      1. works, but any following text is in tt

  2.

math> |r| \qquad\qquad\qquad\qquad\qquad   </math> 2.

  3.

math> \qquad\qquad\qquad\qquad\qquad |r| \;</math> 3.

leading and trailing math spaces absorbed.

.   4. This sort of works

.                               math> |r| \;</math> 4. 
  5.
 : math> |r| \;</math>                               5. 

This, of course, works for single lines.

      6.
 nbsp; +nbsp;  math> |r| \;</math> 6.
      7.
+nbsp;+nbsp;+nbsp;+nbsp; math> |r| \;</math> 7.

These seem work, on my browser.

              8.
 :  nbsp; +nbsp; +nbsp; +nbsp; +nbsp;  math> |r| \;</math> 8.
              9.
 : nbsp;+nbsp;+nbsp;+nbsp;+nbsp;+nbsp;+nbsp;+nbsp;+nbsp;+nbsp; math> |r| \;</math> 9.

These don't work, leading spaces get absorbed back to the : indent.

.   10. This sort of works.

This is not indented, "="s aligned, right side left-aligned.

  12.
 
 
 : math> |r| = \sqrt{x^2 + y^2 + z^2} \;</math>   12.
 ::    math> = \sqrt{x'^2 + y'^2 } \;</math>  
 :: math> = 42 \;</math> 

This is indented, "="s ~aligned, right side left-aligned.

  13.
 : math> \begin{matrix}
  |r| &=& \sqrt{x^2 + y^2 + z^2} \\
      &=& \sqrt{x'^2 + y'^2 } \\
      &=& 42 \\
      &=& 42 \qquad\qquad\quad \end{matrix} </math>   13.

This is indented, "="s aligned, right side centered. Too much space around the "="?

This is indented, "="s aligned, right side left-aligned. ...Um, it was indented.
