                "reasoning_content": "This is asking for the sum of the first 100 positive integers. There's a famous formula for this, often attributed to Gauss.\n\nThe formula for the sum of the first n positive integers is:\nSum = n(n+1)/2\n\nSo for n = 100:\nSum = 100(100+1)/2 = 100(101)/2 = 10100/2 = 5050\n\nLet me verify this makes sense by thinking about it another way. We can pair up numbers from opposite ends:\n1 + 100 = 101\n2 + 99 = 101\n3 + 98 = 101\n...\n50 + 51 = 101\n\nWe have 50 such pairs, each summing to 101, so the total is 50 × 101 = 5050.\n\nYes, that confirms it.",
