I’m not sure whether I agree with you or not. The four terms in the equation don’t have nearly as much predictive power as one might hope to obtain from an equation: specifically, we don’t really know what units any of the four quantities are measured in.
On the other hand, having an equation does give us marginally more data than your preferred presentation does. At least we know that the relationship looks more like (E)(V)/((I)(D)) as opposed to, say, (E+V)/(I+D), or some such. I do feel that having an equation present (with the appropriate mathematical disclaimers) helps me gain an intuitive understanding of the concept presented.

Edit: Fixed order of operations.
Dorikka,
See here.
I now understand. Thanks.
