Subtract the number on the left from the number on the right, and write the difference between the two numbers to generate a new number string: 3,6,9, - 1,8, which is called the first operation. After the second operation, a new number string can be generated: 3,3,6,3,9, - 10, - 1,9,8. Continue to operate like this, and ask: (4) use your conjecture to calculate the sum of all numbers of the new number string generated after the 2010 operation?
