: : : {1/[s^(-1)]}+{1/[t^(-1)]}/[{s^(-1)}{t^(-1)}]=
: : *****************************************
[{1/[s^(-1)]}+{1/[t^(-1)]}]/[{s^(-1)}{t^(-1)}]= ... the bolded parentheses were not there in the original problem
[{1/[1/s]}+{1/[1/t]}]/[{1/s}{1/t}]=
[{s}+{t}]/[{1/st}] = st(s+t)
: : *****************************************
: : : I found it to be
: : : s+t
: : : did I do that right?
: Hmmmm; I get st(s + t) ???
