Please Note

I have a suggestion to contributors to the group: make more use of the "Start a Discussion" link. I think that will keep the content more organised, than using comments to the main page of the group. (Colin McAllister)

The purpose of this group is to encourage more problem solving on Mathematics24x7. The HTML editor supports small images embedded within the text, which would be useful for working on symbolic or algebra problems. Create images of equations using an online equation editor, as at CodeCogs or Thornahawk. I hope that you will pose problems, not only to know the answer, but also for practice in online dialog, in technical presentation, and for studying the methods of mathematics.

So glad I found this. Will come back and contribute! My site is evolving and I am having fun with it in retirement but I love all the math you have going on here!
