        "reasoning_content": "\nOkay, the user is asking 2+2*5. Let me think about how to approach this. First, I remember that in math, there's an order of operations, like PEMDAS. That stands for Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. So multiplication comes before addition.\n\nSo the problem is 2 + 2 * 5. According to PEMDAS, I should do the multiplication first. 2 times 5 is 10. Then add the 2. So 2 + 10 equals 12. Wait, but sometimes people might forget the order and add first, which would be 4*5=20, but that's wrong because multiplication has higher precedence. Let me double-check. Yeah, multiplication before addition. So the correct answer should be 12.\n\nWait, let me make sure. Let's break it down step by step. The expression is 2 + 2 * 5. The multiplication part is 2*5, which is 10. Then add the 2 to that result: 2 + 10 = 12. Yep, that's right. I think that's the standard way to solve it. If there were parentheses, like (2+2)*5, then it would be 4*5=20, but there are no parentheses here. So the answer is 12.\n\nAnother way to think about it: in most programming languages, the order of operations is the same, so if you type 2+2*5 into a calculator or a code, it should give 12. Let me confirm with a quick calculation. 2*5 is 10, plus 2 is 12. Yep. So the user might be testing if I know the order of operations. Maybe they're a student learning basic math. I should explain the steps clearly so they understand why it's 12 and not 20. Let me make sure to mention PEMDAS or the standard order of operations to clarify the reasoning.\n"
