Description fkereki 2003-09-30 02:16:08 UTC 
I want to align different formulae, so the "equals" signs line up. The way I 
found to do it was using "matrix" as in

matrix{a#{}={}#1+2+3+4+5+6+7+8+9+...+n ##{}#{}={}#{n(n+1)} over 2} 

The problem with the code above is that the n(n+1)/2 appears centered, too 
separated from the equals sign. However, if I write

matrix{a#{}={}#1+2+3+4+5+6+7+8+9+...+n ##{}#{}={}# alignl {{n(n+1)} over 2}} 

then both numerator and denominator get "alignl'ed", which looks quite ugly.

I tried adding a "alignc" writing the last term as below, but it doesn't work. 

alignl { alignc{{n(n+1)} over 2}

How do you align the equals signs?

Try this:
matrix{a#{}={}#1+2+3+4+5+6+7+8+9+...+n ##{}#{}={} #alignl {n(n+1)}
over {alignc 2}}

Is this what you tried to get?

much shorter:

matrix{a#{}={}#1+2+3+4+5+6+7+8+9+...+n ##{}#{}={} #""{n(n+1)} over {2}
                                                   ^^
Empty string -> makes the expression left-aligned without changing the
rest...

OK, thanks! The first solution was the one I was shooting for, but 
the second one (the sneaky trick with the "") is quite good, too!

OK, solved!
