For the past few weeks, when asking about mathematical expressions, Aria provides the expressions in a format that is hard to read.

For example, I asked how to calculate a reflection vector, Aria then output the following :

The reflection vector can be calculated using the formula: \mathbf{R} = \mathbf{I} - 2(\mathbf{I} \cdot \mathbf{N}) \mathbf{N} ]$$
