4 years ago This is not unexpected behavior, but certainly not desirable. Normally Asciimath removes brackets around numerators and denominators, so that something like (x+4)/4 will display without parens in the numerator. But that unwrapping is probably not desirable for matrices/vectors.
I'll make a fix so it skips the bracket removal for matrices.
In the meantime, you can fix the display by adding an additional bracket around your numerator, like ([[1,2,3]])/2
The vector
[[1, 2, 3]]renders as a row vector, complete with square brackets. If you divide by anything though, those square brackets vanish:[[1, 2, 3]]/2. I'm not sure this is the intended behavior!
