I guess my description was a little ambiguous. When I say sum of the numbers, I mean the sum of the numbers in the column. So, for the resulting value of 62, the sum of the first three numbers is 9. The forth number in the column is 7. So, 1 gets the multiplier of 2 and 6 gets a multiplier of 10 --> 2*1+6*10=62.

Make more sense now?
