    Gary,

    would you mind re-reading my posting, particularly the last 2 or 3 paragraphs?

    I followed your mulitplication on your form:

    http://fer3.com/arc/imgx/hav-DONIOL-worksheet-2.pdfhttp://fer3.com/arc/imgx/hav-DONIOL-worksheet-2.pdf

    But it appears that you only got the right answer (truncated) by adding a "fudge factor" of "6." Without that you would not have gotten the correct answer. You said it is a "carry," a carry from where? If this method of multiplication is good then why doesn't it produce the correct answer of 12196860 that could be rounded off if needed. Where are the rest of the digits in the multiplication result?
