Here is an example: \setupcolors[state=start] \def\solutionbox {\dosingleempty\dosolutionbox} \def\dosolutionbox[#1]% {\mframed[width=2em,background=color,backgroundcolor=lightgreen,#1] {\strut}} \starttext Not aligned \startformula \startalign[n=1] \NC 6 + 7 + 4 = \solutionbox \NR \NC 16 + 5 + 4 = \solutionbox[width=1cm] \NR \NC 6 + 200 + 4 = \solutionbox[width=3cm] \NR \stopalign \stopformula aligned \startformula \startalign[n=7,align={right,middle,right,middle,right,middle,left}] \NC 6 \NC + \NC 7 \NC + \NC 4 \EQ \NC \solutionbox \NR \NC 16 \NC + \NC 5 \NC + \NC 4 \EQ \NC \solutionbox[width=1cm] \NR \NC 6 \NC + \NC 200 \NC + \NC 4 \EQ \NC \solutionbox[width=3cm] \NR \stopalign \stopformula Two column \startformulas \startformula \startalign[n=7,align={right,middle,right,middle,right,middle,left}] \NC 6 \NC + \NC 7 \NC + \NC 4 \EQ \NC \solutionbox \NR \NC 16 \NC + \NC 5 \NC + \NC 4 \EQ \NC \solutionbox[width=1cm] \NR \NC 6 \NC + \NC 200 \NC + \NC 4 \EQ \NC \solutionbox[width=3cm] \NR \stopalign \stopformula \startformula \startalign[n=7,align={right,middle,right,middle,right,middle,left}] \NC 6 \NC + \NC 7 \NC + \NC 4 \EQ \NC \solutionbox \NR \NC 16 \NC + \NC 5 \NC + \NC 4 \EQ \NC \solutionbox[width=1cm] \NR \NC 6 \NC + \NC 200 \NC + \NC 4 \EQ \NC \solutionbox[width=3cm] \NR \stopalign \stopformula \stopformulas \stoptext Aditya ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : https://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________
