According to your suggestion, we can use \startmatrix for 3,4,5, but how to put text?

Do you also want equation numbers? If so, then that is not supported by ConTeXt at the moment. If you do not want equation numbers, you can use \startformula \startalign[n=1] \NC equation 1 \NR \NC equation 2 \NR \NC \startmatrix[left={\left.}, right={\right\}}, n=1, align=middle] \NC equation 3 \NR \NC equation 4 \NR \NC equation 5 \NR \stopmatrix some text here \NR \NC equation 6 \NR \stopalign \stopformula

I googled and found a similar question in LaTeX, but the answer is to use tikz.

With LaTeX, you can also use mathtools package, which is much easier to use.

How do you think?

Math support will be reworked at some stage in MkIV. Aditya
