Thanks @Erol!
Just had some time and decided to draw up a quick example for people that don’t follows links and this way it’s a bit more obvious in the post itself as well. (I’m using French braille instead of Nemeth by the way.)
5^2 \sqrt{3}\neq5^{2\sqrt{3}}

For those of you that don’t have a binary system yet but images for 00…99, here’s how you read the binary as decimal:
① ①
② ②
④ ④
Two columns make a cell and if a dot is raised for that column you add it, so you’ll alway have a value between 0 and 7 in each of the two cells. In the end you can encode the above math expression using your existing PAO system with just 5 locations. Best of all, there is absolutely no ambiguity!
