    8. 

  8.  *  Prevents the TeX error messages from being displayed and shows the
    9. 

  9.  *  original TeX code instead.  You can configure whether the dollar signs
    10. 

  10.  *  are shown or not for in-line math, and whether to put all the TeX on
    11. 

  11.  *  one line or use multiple-lines.
    12. 

  12.  *  
    13. 

  13.  *  To configure this extension, use
    14. 

  14.  *  
    15. 

  15.  *      MathJax.Hub.Config({

  31.  *      });
    32. 

  32.  *  
    33. 

  33.  *  Display-style math is always shown in multi-line format, and without
    34. 

  34.  *  delimiters, as it will already be set off in its own centered
    35. 

  35.  *  paragraph, like standard display mathematics.
    36. 

  36.  *  
    37. 

  37.  *  The default settings place the invalid TeX in a multi-line box with a
    38. 

  38.  *  black border.  If you want it to look as though the TeX is just part of
    39. 

  39.  *  the paragraph, use
    40. 

  40.  *
    41. 

  41.  *      MathJax.Hub.Config({
    42. 

  42.  *        TeX: {
    43. 

  43.  *          noErrors: {
