I've got a question on the Arithmetic to Memorize flashcards.

Is it really recommended to memorize all the multiples of 8 to 160, the multiples of 12, to 120, the multiples of 15, to 150, the powers' of 2 up to 2^7, and the powers of 4 up to 4^4 and 3 up to 3^5?

Or should I just be able to calculate these values quickly. I know this is in excess of what the MGAT books recommend.

Looking for opinions before I dedicate the mental capital to memorize all theses.

I would not recommend that. Do not try to burden yourself with memorizing too many things.
As long as you are able to calculate these values quickly, you are good to goo.

Hello bb,

The link is not valid, maybe, as I tried downloading the flashcards several times but could not. Could you please check at your end the validity of link and fix it, if required? Thanks.

Regards,
Pallavi

same here,
In statement 1 m>n no matter we plug in m=2, n=1 or m=3, n=2. RHS>LHS. How did you conclude that statement 1 is insufficient ?
Also I'm having trouble understanding statement2, Can someone kindly decipher it.

Thanks in advance

I loved thanks
I think the card triangles 8 ( ultra hard) should use greater than 1 instead less than 1.

It is a great question which Bunuel solved.
Since I am new, I cannot post the link to the old thread ( ds-triangle-m09q07-72173 )

Shooting for perfection :)

P.S. Thank you to Dreamy for help as well.


thanks so much. I am having trouble with understanding the method in slide 62, the one with the advanced method for finding the number of all possible
factors. can you explain it please? thanks!!

You may get better luck/success if you actually paste the contents or take a screenshot if it has formulas/other items that you can't easily copy.

yes of course, thank you.

 Advanced method for finding the number of all possible
factors:
 Write out each prime factor and their power, for
example, 12 can be written as follows:
 2^2
 3^1
 5^0 etc (all other primes will have a zero power)
 Add 1 to all powers and multiply them: (in this case 6)
and that’s the number of factors (1, 2, 3, 4, 6, 12)
 Prime Factors of 462 = 2^1, 3^1, 7^1, 11^1
 Total number of factors: 2x2x2x2 = 2^4= 16
   1   2   3   4   5   6   7   8   9   10   11
