Hi all, For some strange reason, I want to type into Mathematica an expression that should look like T^a_b, that is, the b subscript of T raised to the a power. My exact key strokes are T Ctrl-^ a Ctrl-space Ctrl-_ b. However, when I enter this expression into mathematica, it adds (spuriously in my mind) some parentheses, so that I get (T^a)_b. I would like to know what causes these parentheses to be added, and if there is anything I can do to prevent them from appearing. What I have to do now is go back into the expression and edit out the parentheses. Carl Woll Physics Dept U of Washington
