How do math geniuses understand extremely hard math concepts so quickly?
Some years ago I was doing a penetration test for a large mobile operator's voicemail infrastructure. The test in itself took about 5 minutes from the moment I started till the moment I was able to get into the system and change the default welcome message to something of my own. I presented my findings to the local manager in charge and, surprisingly, her reaction was - "so you expect us to pay you 2000€ for 5 minutes of work?" My answer, although a bit of a cliche, was this: "You're not paying for those 5 minutes. You're paying for the amount of knowledge gathered over the years that allowed me to figure out in less than a minute what's the problem with your voicemail." As Satvik Beri perfectly described in his answer, when you spend most of your time focusing on a specific issue, whether that's math, information security, programming or anything else - you gather enough experience to start figuring out things in a snap. That doesn't make you special, nor innately talented - just a really hard worker and extremely passionate about what you do. Think about that the next time you feel cheated by a consultant who solves your problem in 5 minutes.

Very difficult math question, can you answer it?
Will give 5 stars if you explain your answer If the parent function is y=1/x describe the change in the equation y= - 1/(x-5) -10 So y equals negative 1 over x - 5, then 10 is subtracted from the whole thing. Possible answers Reflected across the x-axis, moves 5 units to the right, and 10 units up. Moves 5 units to the right and 10 units down. Reflected across the x-axis, moves 5 units to the right, and 10 units down. Reflected across the x-axis, moves 5 units to the left, and 10 units down.
Avogadro's Law Question!! If Vi/ni=Vf/nf!! I'll give 5 stars!!!?
You studied all those years doing math equations , and you can not do such simple math problems ( OK I know that here it is called chemistry , which somehow puts it in a real difficult class ) , so let us do it for you: If Vi/ni = Vf/nf then Vi = Vf*ni/nf ni = Vi*nf/ Vf Vf = Vi*nf/ ni nf = ni*Vf / Vi
Camel crossing the desert activity. Need Help. Math problem. Hard problem. Please help. Will give many poi
Most efficient way is to make trips that reduce the number of bananas by the full load camel can carry, so 1000. Pick up 1000, go 200 miles, arriving with 800. Drop 600 there, keeping the other 200 to make it back to start. Repeat this again, which leaves 600 more, or 1200 in the desert. The third trip yields 800 more (no return trip necessary), for a total of 600+600+800 = 2000 bananas, 200 miles from start. Next travel 333 and 1/3 miles with a full load of bananas. Then you arrive with 666 2/3, drop off 333 1/3 and keep the other 333 1/3 to make it back to the other bananas. The second trip will have you arriving with another 666 2/3, for a total of 1000 bananas, and where are you? you are 200+333 1/3 = 533 1/3 from start. So you still have to go 466 2/3 miles. But you are down to exactly 1000 bananas, so no return trip is necessary for this last leg, just go. You arrive with 1000 - 466 2/3 = 533 1/3 bananas left at the end. That made me hungry.
Why is math hard for most people?
There are many reasons, but they all come to one: they have developed a prejudice about themselves, due to some misunderstanding. In mathematics, if you miss one lesson, or one step in a reasoning, then, very quickly, it will look like Chinese or Hebrew (as we say). Asking the good question at the right time could change this, but not all people dare, and sometimes the teacher might not be helpful. Mathematics is extraordinarily large, there is mathematics for all taste (classic, jazzy, romantic, cool, aesthetic, mystery, etc.), and some teacher concentrate the teaching around their taste, and very much dislike different motivations, and that can lead to conflict and being stuck on some matter. Some people like concrete things, and numerical examples, and cannot proceed if this is not presented. Other get lost in the numerical examples, and understand better when things are given in a clear abstract setting. Everyone can like a part of mathematics, but can lose interest in some other part. Some get lost in math because they were not told that it requires some amount of work. Sometimes, as a teacher, I realise that the students who understand the course very quickly, get easily bored, and don’t do the work of memorisation, ignoring that many simple things can get complex when you need them to solve a new problem. The ease they have to understand becomes a handicap to solidify their knowledge and do the work of memorising, and the management of the concept, where the more slow, and less confident students, will do, by necessity, the right amount of work. So, “having a hard time understanding math” might be part of the job in mathematics, and denying this will only make things more complex in the future. Also, a teacher of mathematics might forget his own hard time to get the idea, and be impatient. Students of mathematics are often asked to accept in one hour what the original mathematicians took centuries, if not millennia, to accept, like a famous comic illustrated so well (see below). A famous example is the divergence of the harmonic series 1 + 1/2 + 1/3 + …
I am very weak in maths. How can I develop it?
I'm very weak in Maths, or I don't know whether it's something that I, myself developed over the years. From my 7th grade, I started loosing interest in Maths since my teacher wasn't that good and she only appreciated students who did well and insulted us very badly. From that year, I just gave up my hopes on Maths and considered it as a shitty subject and pretended like I didn't care when I was really really very sad on getting very low marks in Maths when I was an excellent student in the class and scored more than 91% in other subjects, Maths always bought me down when it came to ranks. I was so depressed, I started hating Maths, and it became a nightmare for me. The day before the exam, all I remember doing was crying, crying and crying. I couldn't bear the tension it gave me. It still does. I suffer from anxiety even though I'm young; and no one is allowed to put so much pressure on me because it's trouble. Whatsoever, I still have chills and I failed in this year examination and writing a retest on Monday, and this time, I just googled whether there's anything I could do to score better in Maths, and that's when I read this interesting article and found out that I'm not alone. Because this is exactly like my story. I'm weak, I always get the just-pass marks, my brother is a top-scorer who is hopefully cracking a AIIMS soon and has 95% marks in his 12th grade and all, and I left a group tuition cause I was insulted and then joined a tuition where I used to be the only student, and I'm continuing that, but the thing I failed to keep is being regular. I'm never regular to the tuition because I hate maths firstly and I'm a lazy girl who spends her weekend by watching new movies, with drinks and chips and popcorn and stuff and going out every weekend for shopping with my family or friends, or going to stay at cousin's or mom's or spending quality time with my best friends or my best-friends-cum-family my cousins..Okay! I've told too much. I hate maths. No, I hated it. Not anymore. I'm going to pretend like I love it and work hard. I've got 5 days from now, that's like huge time to cover 6 lessons and then practice extra questions and sums. Well then! Let's see how I'll score and whether the hardwork will pay off! Fingers crossed! Maths!! HERE I COME BROTHER.
