- 2. Arrange 3 numbers in turn (4) Use your conjecture to calculate the sum of all the numbers of the new number string generated after the 2010 operation? 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?
