"The fact that you couldn't quite get it to work for more than 3 elements (and the nature of the issue in getting it to work) gave me the feeling that it might be related to the 4-color theorem...It was strange. The thought just jumped into my…"

"The empty set is here but can't be seen :-) (intersection of none, part of outside) I think that nested sets are not convenient because it became quickly messy. My representation does not give the feeling that "{A,B}'" is…"

"Very nice illustration. It seems as though I had it inverted. Thank you for the correction, though I think you could do it either way. It depends how you want to define your Venn Diagram regions. You are defining a region as containing the sets…"

"You should draw a circle for each as in the regular Venn diagram. Only instead of circles for sets A, B, C, and intersections being the overlap, now it will be elements a, b, c, and intersections meaning sets of two or three of those elements."

"thanks for your valuable reply sir and i didn't get about why you have written null set separately?????"

"I think so, but I haven't tried it out for anything more than a set of 3 elements. But the procedure should go something like this: Write each element of the set down. Draw a circle around each element. Draw a circle around every possible…"

"Doesn't it come from all the definitions? A finite set has a finite number of elements. The empty set is considered finite, with cardinality zero"

### Introducing Math Concepts

The objective of setting this group is to aggregate ideas and strategies for introducing a Mathematics concept in a classroom at all levels. I think right start would definitely help in making lesson easy to understand as well as interesting.
