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.

You ask a good question. The answer lies in how quickly you can actually work through the examples that you listed. So, try timing yourself - if you can physically calculate all of those end results perfectly and quickly, then you probably don't need to memorize them. However, if you make mistakes or are 'slow' with that work, then memorizing that information might be helpful to your overall performance in the Quant section.

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.

On Page 24, "Powers 9" problem; I'm sorry but could someone please elaborate the answer a bit. I'm having a bit of difficulty in understanding the logic of it.

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.

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.

Thank you to Hussain15 for pointing out a huge typo I made - I have updated the PDF. 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!!
