I want to put some short words in certain subscripts when I am in math mode, for example:
\[W_{total} = \sum{W_i}\]
but I think LaTeX understands this as the product of t, o, t, a and l.
Is in any case this way the right way, or is there any other one?
By the way, I have tried
\[W_{\text{total}}\]
but it is not fine for me. (A bit ugly) Forget that.
