MathJax and left align

See http://docs.mathjax.org/en/latest/tex.html.

align

Some words on a line then some display math \[ \begin{align*} y&=\frac{a_1}{b^2}\\ 12345&=x^12,98 \end{align*} \] then some more words on another line, then some inline math \( \begin{align*} y&=\frac{a_1}{b^2}\\ 12345&=x^12,98 \end{align*} \) and some more words and an html P tag (br tag not enough space between line and math)

\( \begin{align*} y&=\frac{a_1}{b^2}\\ 12345&=x^12,98 \end{align*} \) and some more words.

align - with hspace trick

\[ \begin{align*} A &= \pi r^2 \hspace{50cm}\\ &=\text{area} \end{align*} \] \[ \begin{align*} A &= \pi r^2 \hfill \hspace{5cm} \\ &=\text{area} \end{align*} \]

align - with css - no effect

\( \style{text-align:right;} { \begin{align*} y&=\frac{a_1}{b^2} & \\ 12345&=x^12,98 & \end{align*} } \)

this is a new line \( \style{ background-color:yellow;} { \begin{aligned} y&=\frac{a_1}{b^2} & \\ 12345&=x^12,98 & \end{aligned} } \) this is a new line

align - with extra ampersand

\[ \begin{align*} y&=\frac{a_1}{b^2} & \\ 12345&=x^12,98 & \end{align*} \]

flalign - not part of mathjax

\[ \begin{flalign*} y&=\frac{a_1}{b^2}\\ 12345&=x^12,98 \end{flalign*} \]

array

this is a line \[ \begin{array}{|l|l|} \begin{aligned} y&=\frac{a_1}{b^2}\\ 12345&=x^12,98 \end{aligned} & \sum_0^n 2^i \hfill \\ \end{array} \] this is a line
