LaTeX Error

Hello,

The LaTeX feature of Documents is the best, really!

Yet is seems the support is not complete.
For instance, try this:

  1. \begin{align*}
  2. \frac{a + b}{a} & = \frac{a}{a} + \frac{b}{a} \\
  3. & = 1 + \frac{b}{a}
  4. \end{align*}
This generates "Invalid Expression" while it works perfectly on CodeCogs LaTeX Equation Editor.

The result looks like that:



Thank You.
