Hi, I tried with \shorstack and work good, but I must add \\ for the new 
line. While \usepackage{mathtools} and \mathclap like say Mohammed this 
work perfect and elegant.

The only problem that I found with \mathclap it is that if the sentence 
is too long, mathclap don't cut in a new line. In this case I use a 
combination between \mathclap and \shorstack.

Thanks a lot!
