Transitive Property - A new one for me - Thanks Alan  

Use the calc on the home page

65-129

Mmm

zero elements 1

one element    5

two elements   5C2=10

3 elements     10

4 elements       5

5 elements        1

TOTAL = 32

Mmm same answer as CPhill.   Now the question is "why are these the same"   

Who want to provide a proof that these methods will always result in the same answer?

Use the calculator on the home page :)

What does it mean Geno?  I do not understand the question. :/

Happy Christmas Eve Jilly :))

Sounds good to me Geno  :)
