I'd like to know where you had a problem, though...

  • I get an error when I execute the above code. – Teja Nov 4 '12 at 0:56
  • @Vutukuri That code works without error for me. Perhaps tell us what error message you got. – Stefan Kottwitz Nov 4 '12 at 0:59


    0.632 \times 0.5 + 0.368 \times 1 
  \right] = 0.684


The only problem is to determine the size of the brackets. From the sample it seems that in this case the size is given by the fraction before the summation. The solution is based on using \vphantom,

which makes an invisible box whose height and depth are the same as those of the corresponding \phantom, but the width is zero (Knuth, TeX Book)
