This trap comes up all the time in the GRE and GMAT and yet many people fall for it. It's to do with algebra, factoring, cancelling and what assumptions we can and cannot make in the quant sections of these tests (as well as many others!).

It took me a while, but I finally understood the last case haha If x > 0, say, 4, y can be 0 and the equations will hold: 4 * 0 = 0^2. So C is wrong because x can be > 0 and y = 0 (y doesn't need to be > 0). However, if y < 0, say, -1, then x must be negative (= -1) so that x -y = -1 - (-1) = 0. Thanks!

I started studying for GRE, so glad I discovered these videos: my practice test scores are going up and my test times are going down! Thank you for the clear, concise and engaging content, I'll probably keep watching these after I (hopefully) ace the test!

Wow thanks Guy, much appreciated. Please do

Yes Philip, I fell for these traps and would love your further videos and explanation if possible on this topic as I am preparing for GRE. Thanks 👍

@MrMcfire2 Месяц назад

This is a fantastic method to complement the standard "choosing numbers" strategy. The more 'tools' we have the greater the probability of getting the answer correct!

@shrutijaiswal1647 2 года назад

In the 2nd example, can p = -3 ,-5 and so on ? Are negative numbers not considered prime ? (Odd prime numbers less than 5 )

@emuobooyagbarha9363 2 года назад

Honestly I fell for all the tricks and traps. I need more guidance

@sumaiyaaralima3563 3 года назад

Hi Sir!!! How are you?? First Comment 😀✌️ I was eagerly waiting for your video😁

@TheTestedTutor 3 года назад

Second! I am good, hope you are well too! :)

@hemantyadav3426 11 месяцев назад

hey philip, for second question we know p=q and pq >0 can p and q both be negative?

@nnaemekacephas5931 5 месяцев назад

If you had an issue understanding the logic behind the last choice of option D, then this might help. Y = 0 or x=y... these are the only two possibilities that make y(x-y) = 0 to be true. Recall that the question asks which one statement must be true (in the options). Statement 1: "If x>0, then y > 0", it says assuming x is bigger than zero then y would be bigger than 0 too. That holds true for the part x = y but then y may be 0 still because of the second possibility. But "if y

@rajjain8915 2 года назад

Could you explain again the last one

@tenimakkani838 Год назад

I have no freaking idea what happened in the last example. Tried watching it a 100 times and going through comments it still doesn't make sense. I wanna cry, why am I so shit at math

@eceyagc2563 7 месяцев назад

for the last example why couldn't we say that since y^2 has to be positive, xy > 0? is it because y was not in parenthesis?

@salimabendjabeur532 2 года назад

Hi Phil , i am confused, how is this different from permutations? why not do A!*B!*C! ?

@akshitharavi1995 2 года назад

Omg!!! The last problem is totally confusing

@marielleworoboff8717 3 года назад

Quick Comment: For the third problem you showcased I was wavering between answer choice C and D. I noticed that if we choose y=-4 than x=-4 for the primary equation to be sound. for instance we can't have y=-4 and x=4 because then xy will not equal y^2. In this case, it proves answer choice D. Is this a smart way to go about solving this problem?

@TheTestedTutor 3 года назад

A very good way yep

@charleneconstantino1618 3 года назад

hi, so is the asnwer for the first question D? unable to determine? thanks

@TheTestedTutor 3 года назад

Yes, correct

@surbhiagarwal2322 11 месяцев назад

If the first question pops up in quant comparison, is it safe to say the answer will be option D?

@ToothlessMass08 2 года назад

Fell for C in the last one. Thanks for the heads up as usual!

@Pokexiu 2 года назад

Hi Philip! Just to confirm, so we can cancel out variables only in the case that we are sure that they are not zero, right? is there a reason for this?

@TheTestedTutor Год назад

Yes! Fractions can't have zero as a denominator!

@sudhanshumaurya2860 3 года назад

Please try to make videos on quant tricks and traps on every topics, every week. That would be really helpful for us. Btw much love man

@TheTestedTutor 3 года назад

I will try my best, takes a lot of work away from my fulltime job

@melikanazari1306 3 года назад

🥺 I just had my GRE test yesterday and I messed it up 😥 English is not my first language and 2 months studying wasn't enough. I'm so disappointed 😞 😔

@TheTestedTutor 3 года назад

Sorry to hear that Melika. Improvement is always possible, it is just a question of time/budget/effort etc

@navinbondade5365 3 года назад

in the second question it says p is less then five that means P can also be a negative number ?

@TheTestedTutor 3 года назад

Yes, normally, unless stated otherwise

@dennismungania6044 2 года назад

They said p is odd prime and p

@navinbondade5365 3 года назад

The cancelling them should be get confirm first?

@TheTestedTutor 3 года назад

Or don't cancel if you can't confirm they are not zero

@mukundasharma8856 2 года назад

Didnot understand the last one

@ravinalad7481 3 года назад

Hi , I have tried with mock tests and my quant score was between 167 max to 160. How can I keep it constant ? I tried manhattan, kaplan , ets official test seties

@TheTestedTutor 3 года назад

Constancy is hard, just keep learning from every mistake Ravina!

@selvakumarmunusamy5901 10 месяцев назад

Sir, ab=bc, which answer do I have to choose? This is a QC question if b=0, so both quantities are equal. The answer to this question is C. Let me know, please?.

@nnaemekacephas5931 5 месяцев назад

Consider the case where b=0, a=10, c= -1 and the case where b=0, a=10, c=10. You will notice that a and c can take any value you choose and the equation would still hold true so long as you make b = 0. The first case means that 3a is greater than 3c, while the second case means that 3a equals 3c. So that's option D

@isa0471 2 года назад

I am having trouble understanding how you reach the conclusion of the last example. I don't quite understand how you chose between c and d. Somebody help me.
