Bookmark my article as a reference for high school math.
As always, I also publicize my article in DeHaan Services ("My Definitive Quick Reference Guide to All Numbers").
I contacted my editor at Decoded Science to update the two previous articles that had led to this one. We needed to add the forward-pointing links so the readers could follow the information without going back to an index page and guessing what comes next!
Besides, in any online magazine with multiple authors, you have no guarantee that your series will be presented together in the index. Other writers probably submitted articles in the meantime.
Originally, the previous articles had simply said "Next week we will explore...". Now it was time to put in a solid link!
Writing Tip: After completing a series of articles, update the old ones to ensure your readers can navigate through them smoothly and easily. (Do not force them to use the main index).
