{}\times \underset{}{\overset{\leftharpoonup }{B}}-\frac{1}{c}\frac{\partial \text{}\underset{}{\overset{\leftharpoonup }{E}}}{\partial \text{}t}& =& \frac{4\pi }{c}\underset{}{\overset{\leftharpoonup }{j}}\\ \nabla \text{}·\underset{}{\overset{\leftharpoonup }{E}}& =& 4\pi \rho \\ \nabla \text{}\times \underset{}{\overset{\leftharpoonup }{E}}+\frac{1}{c}\frac{\partial \text{}\underset{}{\overset{\leftharpoonup }{B}}}{\partial \text{}t}& =& \underset{}{\overset{\leftharpoonup }{0}}\\ \nabla \text{}·\underset{}{\overset{\leftharpoonup }{B}}& =& 0\end{array}}\\ \downarrow & & \uparrow \\ 3435.313061210916151.091& \to & د\left(س\right)=\{\begin{array}{cc}\sum _{ٮ=1}^{ص}{س}^{ٮ}& \text{إذاكان}س>0\\ {\int }_1^{ص}{س}^{ٮ}ءس& \text{إذاكان}س\in م\\ \mathrm{طا}\pi & \text{غيرذلك}(\text{مع}\pi \simeq \mathrm{3,141})\end{array}\end{array}$
