The most tragic part about mathematics is that students often lack the ability or vocabulary to ask the questions that will really develop their understanding. Instead, they ask vague questions, such as "how do I approach problems like...". Often, I see teachers respond to these sorts of inquiries by shoving equations in the student's face--"just plug in the numbers", they say. I cringe when I see this, because it makes the student think that memorizing an equation is the same as understanding the problem.
When I tutor kids and they ask me something as open ended as that, I tell them to put down their pencil for a minute and take a break. Vague questions are a strong indication that the student is overthinking the problem. That is true on SE as well.
I recommend reminding the OP of the foundation of the problem. It is possible that the question that they are asking is well beyond their current level of understanding. The comments section is a great resource. Ask the OP questions about what they are trying to accomplish. Comment a link to some literature on the topic. Try to get the OP to specify their question.
Ultimately, I would down vote a question like that, unless the OP specifies what it is they are asking.
