Can't fix this missing $ inserted

[SeM]

Hi, I have this math text:

$\begin{math}x'=\Re\,\left\{x(t)\right\}, y'=\Re\,\left\{y(t)\right\}, z'=\frac{1}{2} \big(\Im\,\left\{x(t)\right\}+\Im\,\left\{y(t)\right\}\big)\end{math}.$

however it is not accepted.

can you check the tex code under "Math processing error" and see an error?

what part is wrong here?

What are \begin{math} and \end{math} for? Also, I don't understand the presence of all those $.

Those $ are inserted to get the { in the middle of the expression.

\being{math} and \end{math} is used because sharelatex recommended it for this section.

MathJax can't do anything with those, hence the processing error.

What you get is
$x'=\Re\,\left\{x(t)\right\}, y'=\Re\,\left\{y(t)\right\}, z'=\frac{1}{2} \big(\Im\,\left\{x(t)\right\}+\Im\,\left\{y(t)\right\}\big).$
which doesn't like anything one would write. To get a curly bracket {, simply precede it with a backslash, \{.

Worked! Thanks!
