Typing Formula Steps in a Grid

Good day all, I am a new Mathematica Home user. While typing out the workings for a formula in a Grid, Mathematica complains that the operators are protected and will not display the formulas. The first Grid works fine: Grid[{{Style["Excess Return", Bold], Style["Relative Return", Bold]}, {Subscript[R, p] - Subscript[R, B], Subscript[R, P]/Subscript[R, B] - 1}}, Dividers -> {{False, True}, {False, True}} ] // TraditionalForm Then when I do an example grid I expect to see the assignments in the top row and the workings in the second row. Grid[{{Subscript[R, p] = 0.03, Subscript[R, B] = 0.02}, {Subscript[R, p] - Subscript[R, B] = 0.03 - 0.02 = 0.01, SpanFromLeft}}] However, all I get back is the following two errors: Set::write: Tag Plus in -0.02+0.03 is Protected. >> Set::write: Tag Plus in -0.02+0.03 is Protected. >> And this grid: { {0.03, 0.02}, {0.01, \[SpanFromLeft]} } May someone guide me to the correct section of the help to fix this? Thanks, Ride
