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

\[
\begin{flalign*}
y&=\frac{a_1}{b^2}\\
