Unravel the meaning of the variables to find numerical answers

  1. Feb 7, 2009 #1
    This is a riddle that has proven to be a stumper.
    At least, the people I have asked...

    The task is to unravel the meaning of the variables to find numerical answers.
    Can you do it?

    Solve for "s", "t", "r", and "u:" *Edit* When Zero is not a solution. *Edit*

    [tex]
    s * s & = & & s \\
    [/tex]

    [tex]
    s * t & = & & t \\
    [/tex]

    [tex]
    t * r & = & & u \\
    [/tex]

    [tex]
    u * u & = & & t \\
    [/tex]

    [tex]
    u * r & = & & s \\
    [/tex]

    [tex]
    r * r & = & & t \\
    [/tex]

    s=0
    t=0
    u=0
    r=0

    Ah, yes, this is true; but not exactly as complicated as it truly is.

    I say this, and I should have said this before, because none of these values equal zero.

    And! No values "repeat" themselves, exactly.

    Try again

    Re: Riddle-d'Do

    s=1
    t=1
    u=1
    r=1

    Or is that what you mean by "No values repeat themselves, exactly."

    s = 1
    t = -1
    u = i
    r = -i

    ha-Ha! Yes, that is the correct set of answers "Moo"!

    But you can also notice that i and -i can be inter-transposed and still make sense.

    Good job.

    Yea, if they are all ones then it works as well, but I thought that
    was too easy so I said that they shouldn't repeat.
