Hi all,
I have a math equation question too. This has made me pulling my hair off, for a while. Please see below: (snip)

Hi, I think the point is to use a \cr after each line of aligned text in \cases. On my installation the following works fine: \usemodule[amsl] \starttext \startformula {\bf f(x)} = \cases{ \sum_{x=1}^n x &\quad if I am false \cr \displaystyle % just to see the difference \sum_{x=1}^n x^2 &\quad \text{if I am true} \cr } \stopformula \stoptext Note that I added a \quad after each "&" in order to have a little more space: however this is not essential. Best regards: OK
