The rule of this variant is:
Outside in left side there is a number, this number is the SUM of three numbers in that row: the first number is formed by the digits in the first four columns, the second number by the digits in columns 5,6 and 7, the third number by the digits of the last two columns.
For example if the row is 1,2,3,4,5,6,7,8,9, outside there is written "1890" because
1890 = 1234 + 567 + 89.
I hope you have understood.
Bye, bye.
