1. The problem is to find the sum of the given numbers: 2140, 604, 3715, 861, 1840, 711, 140061, 589, 39980, 6168, 4000, 15998, 395, 4000, 15998, 399, 13100, 4000, 79, 6999. 2. The formula for the sum of a list of numbers $a_1, a_2, \ldots, a_n$ is: $$\text{Sum} = \sum_{i=1}^n a_i = a_1 + a_2 + \cdots + a_n$$ 3. We add all the numbers step-by-step: $$2140 + 604 = 2744$$ $$2744 + 3715 = 6459$$ $$6459 + 861 = 7320$$ $$7320 + 1840 = 9160$$ $$9160 + 711 = 9871$$ $$9871 + 140061 = 149932$$ $$149932 + 589 = 150521$$ $$150521 + 39980 = 190501$$ $$190501 + 6168 = 196669$$ $$196669 + 4000 = 200669$$ $$200669 + 15998 = 216667$$ $$216667 + 395 = 217062$$ $$217062 + 4000 = 221062$$ $$221062 + 15998 = 237060$$ $$237060 + 399 = 237459$$ $$237459 + 13100 = 250559$$ $$250559 + 4000 = 254559$$ $$254559 + 79 = 254638$$ $$254638 + 6999 = 261637$$ 4. Therefore, the total sum of the numbers is: $$\boxed{261637}$$ This means if you add all the numbers together, the result is 261637.
