    Re: Grid maths

    Are you sure of all your items. I do not get initegers for all of A-H

    B is the last digit of pi to 8 decimals <span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">(3.14159265)</span hide>
    C is <span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">25 = 12 +13</span hide>
    D is then: <span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">42/30 = 1.4</span hide>
    FIfth Catalan number <span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">42</span hide>
    divided by B+C = <span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">5+25 = 30</span hide>

    Re: Grid maths

    Since I am having trouble with several, could you point me in the right directions:
    What am I missing or where have I gone wrong? <img src=/S/confused.gif border=0 alt=confused width=15 height=20>

    The last digit at the end of pi to 8 decimal places (not rounded)<span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">5</span hide>
    The only square that is the sum of two consecutive numbers?<span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">25=12+13</span hide>
    Fifth Catalan Number<span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">42</span hide>
    Sixth Fibonacci number<span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">8</span hide>
    Third Lucas Number<span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">4</span hide>
    The number of ways of coloring the faces of a cube with three different colors.<span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">729 = 3^6</span hide>
    The third untouchable number<span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">52</span hide>

    Hi Steve

    <span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold"> I think you may have made a mistake calculating C (remember A,B, etc must be the values of 1 to 9 to fit into my grid) C should be

    x^3 + (x+1)^3 = C
    </span hide>

    Re: Grid maths

    You said that C is "The only square that is the sum of two consecutive numbers" This is <span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">25 = 12+13</span hide>. What is there to calculate?

    If <span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">25</span hide> is not correct, then there must be another square that meets this criteria...

    Re: Grid maths

    For the "The number of ways of coloring the faces of a cube with three different colors"
    <img src=/S/blush.gif border=0 alt=blush width=15 height=15><span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold"> I forgot the spatial aspect: that faces can move in space. Is 55 more what you are after? or do you have conditions on it like no 2 touching faces may be the same color or I must use all the colors? </span hide>

    Re: Grid maths

    Do you mean a CUBE not a SQUARE?

    Re: Grid maths

    Sorry Steve

    I checked and double checked my graphic and now I realise I made a mistake <img src=/S/blush.gif border=0 alt=blush width=15 height=15>

    C should read "The only square that is the sum of two consecutive cubes"

    I have changed the graphic

    Yours grovelling

    Re: Grid maths

    No it doesn't .

    I have A-E to be integers, but can not get G to be an integer and F and H depend on G..., but even just putting in values from 1-9 in in G does not get the F/H to be integers.

    I have:
    A-E as <span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">3,5,9,3,2</span hide> but I assume I am off on one of them or I wouldn't be having problems.. <img src=/S/hairout.gif border=0 alt=hairout width=31 height=23>

    I guess I will take a break and do some of the chores my wife is screaming at me about... <img src=/S/smile.gif border=0 alt=smile width=15 height=15>

    Re: Grid maths

    I think there is another error in the value for A. The result for this appears to be <span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">3</span hide>, but subsequent results only work if the actual answer for A is <span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">5</span hide>

    Based on that I have a possible answer of <span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">1452 - Leonardo Da Vinci</span hide>

    Re: Grid maths

    Why didn't I just work on trying to get them all to be integers... I should have just used the solver in the first place

    I kept trying to solve the puzzles along the way....

    Did you actually get A to calc as <span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">5</span hide> or did you just try values? If you got 5, what were the values of C,D,E?

    Re: Grid maths

    The values I got were <span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">C=9, D=3 & E=2</span hide> this give a value for A of <span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">3</span hide> but the answers for G & H only work if A=<span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">5</span hide>

    Grid maths

    I have created a 9 by 9 grid. This grid contains a set of numbers. The red numbers ( or smaller numbers to the left and base of the grid) are grid reference numbers.

    I have set a series of questions that you are required to answer so that you will identify and note 4 grid references.The grid references are in this format:

    (A , [img]/forums/images/smilies/cool.gif[/img] = w
    (C , D) = x
    (E , F) = y
    (G , H) = z

    w , x , y ,z equal the values found in those grid references

    Your job is to answer the questions below the grid, identify the the co-ordinates and find the values of w,x,y and z.

    Now put w,x,y and z together ( wxyz) to create a 4 figure number. This number is now a year.

    Can you tell me the name of the very famous person who was born in this year? ( I will allow alternatives here as long as you can prove they were born in wxyz)

    Steve

    Now I am REALLY embarrassed. Please except my apologies there should have been a +2 after the equation got A.

    This really has taught me not to create Woody puzzles at 12.30 in the morning. If you do this the rest should work themselves out. I have changed the graphic to reflect this.
