Chess and Math

Thanks, you made me feel better with that comment.

I'm happy to be able to offer encouragement.  What I wrote before was what I would tell my younger self if I could go in back in time.  Many people learn things the hard way; wise ones learn from others' expereinces too.  One thing that really helped me break out of gloomy periods was reading the autobiographies of my heroes.  Learning about the struggles of others can help you find inner strength.  Wishing you great success! 

yes u r true.

Practical Co-ordination and move distance:

The Set of all Squares in Board, S = { a1,a2,a3,....h8}

In co-ordination

       { (1,1)(2,1)(3,1)(4,1)(5,1)(6,1)(7,1)(8,1)
         (1,2)(2,2)(3,2)(4,2)(5,2)(6,2)(7,2)(8,2)
         (1,3)(2,3)(3,3)(4,3)(5,3)(6,3)(7,3)(8,3)
         (1,4)(2,4)(3,4)(4,4)(5,4)(6,4)(7,4)(8,4)
         (1,5)(2,5)(3,5)(4,5)(5,5)(6,5)(7,5)(8,5)
         (1,6)(2,6)(3,6)(4,6)(5,6)(6,6)(7,6)(8,6)
         (1,7)(2,7)(3,7)(4,7)(5,7)(6,7)(7,7)(8,7)
         (1,8)(2,8)(3,8)(4,8)(5,8)(6,8)(7,8)(8,8) }

In this System , it is very difficult to do calculation for single  move.
Many many equations will arise and it is nothing but  time waste.

To solve this problem- there new co-ordination system:

      { 11 21 31 41 51 61 71 81
        12 22 32 42 52 62 72 82
        13 23 33 43 53 63 73 83
        14 24 34 44 54 64 74 84
        15 25 35 45 55 65 75 85
        16 26 36 46 56 66 76 86
        17 27 37 47 57 67 77 87
        18 28 38 48 58 68 78 88 }

Suppose , there is Nd4 = N(4,4)= N(44) [actually it is equivalent not equal]

[ "x" for grab a square, "x" for  holding squares]

So,
 (N x 44) x { 23, 32, 56, 65, 36, 52, 63, 25 }

differences from centre 44 are [8,12,19,21,-8,-12,-19,-21]

      [ 44-23= 21
         44-32= 12
         44-56= - 12
         44-65= - 21
         44-52= -8
          44-63=-19
          44-25= 19]

For diagonal distance =[ 9,11,-9,-11]

For vertical distance = [1,-1]
For horizontal distance = [10,-10]

Test it you will find the same results.

you can not understand it with your shallow thinking. There are practical needs.In mate calculation i 've faced  several problems and finally to solve problem i came into this conclusion.

Stupid, do not think that people are silly like you .  Read my earlier post and you will find whether i do understand or not. Actually you tried to make me outraged. Troll, Get out of here. If do not like it, leave it. You are  lack of intellectual ability. I pardon you , naughty boy.

Be nice, gentle and civilized. Get smarter. Do not be rubbish.
Did not your parents teach you anything good?

People like me replied  your answer, is not it enough for you?

Do not act like pauper and poor. I can buy you like products for one time use.

the words of a spoilt child.

Has anyone here learned calculus yet?  Because I need help, I'm already almost into 7th grade, and I haven't learned it yet!Please help me!

But I already know Algebras I & II and am well on my way in pre-calculus!

i was in barnes & noble a couple of weeks ago and came across a book called "all you need to know you learned in kindergarten".

It's actually true

You're wrong.  I'm in the Takoma Park magnet and also do lots and lots of extra-curriculars both alone and with my dad, with whom math is an integral part of his job as an economist.

but your dad is a smart guy isn't he?

As I recall, Newton developed The Calculus to solve a problem of the net gravitational attraction on a point-mass inside of a hollow, homogeneous sphere.

The answer was, that the gravitational attraction was null, and the point-mass was "weightless."

Yes, my dad's a smart guy.  I'm reviewing geometry with help from him.

then any math he needs don't you think he can learn on the job?

let me speak to him

Please ignore GreedyPawnEater's attempts to discourage you.  All of his posts that I've seen are full of negativity and bitterness.  Don't let naysayers sidetrack you from your ambitions.  There is nothing to stop a motivated 7th grader from learning algebra, calculus, and even more.

No by all means do what you enjoy! We say yes here! but just understand because you guys are smart, technically, you can learn it at any time....... 

Good, keep it up!

My son got his degrees (BS and MS) in engineering and started at nearly $100,000 per year, right out of college.

And just instead of spending a voluntary hour on the math perhaps he can try something new.... makes life more interesting
