      When I was young, I memorized a bunch of useless stuff like that and now my memory is obese and sluggish due to early abuse. It's not like exercising a muscle, it's like an eating disorder. You don't have to believe me. You'll find out on your own. By then I won't be able to say "I told you so" so I'm saying it now.

      I always try to develop a real intuition for everything in my engineering courses.
      I don't like using formulas and handbooks, I feel much more flexible when I can actually derive things from scratch. =P
      In fact, I recently spent several hours making sure that I could derive all the formulas for central-force motion, and then reviewed them once a day for a couple weeks until it really had stuck.
      Now I can derive periapsides, apoapsides, distances, velocities and eccentricities without having to look up a damn thing. :D

      This. This one-thousand times. This is the exact problem I had all throughout school. Every single teacher I had threw formulae at me, told me to remember them, and made no effort to explain their derivatives. May as well have made random numbers up and said they were important. It wasn't until a few years ago that I had to start tracking inventories that I ended up having to (reluctantly at first) relearn basic maths, as there came a point where I didn't know the operations I wanted Excel to do. Best decision I've ever made. Not that I'm particularly far along, mind you - but, figuring out how the different branches fit together, how they came to be, and more importantly WHY these things are true is fascinating, and quickly became something I was utterly obsessed with.
      I might also add that, with an intuitive understanding of the rules and why things function the way they do, there are indeed the real-life applications that people so often spout about, even if they themselves couldn't have given you a single example.

    "If you wanna cheat, it's really quite straightforward. You put aside a month or two just to memorize this, and you can cheat with this inside your brain. That's the great thing about the human brain: you can cheat by memorizing your cheat notes, and then you can look at them without anyone being able to tell. It's a real loophole in life--you can cheat by memorizing." -Parker 2k17

      Hmm.... i might have underestimated the problem a little bit. I have to make the script place all kinds of operators in an expression and then make it evaluate it, which is a bit more difficult than I thought. Plus, I have to tell the script to put brackets in all types of places... I've given up on it for now, however I might get back on it soon.

    • @lucbourhis3142
      @lucbourhis3142 7 років тому +3

      Obvious tip: abstract! Expression tree… Similar method as used to find solutions for the infamous game "Countdown"

    •  7 років тому +5

      Ok, here are my findings so far:
      You can have the following different operators: +;-;*;/;_ (nothing, just chaining the digits to a bigger number);*- (multiply with the negative) and /- (divide by the negative). +- is just - and -- is just +. On 8 positions, that's 7^8=5.764.801 combinations, which should be pretty straightforward to implement (_ before * / *- /- before + -). Also the 1 can be negative, which doubles this.
      Now to the brackets, which are the really difficult part about this: You could try to optimize it and put in all the rules so that you get all different possibilities, but only the necessary variants. But that's extremely difficult, because you could for example have multiple opening and/or closing brackets between two numbers, you can have a closing bracket, an operator and an opening bracket, but that not if the operator is _, because obviously you can't put two digits together to one number, but have it split with brackets. That would just be multiplication, we don't want that. Also you would want to exclude things like (1) or ((1+2)). And the more you think about it, the more can go wrong. So don't restrict the position of brackets too much. But what can you restrict? The total amount. In the worst case you might get something like 1-(2-(3-(4-(5-(6-(7-(8-9))))))), which are 7 pairs of brackets, but you can shorten that to 1-2+3-4+5-6+7-8+9. And I haven't found any combination yet that needs more than 4 brackets. So that's pretty reasonable. You can start a bracket from [before the 1] to [between 7 and 8] and end it after at least two numbers. So depending on how much effort you want to put into reducing the number of possibilities further, you can spend different amounts of time with that or let the computer do it. You could just (or I could, I want to do it, too) let the computer place four starting brackets at the 7 different positions and the ending brackets at the end positions >=2 after the opening one. That way you would also have the brackets linked and never have too many early closing brackets. And invalid cases like )_( it could just skip, there shouldn't be too many of those.
      All that's left now is to program the actual operator evaluation, which should be a fun programming challenge unrelated to math(s). The limited amount of brackets should allow you to rearrange it as you need it before actually evaluating it. Maybe give every digit group a priority index? I don't know, I haven't thought about that too much yet.
      I'm pretty sure that the brackets will make the number of possible combinations insanely high, so it might need some more optimizations to run in a reasonable time. I would keep my PC on for a week if that's definitely necessary, but I wouldn't want a full month. So if it takes too long, I would have to optimize further.

    •  7 років тому +1

      But... If the computer already runs that long... Why not save ALL the results and sort them? Then you have a complete index! It's a limited amount of possibilities anyway, you can't go to 10 or 11 (or A or B), because it's all base 10 based and the length is also limited. So we can make a complete table, not just a small one that this quoted person (whose name I forgot) made!

      If it doesn't enhance your life, it's not a life hack. Just more useless "knowledge" you get a ton of in "education".
      This is so bored and tired, it isn't even a fun fact, because it isn't fun. Just typical math nerds thinking they're super smart about something that won't help you or anyone else for that matter.

    I'm thinking the 10958 problem could maybe be feasibly brute forced. The numbers stay the same it's basically just the mathematical instructions and brackets that are different and change the result. I can't imagine it being too difficult for a computer to calculate a list of all of the possibilities.

    • @gyurhanaziz7676
      @gyurhanaziz7676 Рік тому

      Technically yes. The possibilities are around 4⁸ but if we need brackets things can get out of hand quickly.

    • @liammartinsmith1
      @liammartinsmith1 5 років тому +13

      The actual information is likely 99% useless as it's pretty abstract. But if the Indian dude has come up with a method for verifying that his calculations are the shortest possible root to get an answer and with just the resources available each time, that likely has some very useful applications in computing or quantum mechanics or something similar if it can be made into an algorithm in A.I. Sometimes we don't always have a full set of tools to do something or we don't use our tools in the most efficient way. This guy likely does a lot of useful maths too and this little party trick could be an offshoot of something massive he has worked on and solved. Peniscillin was an accidental discovery that came from just dicking about carelessly though so even not having a purpose in the outset can be amazingly useful in the end.

    Not sure if this is an acceptable solution due to the presence of a somewhat spurious 0th power on the eight term, but here goes anyway: [(1+2)^(3+4)]*5 + 6 + 7 + 8^0 + 9.
    I guess it might be considered a near miss. If the rules regarding concatenation etc, were spelled out to us more clearly, then we might have a chance at a valid solution.
