Ask HN: Do you have standard questions for understanding math equations?

When I'm studying a Math equation I usually have a list of questions that I use to "poke" my understanding of the equations. Here are the ones that I use the most:

- What variable has the biggest impact on the output? - What variable has the smallest impact ? - Predictions - What happens when variable X is zero? - What happens when variable X increase? - What happens when variable X decrease? - For each increase in variable X how much I need to decrease Y to stay the same?

Does any one have pointers to a list of "reading comprehension" questions for math equations?
