THIS MONTH'S WINNERS:

    Tim Berry, nimbus@shell.portal.com,

    and Pat Larkin, of Louisville, Kentucky!

Recently my email account was suspended for my yearly renewal, which is
required every year at the end of August. I have had one winner who also
changed mailing address, so if there are any other persons who were
announced winners publically or privately please contact me with your new
address (there are 2 of you!).


THE PUZZLE:

There are two matrices, A and B. Each matrix will have a
value applied to it, and you must determine the answer. The
value is specified by x, and the answers you must provide are
Ax = ?, and Bx = ?.

x = (151647 - 61615)

    [ 7 8 9 ]       [ 1 2 3 ]
A = [ 4 5 6 ]   B = [ 4 5 6 ]
    [ 1 2 3 ]       [ 7 8 9 ]
    [ 0 0 0 ]       [ 0 0 0 ]

What does Ax equal, and what does Bx get you? Also provide
your method of obtaining the answer. I understand that there
may be cultural differences for this problem... not all math is
the same (you should see how my mother does long division!). So
just make a good guess ::heh heh::. With a little research, you
can determine the answers. You may want to look for information
on matrix multiplication.
As a special bonus, the first person to successfully supply the
correct answer will automatically win. If you feel that you
definitely have the answer, get in touch with me with what you have
learned. If you do everything correctly, I will answer to let
you know :).

As an additional clue, the x value has a special code in it that has
to do with area.


THE WRONG ANSWERS:

Anything that assigned A, B, or x to a numerical value is considered
a wrong answer.


THE WINNING ANSWER:

Pat Larkin of Lousiville Kentucky was the first to answer the
problem correctly in the manner described.


THE BREAKDOWN:

There are two matrices, A and B. Each matrix will have a
value applied to it, and you must determine the answer. The
value is specified by x, and the answers you must provide are
Ax = ?, and Bx = ?.

x = (151647 - 61615)

    Notice the value of x... it is not meant to be performed as an
operation. In fact, the two numbers are part of a hidden code. If you
take those two numbers and write them a little differently, such as:

    1516 - 4761615, or 1516 - 476 - 1615, or 1 - 516 - 476 - 1615,
you might figure out exactly what it was. :) The number is in fact a
phone number, and mine at that!

    [ 7 8 9 ]       [ 1 2 3 ]
A = [ 4 5 6 ]   B = [ 4 5 6 ]
    [ 1 2 3 ]       [ 7 8 9 ]
    [ 0 0 0 ]       [ 0 0 0 ]

    Matrix A is the layout of a calculator or the numeric keypad on
a keyboard. Matrix B is the layout of a telephone keypad.

What does Ax equal, and what does Bx get you? Also provide

    Ax gets you some numeric operation, while Bx gets you *ME*, since
it was my phone number provided.

your method of obtaining the answer. I understand that there
may be cultural differences for this problem... not all math is
the same (you should see how my mother does long division!). So

    Actually I wanted to say that not all phone service is the same,
and that is the cultural difference I really meant.

on matrix multiplication.

correct answer will automatically win. If you feel that you

    After the last issue that the puzzle was posted in, I received
a phone call from a member of CompuServe with the correct answer.

definitely have the answer, get in touch with me with what you have
learned. If you do everything correctly, I will answer to let
you know :).

    When he called, he got in touch with me, and I answered the phone. :)

As an additional clue, the x value has a special code in it that has
to do with area.

    The x value contained my area code.


    If you read my PhonePak review, you would have seen this paragraph:

The number of extensions is almost limitless. Each one has its own
extension number and parent mail box. You could also design extension
based upon employee names. I like to use my area code (516) as an
extension because it helps people remember it when they call. Also,

    Here I gave the number 516 so that people would see my area code,
although my phone number is also listed elsewhere in Amiga Report.

I could program it to use the initials of our employees or their first
names. For example, using the initials of Bob xanth, a person would
hit 29 on the phone keypad. Most words are hard to spell out using
numbers, but it can be done. I have too many 0's in my office phone
number, so I can't make up a sensible word. My grandmother though
has a good one; her number (different area code though) spells out
NAB-FOOD, which is what I usually do when I visit her. :) But of
course she doesn't have a clue on how computers and codes work
(apparantly like most of our contest readers... heh). :)

    And the last line was a hint mentioning our monthly contest,
which was discussing at this particular time about using the PhonePak's
dial extensions, and tricks using phone keypads. :)

    In my review of graphicRECALL, I made the following statements:

Maybe I can convince him to donate a copy for the Amiga Report
contest, and give one of our readers a chance to win another unique
package, but I won't know for sure until I pick up the phone and call him.
I'll clue you in on what happens, in one way or another. :)

    And there is the clue, picking up the phone and calling.

    From my review of the EGS Spectrum board, I allude to the calculator
keypad:

EGS also includes some tools, such as a nice screenblanker and a calculator
program that draws algebraic functions in 3D. I just had to mention it for
those of you who are into sine waves, matrices, etc. Eh? :)


THE DISCLAIMER:

DISCLAIMER: This contest is being provided as a service to the
Amiga community and all persons involved in running this contest
cannot be held liable for anything that costs you money or
lifetime pain and anguish. Rules are subject to change. All entries
must be received by the posted deadline. Any entries beyond this date
will be entered into the next contest, if any.


THE APOLOGY:

Sorry that they were so hard, and that a few issues of AmigaReport did
not make it out due to computer and network failures (phone company)!
But the phone company will be able to make up for it in the current
contest. :)

As Edward Cayce might say, that is all for the present...
