I use Mathematica 4.0 to generate notes for my courses in physics. However, when I revise these notes, I often insert or delete equations thereby changing all of the succeeding equation numbers. Is there a way to tag references to these equations in the text so that when the equation number changes, the corresponding text changes as well. For example a + b + c = 0 (1) Equation (1) is ... If I now insert another equation before (1), how can I work it so that the text automatically changes to Equation (2) is ... Thanks, Kevin
