When overlapped the 5 Olympic rings enclose 9 regions.



Place each of the numbers from 1 to 9 in a separate region so that:

A + B = B + C + D = D + E + F = F + G + H = H + I = M

where M represents the total of each ring.

How many values for M can you find?
How many arrangements for each M can you also find (discount total reversal of order)?

Thanks, Penny. Correction made. And for your note, I had also missed a second arrangement for one value of M on my first pass.
