  > Go down
  You make your way down.
  
  Off to the side sits a gray storage bin. In the storage bin you see a square piece of metal and a scribbled scroll.
  
  A gray, translucent ghost flits around the storage bin.
  
  > Inventory
  You are carrying:
  a square root
  a negative sine wave
  a set (no longer empty)
  a slide rule
  a cube
  some exhaustion sandals
  a tetrahedron
  an octahedron
  an old coin
  your math book
  
  > Go south
  You make your way south. As you do, you feel an electrical impulse course through you. You find yourself in...
  
  A part of the wall has slid open, revealing a niche.
  
  There is a strange mechanism in the center of the office.
  
  You can also see a parchment here.
  
  > put the wave in the panel
  You carefully insert the negative sine wave back into the strange mechanism.
  
  > turn the crank
  You turn the crank, which causes the two small gears to rotate around the large gear. As the small gears rotate, they move the metal bar back and forth in a straight line.
  
  Then the strange mechanism emits an aura of negative power that fills the room. You briefly feel more depressed, as well as more pessimistic about your chances on tomorrow's exam.
  
  For just a moment, the square root glows, as it absorbs the negative power emitted by the mechanism.
  
  > look at the root
  This is an unusual object. It appears to be made of some tough vegetable matter - perhaps the root of a tree. It's also in the shape of a perfect square. The word "EXTRACT" is written on it.
  
  The square root has also absorbed negative power from the machine in the physician's office.
  
  > Go north
  As you move north, you feel an electrical impulse course through you. The space around you seems to fold in on itself.
  
  Off to the side sits a gray storage bin. In the storage bin you see a square piece of metal and a scribbled scroll.
  
  A gray, translucent ghost flits around the storage bin.
  
  > Go upwards
  You can see absolutely nothing in the blue darkness off the number line. Stepping off it doesn't sound like a good idea.
  
  > Go east
  Number Line: 2
  
  > Extract root
  The root vibrates quietly, as it extracts the square root of the essence of the space around it. You feel yourself shift.
  
  Irrational: Between 1 and 2
  This is more of an abstract space than a physical place, but it feels large beyond your understanding, as if it encompasses infinitely more space than the single-number locations beneath the number line. A hole leads up to the number line.
  
  > Go up
  You make your way up.
  
  As you step onto the number line, the hole behind you closes. Rather than standing at an unmarked spot between 1 and 2, you head back to 1.
  
  Number Line: 1
  
  > go west
  Number Line: 0
  
  > go west
  Number Line: -1
  
  > Extract root
  The root vibrates quietly, as it extracts the square root of the essence of the space around it. You feel yourself rotate
  clockwise, swinging in an arc that takes you halfway back to the positive part of the number line.
  
  This is more of an abstract space than a physical place. It feels different than the spaces just below the number line - not less real, but more as if this space exists in a different dimension. A hole leads up, maybe to the number line?
  
  > Go upwards
  You make your way up.
  
  As you climb through the hole, at first it appears as if you are climbing into a dark blue nothingness. But then a thin, infinitely long vertical line appears out of that nothingness, widens, and rotates 90 degrees to run north-to-south. You confidently step onto the new line.
  
  Imaginary Axis: i
  You are in a dark blue expanse of space, standing on a white line that stretches as far as you can see to the north. To the south you can perceive where the imaginary axis crosses the number line. The number i is marked on the line here. There is a hole next to the
  i that you might be able to climb down into.

  > go east
  Real Axis: 1
  
  > go to the north
  You make your way north. As you do, you feel an electrical impulse course through you. You find yourself in...
  
  Someone has left their trigonometry homework on the log table.
  
  On the grass lies a funny-looking soccer ball.
  
  > examine the homework
  The homework is covered with equations involving sines, cosines, and tangents. There are also a couple of graphs drawn on the homework, labeled "sin x" and "cos x." Each graph consists of
  a wavy line that switches from positive to negative every Pi units. Circled at the top of the homework is the phrase "Review Logarithms!!!"
  
  > kick it
  The soccer ball remains still, and your foot connects with a solid "thud." As the ball flies through the air it begins to transform, becoming less round and more pointed. It bounces off one of the buildings and rolls across the grass, coming to a stop near you. You look down to see an object that is no longer quite a soccer ball.
  
  > look at it
  The icosahedron has twenty sides, each of which is in the shape of an equilateral triangle. It kind of looks like a more pointy version of a soccer ball. In fact, you realize that if you cut its vertices off in the right way and inflated it to make it more round you would have a soccer ball. This icosahedron is about one cubic foot in volume.
  
  > get it
  You take the icosahedron. Looking curiously at it, you note that it has twenty sides, each of which is in the shape of an equilateral triangle. You feel you understand three-dimensional solid geometry a little better.
  
  [Your understanding of Geometry has increased. You estimate
  that your score on tomorrow's final has just gone up by one

  > look in the dryer
  The dryer is empty.
  
  > look in the washer
  The washing machine is empty.
