1. The problem is to find the sum of the given list of numbers. 2. The formula for the sum of a list of numbers $a_1, a_2, \ldots, a_n$ is: $$\text{Sum} = \sum_{i=1}^n a_i$$ 3. We add all the numbers step-by-step: $$-170 - 250 - 250 + 500 - 205 - 300 + 580 - 49 - 100 - 300 - 200 - 500 - 50 - 100 - 70 - 55 - 170 - 155 - 155 - 200 + 95 + 200 + 300 + 390 + 390 - 250 - 170 - 200 + 490 - 300 + 590 + 320 - 200 - 250 + 490 + 600 - 250 - 250 - 200 + 390 - 250 - 250 + 490 - 49 - 327 - 200 + 390 - 300$$ 4. Calculate the sum: First, sum all positive numbers: $$500 + 580 + 95 + 200 + 300 + 390 + 390 + 490 + 590 + 320 + 490 + 600 + 390 + 490 + 390 = 6335$$ Then sum all negative numbers: $$-170 - 250 - 250 - 205 - 300 - 49 - 100 - 300 - 200 - 500 - 50 - 100 - 70 - 55 - 170 - 155 - 155 - 200 - 250 - 170 - 200 - 300 - 200 - 250 - 250 - 200 - 250 - 250 - 49 - 327 - 200 - 300 = -6666$$ 5. Now add the positive and negative sums: $$6335 + (-6666) = -331$$ 6. Therefore, the total sum of the numbers is: $$\boxed{-331}$$
