Mathman 23  





Students and parents of students should read my introduction to letterboxing before seeking the boxes. 

These clues rely n the use of matrices to encode/decode clues. Go to this page to learn how to do this on a free graphics calculator simulator or to do it by hand.  
This box is the twentythird in a series of letterboxes with mathematical clues. The boxes are intended for both regular letterboxers and my students. This box was created by my 200506 Honors Advanced Algebra students. Much like Mathman 18, this box is very winter friendly, with most of the work done indoors. Once you decode the clues, it shouldn't take more than 20 minutes outside to find the box, stamp up, and return to the car. The indoor part however, should take less than an hour as it will take some time to find the numbers you need and do the math. You may wish to do both Mathman 18 and Mathman 6 in connection with this box, and Mathman 5 is in the area as well.  
Clues:
Be sure to read through all the clues before looking for the box so you know what is expected of you.
You will need to tour around the museum to collect various bits of information to be used to decipher the clues. As you tour the museum, enjoy it, but keep your eye open for the information you need! Once you enter the West Bend Art Museum, you would turn to your left and go through the white room and into the blue hallway to start this letterbox. (However, you first need to go to the front desk to signin.) Go down the staircase on your right.
Now enter the numbers from above into the following matrix:
Add the two matrices together and decode them with the following
key: Go to the room with this item in it. Find the girl playing cards in this object. Count the number of cards that are face up: y = _____ Face the object with the courtyard in the front. Find the candle holder and count the number of candles in it: x = _____ Enter the numbers you found into the the following equation and round to the nearest whole number:
Go out of this room and turn left. When you enter the blue hallway with the bubbler on the right (watch carefully!), count that number of pictures on your left and stop there. Look at the year of the painting you stopped at. Put the third digit of the year in for y and put the first digit in for x in the following summation problem. Then evaluate the problem: Turn right and take this many paces forward. Enter the room that is directly to your right. Count the number of clocks in the room: a = _____ Find the number of light switches/knobs that are lined up in a row: b=_____ Count the number of framed pictures in the room and subtract 1: c = _____ Using the numbers you found, solve the following quadratic equation:
Once you find the answers arrange the numbers in this order (x,y,z,w). Now
find the picture in the area at the bottom of the stairs with this # in its
description. Count the number of objects in this picture. Put this number into
the following blank: 199800___a. Walk into the bluegreen room. Find the
artwork with this collection code. t = ______
Go to the entrance of the room where you first entered. Take t steps down the
hallway to your left (from the (x, y, z, w) picture). Look at the picture
to your left. Find the last digit of the year it was painted. Take this many
paces straight ahead.
Now go to the Washington County Memorial Cemetery. Go to the Mall of Drawers. The words of the decoded matrix will be found on one section of Drawers. You will find the box under the corner bush to the right (east) of this drawer. BEFORE RETRIEVING THE BOX, BE SURE NO ONE IS AROUND TO SEE YOU TAKE THE BOX
OUT! DO NOT BRING ATTENTION TO YOURSELF OR THE HIDING LOCATION OF THE BOX! Before you set out read the waiver of responsibility and disclaimer.
