So we need to compute the sum.\n\nThe formula for the sum of the first n natural numbers is S = n(n+1)/2. For n=100, S = 100*101/2 = 50*101 = 5050.\n\nThus, the answer is 5050.\n\nWe should output the answer clearly. The question is in Chinese, but the answer is a number. We can respond with just the number or a short explanation. Since it's a simple arithmetic problem, likely just the answer is expected.\n\nBut since the instruction says \"You are an AI assistant that responds to the user's questions,\" I'll provide a concise response.\n\nFinal answer: 5050."
