If you could make "double-check glasses", you certainly wouldn't need an MBA to make it big with that. Ron, what are you talking about? That's what I am thinking every single day! (You may joke, but I’d like to interpret it in this way) I cannot create double-check glasses, but I’m pa...

I exactly read "both on its size and on climate", (not "on both its size and on climate"). Does wearing double-check glasses help? :(

Hey You (with all the hair)! You're coming back with a different style in writing (pretty close to the gmat-RC style), but I still get what you're saying when I see Ron's "tail" Which is great if you can think of such tricks ... but not if you can't. Fair enough. I see the world of people ...

Thanks Matt for your great response! That analogy works well for consecutive squares, which do get further apart (1, 4, 9, 16, 25, etc.) How do I know whether I use a right analogy in a short time if I know little about math "rules"? My answer for my question would be: analogy is a form of...

From Uva’s question, I’m wondering how could we know (201*201*301 – 200*200*300) is bigger than (200*200*300 – 199*199*299)?
(if we don’t have calculator)

Could we use an “analogy� such as: (11*11-10*10) > (10*10-9*9) ?

Uva, I think the question asks the difference between “the actual capacity of the box� (the old box) and “the capacity computed using these measurements� (the new box with error) In case the new box becomes biggest (added 1cm to each dimension): --> the difference = (capacity of new box – ...

So what does this question actually test? Thinking practically? Any tool that can kill the beast is useful. None discrimination between a sophisticated tool and a hand-made tool?

I use analogies because the human brain is fundamentally wired for analogies/examples/experience, and not for rules. Think about how you learn your first language, of which your knowledge is incredibly thorough. (Even if a professional linguist studies your language for years and years, (s)he will ...

maybe this is a reason why you like teaching us the analogy technique (making superior guys digestible)

Two things here: 1/ To summarize... You thought of one interpretation that works, and another that doesn't. To that I say: Ok, you found an interpretation that works! Where's the problem? Just ignore the interpretation that doesn't work. 2/ In this context, there's no doubt that "monkfish"...

Some people call me things I can't write here. (: Humm, we often keep a secret because we think only we have. Actually, it can be an universal phenomenon :) There's always "Hey you (with all the hair)", I suppose. Haha, you still remember the historical story. Do you think I'm "stric...
