What I'd like to see, is for you to use the operators, algebra and calculus you known to present a practical solution? Can you post one that can be verified by executing in MS SQL Server or Access?

To see if your knowledge of operators, algebra and calculus is sufficient to post a practical/verifiable solution.

If anyone was successful in verifying the above solution, please post the steps :) Received on Thu Apr 13 2006 - 22:10:12 CEST
