The CD has tiny dots on it that are changed by the laser to be a digital 1 or 0. The CD drive then used the reflected light from the disk to recreate the 1 or 0. The math you could use would relate the amount of dots (bits) knowing that 700Mb disks have 7,000,000 bytes of info and a byte is 8 bits, you would come out with 56,000,000 dots on the disk.

Well, I agree with Rosie. You can do proofs really fast if you have a very clear understanding of all the required theorems & formulae. But for this you need to really really practice - and the time won't be far away when the only time that will be required will be the time you take to write the proof! I was very poor in this subject - but I was so determined that I would sit long hours and try to prove it on my own. Believe it or not I would spent 2 or 3 hours for trying to prove certain problems  i.e without taking anybody's help. It was very tough initially - sometimes i was not able to do it - i would go to sleep at night with the problem in mind - honestly i would always get it right the next morning. With gradual practice i could do it in a jiffy! But my dear don't forget H.W.Longfellow - "The heights of great men reached and kept, Were not obtained by sudden flight, But they, while their companions slept Were toiling upward in the night."

b-a, at least if it is mathematics

Can I have a clue please?

read lots of books (or a dictionary), do well on math section, hence talk with your math teachers and ask for additional help. and yes there were a few people that did... friends of mine in fact...

PRACTICE PRACTICE PRACTICE. I am a math expert and that is the way i developed a very quick mental math capability.

Well hey, you need help, ask the teacher! I know how to do this, with help from my nerdy Calculus BC friend, but it's really not that hard once you think about it...

haha, thats crazy to ask.\n\nbasically, this was proven by andrew wiles in 1994, and resubmitted after an error was found\n\nhe developed new mathematics that will basically be the foundation of study in the coming century.\n\nthe level of mathematics that would be required to understand the proof most PhD mathematicians dont have.\n\nsorry\nwish i could be more help\nmatttlocke

Some useful things to learn for quantitative aptitude, especially for division and factoring:\n1) perfect squares up to 20^2\n2) perfect cubes up to 10^3\n3) multiples of 12, 13, 15, 16 (up to 20)\n4) divisibility tests (quick ways to determine if a number is divisible by another number)\n\nFor the last, I found the website below to be the most complete.

Can answer if I understand.

learn lots of tricks.  They help you to do computations faster.  \n\nFor eg., like this question:\n\n379x231+391x1269\n\nYou would probably go, OMG, this is impossible.  \n\nBut if you take the 391 out from both sides you get \n\n391(231+1269)\n\nwhich = 391x1500\n\nSuddenly it's not so hard.  \n\nHere are some good sites:\n\nhttp://www.angelfire.com/me/marmalade/mathtips.html\n\nhttp://www.curiousmath.com/\n\n\nGood Luck!

There are several simple rules for re-arranging and solving equations.  It would be in your best interest to try and learn them, they aren't very hard.

Yes, many people do know how to solve that problem.  They learned it the same you should: read your book, go to class, talk to TAs, and do your own homework.

All inability stems from not understanding words, symbols etc (the misunderstood word or symbol). So in knowing that data, I presume that many people have a lot of words and symbols in the subject of maths that they do not fully understand.\n\nTo improve your maths skills, get some good dictionaries and look up EVERY word and symbol that you do not fully understand that you come across...you will be AMAZED at how much your ability will increase!

talk to your math teachers, ask them what you don't understand so you can understand everything. so when they introduce a new concept, you can figure it out from prior knowledge.
