What's the simplest way to prevent an array index "i" inside square brackets in a mathematical expression from being interpreted as code to italicize text by the forum editor?(adsbygoogle = window.adsbygoogle || []).push({});

My work around is to put a space before the "i" in Latex expressions, but this is slightly inconvenient.

For example [itex] A[\ i][j] = \beta [/itex] displays properly.

and [itex] A[j] = \beta [/itex] doesn't.
