Answer 2

Let's solve the arithmetic expression step by step:

2 + 2 + 1 - 5 + 9 - 4 + 10 - 15 + 1

Step 1: Add the first two numbers. 2 + 2 = 4

Step 2: Add the result to the next number. 4 + 1 = 5

Step 3: Subtract the next number. 5 - 5 = 0

Step 4: Add the next number. 0 + 9 = 9

Step 5: Subtract the next number. 9 - 4 = 5

Step 6: Add the next number. 5 + 10 = 15

Step 7: Subtract the next number. 15 - 15 = 0

Step 8: Add the last number. 0 + 1 = 1

The final result is 1.
