1+-1+-1+-2+2+1+-1+-2+-2+-2+-2+-1+2+-1+2+-1+-2+-2+2

Let's simplify the expression step by step:

1. Start with the original expression: \[ 1 + (-1) + (-1) + (-2) + 2 + 1 + (-1) + (-2) + (-2) + (-2) + (-2) + (-1) + 2 + (-1) + 2 + (-1) + (-2) + (-2) + 2 \]

2. Combine the positive and negative numbers separately:

   Positive numbers:
   \(1 + 2 + 1 + 2 + 2 + 2 = 10\)

   Negative numbers:
   \((-1) + (-1) + (-2) + (-1) + (-2) + (-2) + (-2) + (-2) + (-1) + (-1) + (-2) = -13\)

3. Now, combine the totals: \[ 10 + (-13) = 10 - 13 = -3 \]

Therefore, the result of the expression is \(-3\).
