Well, not quite: the subscripts in HTML are too big  and the first formula in
the PDF does not have superscripts (it still has the carets): I checked LaTeX
export and the problem is present there:

  y = x$_1$\^{}2 + x$_2$\^{}2

  y$^2$ = 2x$^2$ + 1

  z$_2$ = x$_1$ + x$_2$ + 2 (y$_1$ + y$_2$ + r)

PS. The exponent in the last formula (i.e. the 4) is absent from the org
    file: cut-n-paste problem?
