I’m willing to take up GRE in August 2016. The post and comments are dated of 2012. Will the same ebooks help me in preparing now? Or any upgrades versions are available. Got confusion because of dates on posts.. Please reply

Thanks

Hi Rakshith,

Thanks for reaching out!

We regularly introduce new blog posts and update our materials. In the case of this eBook, for example, there haven’t been a lot of adjustments needed. The formulas for mathematical topics don’t change regularly, and the GRE itself has not updated the broad types of math content it has, so a resource like this one doesn’t need to be regularly remade.

We are continually engaged with updated resources, though, and our book reviews posts will reflect this, showing yearly (or sometimes even more frequently!) updates as new editions of books are released, for example.

Don’t worry! We haven’t let things get stale.

Hi,

I’m not sure if this problem is being faced by anyone else, but in the PDF version of the Math GRE Formula eBook there appears to be some issue with certain formulae and examples not appearing clearly/ as clearly as the written text. In some cases it is almost impossible to decipher. Any assistance with this would be much appreciated.

Thanks!

Hi there

Thanks for writing in about this! I just downloaded a copy of the PDF version to see if I would encounter similar issues. While I agree that the formulas in the eBook are less clear than the accompanying text due to the equation editor used when creating the eBook, I was able to read all of the formulas without an issue. That being said, I’ve let the content creators here at Magoosh know about your experience so that we can improve the eBook in future editions. However, since we have many projects going on, releasing an updated eBook may take some time. So, in the meantime, please let us know if there is specific formulas or examples that are particular hard to decipher, and we’d be happy to help you out with those

Happy studying!

Hi magoosh Team,

Could you please explain the following property.

Any counting number including negative numbers (e.g. -3, -1, 2, 7…but not 2.5)

Thanks,

Ganga

Hi Ganga

It looks like you’re asking about the definition of an integer. “Counting numbers” refer to all positive numbers with no fractional parts, i.e. the set of numbers {1, 2, 3, …}. The name comes from the fact that these are the numbers that we use to count things. Notice how counting numbers do not include zero or negative numbers. So, in our definition of an integer, we also have to include the negative of counting numbers and zero. As I mentioned, numbers with fractional parts are not integers, so 2.5 (2 1/2) is not an integer. The rest of the numbers listed are whole numbers and are either counting numbers or the negative of counting numbers and are therefore integers!

I hope this clears up the definition

From my little knowledge i think it is more helpful for beginner of GRE exam .for math preparation.

Page 10.

|X| is not equal to X, for X<0, but rather is equal to -X.

Thank you so much for this helpful workbook. I haven’t done math in years and this is a good reminder. My only comment is that only a few of the formulas have examples with them, and it would be helpful to have at least one example for each formula. Thanks!

Hi Magoosh team,

I really appreciate your work with the ‘GRE Math Formula’ ebook. Just started going through it and I’m loving crisp and clear explanations.

One doubt though on page 9 under title ‘Factorizations’ you have explained a method to find how many factors given no. has. e.g. for 720 it is given no. of factors as 30. but that is the no. of only positive factors right? So for the given question we should mention sum of positive as well as negative factors right? so factors of 720 has 60 factors (+ve + -ve)

Let me know if my approach is right or am I giving too much thought to a simple logic.

Thanks & Regards

Hi

I hav recently started using your ebook. Thank you so much for the book/ download

I started on Factorization. I have a question on it.

You said if I were to find how many factor a number has, I can find its prime factorization (2^a x 3^b x 5^c)

where I have 5 choices (0,1,2,3,4) for a, 3 choices (0,1,2) for b and 2 choices (0,1) for c.

The next page, to find the GCF, is to take prime factorization..

56 = 2^3 x 7 <— where does the 7 come from if I were to use your given formula?

70 = 2^1 x 5^1 x 7 <— again, where does it come from? I do not understand..

I have been scratching my head for this other question. If I were to follow your rules, how do you find prime factor and GCF for 24 and 108? If I use your formula there's no way I can get 108.. because I only have 3 choices for b (0,1,2)

All you get when you try to download the pdf is the first page. Where can I get the whole book?

Hey Eileen! You can download it here: http://magoosh.resources.s3.amazonaws.com/Magoosh_GRE_Math_Formula_eBook.pdf

thank you so much. This is helping me a lot

Thanks so much!

Thank you guys.It is really good book and helping me a lot.

thank alot for all the materials, videos ebooks and various other stuff u guys r providing for the GRE….. magoosh i doing a great job…….thank you mangoosh….!!!!!

You’re welcome!

very helpful material U guyz shared .. Great job and THanks alot

I can’t believe you are giving all of these ebooks for free…Great job

Thanks a lot…

you are providing great deal of helpful information and study materials.

Great! I’m glad they are helpful!

You guys rule, no second thought on that.

Wish you could take classroom coaching in India, just a wish.

culdn’t hav had askd for more 😛 but hav to say an outstanding work from all of u

Thanks, Karan!

very helpful site,books and teachers here

Thanks, Abrish!

very helpful your site ,books and teachers here

very helpful book and u also mam

Ma’am,

Well, my math is always better than verbal but i’m really worried about one area related to “medians , quartiles standard deviations” ;their calculation – can you please please suggest a good link or anything else

Hi, Praneeth

That topic is pretty rare, so I wouldn’t worry too much about it, but here are some blog posts and a video to help you out:

Let me know if you have any other questions and I’d be happy to help!

Best,

Margarette

Thanks a lot Ma’am this was exactly what I was looking for ;

one more thing ma’am -in a HISTOGRAM distribution is it enough to know that mean is greater than median?Do we have to learn how to calculate them too?

Usually you will not have to calculate them. Just knowing the distribution and the difference between the mean and median is sufficient.

Hey Chris, Can you come up with a 2 month study plan.. I registered my test date on sep 5

I am going to buy premium package.

Thank You

Hi Srihasha,

Actually, we have a 90 day study guide, which you can compress slightly to accomodate 2-months time frame. A good rule, as to not overburden yourself, is to do at least 80% of the recommended questions on the guide.

Here’s the link :):

Hi Margarette,

Thanks for the Maths formulas book, I found it so helpful for me!

Uhm, I just concern if there is a typo of the Quadratic formula?!

Thanks

It should be fixed now, thanks for catching that! Let us know if you find anything else!

seriously love you guys!! THANK YOU!!

You’re very welcome, I’m glad we could help!

i just started reading the formulas you compiled together. Excellent work, congrats

very useful, especially for those busy with verbal these days and lazy for math

Haha thank you! We’re happy to help

Margarette,

This isn’t germane to the particular topic but do you still do the ‘Practice question(s) of the week’?

I looked at some of your archived blog material and I found the questions to be challenging and educational.

Hi, Sammy

Yes, we discontinued Practice Question of the Week for a variety of reasons, but they were basically just questions and explanations from the database of practice questions in the Magoosh product– if you liked those questions, I’d definitely recommend signing up for a Premium Magoosh account!

Best,

Margarette

Oh okay, thanks! I found most of them to be hard yet feasible. Was this the purpose? Did you guys specifically pick out harder questions for your weekly practice problem?

The weekly questions were usually Medium to Hard. Generally, we avoided posting up particularly Easy ones because those seemed to provide less value to students. It’s more fun to have a tough problem and talk about various ways to tackle it as opposed to a simple practice question with a very straightforward answer :).

You guys did a great job! Definitely will look over this more closely and keep a copy until test day.

Thanks!

Hi, Sammy

We’re glad you like it! Let us know if there’s anything else we can help you with

Best,

Margarette

All ofnthe ebooks you provide are wonderful. I do have one suggestion. Can you make an ebook that includes important little tips and or strategies about particular topics? I know it sounds complicated, but from all the notes I have taken, I can explain more, again this is just a suggestion. Kind of like little things may not know that are vital to each property. Thanks so much.

Hi, Craig

Do you mean for concepts (ex: Geometry) or for question types (ex: Quantitative Comparison)? The Magoosh lesson videos are great for that, and you can always send us any questions about anything you find unclear. Let me know if I’ve misunderstood your suggestions!

Best,

Margarette

Kind of like knowing for example in a qc, mc, all that apply, etc, how can algebra, geometry, nmber property questions be asked?

Ah, I understand. That would be pretty tough, since each question can have a blend of concepts, with many, many combinations thereof. The best thing to do would be to try a lot of practice questions until you get a better feel for how to tell, at a glance, which concepts you need to know in order to answer it correctly.

I hope that makes sense! Let us know if you have any other questions or suggestions

Yea I am writing down that qc questions don’t ask must be statements. Knowing whether certain strategies always work in different question types, etc.

U guys should make an ebook on the math question area itself. Like the types of questions and the strategies for each

Aha, that I can help with! Check out the Math section in the General eBook: http://magoosh.com/gre/gre-ebook

In the topic “Factorization” on page 10, paragraph 2, the GCF is typed instead of LCM. The GCF of 4 and 6 is 2 not 12, I think.

Hi, Dheeraj

Yes, that’s a typo, thanks for catching it! It’s been fixed :).

Best,

Margarette

your efforts are laudatory. Deserving a paeon for sure.

Thanks, Abhay! Chris would definitely approve of you actively using those GRE words!

paean (just keeping you on your toes)

I see 81 Practice questions left to be attempted on my dashboard though i completed all the questions one week back. Are they new? :). If it is new content, then it is awesome.. Am absolutely loving the content.

Hi, Dinesh

Yep, we just added a new batch of Sentence Equivalence questions! 😀

Best,

Margarette
