I am trying to write a mathematical equation in jupyter notebook markdown, this equation have a Curly brace '{' symbole. I wrote this code : 

$$M=\begin{equation}
\left\{ 
  \begin{aligned}
    2\,x&+3\,y&-4\,z&=&7\\
    -x&+8\,y&   &=&3\\
    \frac{2}{3}\,x&+\frac{13}{2}\,y&-5\,z&=&\frac{14}{5}\\
  \end{aligned}
  \right.
\end{equation}
$$


when running the cell I get this:

instead of the correct one:

So I don't know what the problem is, any idea? PS: I have python3

  • It's using the wrong font. Have you tried clearing your browser cache and loading again? Are you trying to set any fonts? – ChrisGPT was on strike Jan 18 '20 at 14:03
  • Is what you see reproducible if you go [here](https://github.com/binder-examples/requirements) and click `launch binder` and then paste your code in a notebook after session comes up? (The result looked good when I did.) – Wayne Jan 19 '20 at 00:53
  • @Wayne thank you, what you said worked correctly but how can I fix the problem in my localhost? – khadija.EL Jan 19 '20 at 09:44
  • @Chris I opened my notebook file in a new navigator but nothing changed, the only thing I wrote is that code – khadija.EL Jan 19 '20 at 09:54
