You must be confused by the title. I was quite confused myself before I typed it, while I typed it, and am still confused, after typing it. I just related this story to a member of the janitorial staff here at Weber State University, and he was also confused. I’m still confused, but I understand how I got to this point. Seeing as my only understanding of this curious situation is enlightening, though limited, I feel a responsibility to relate my understanding of how I came to this point in my mathematics career to you, so as to relieve a small bit of your confusion also. After all, it is I who dragged you into this mess in the first place.
I was hungry. Not hungry for a big satisfying nutritious meal, but also not hungry for just a bite from a friends’ dinner. I was somewhere in between. My stomach was not quite growling, but I felt the need for a small amount of sustenance. I decided a snack would both bed down my appetite before it grew to dizzy spell proportions, and allow it to rise again just in time to enjoy a full meal once I got home. My mind immediately scanned its memory banks for locations of food sources in my immediate area. Vending machine. A quick exchange between robot and mankind would immediately produce both the quantity and quality of confection I was looking for. Or so I thought.
This is the twist.
Upon approaching the large square and cavernous quadruped monument to technology and preservatives, I noticed the line of yellow bags which contained chocolate and candy covered peanuts (or ‘flavored candy coated chocolate pan disks’ as the folks at the Wornick Co. classify them). Upon closer inspection, I learned the machine required eighty-five cents from me in order to render the small bag of goodies into the receptacle labeled ‘PUSH’. My human mind in its infinite processing and memory access power decided to insert a dollar and get some peanut M&Ms.
For the rest of this story, I will present each action in order, as it happened, for the sake of continuity. It’s hard to understand how each event fits with the other; and how these events, when strung together, produce the formula which is the title of this story. No need to thank me just yet.
1. I insert a one dollar bill into the slot labeled ‘INSERT BILL HERE’
2. I punch in the number which corresponds to my preferred junk food; 53
3. A red LED light illuminates next to the phrase ‘Use correct change’
4. Confused, my mind retraces my actions, and decides I made a mistake somewhere
5. I punch in the number 53, taking extra care to enter the number correctly
6. A red LED light illuminates next to the phrase ‘Use correct change’
7. I notice the ‘CREDIT’ display indicates two dollars
8. My mind retraces the events of the past few days, weeks, then months, looking for signs that I’ve journeyed to some parallel dimension where the laws of logic and physics are radically different
9. I assume the machine is out of correct change, and that instead of overcharging me, it is more content to keep the two dollars to use for whatever it sees fit; be it Presidential campaign contributions or the purchase of stale baseball card bubblegum on ebay
10. Referring back to step 8, I assure myself it is not the case that I am on an alien planet or in an alternate dimension
11. Assuming I now have two dollars in credit, I consider alternative selections
12. I realize the inferiority of all other snacks presented to me
13. I decide that the problem is that the machine has no coins to dispense for change
14. After doing some math, I figure .85 time 3 is 2.55, therefore, if I give this robot another fifty-five cents, it will then give me three bags of candy, providing I input the correct number on three consecutive events
15. I insert fifty-five cents with a feeling of satisfaction and an heir of intelligence
16. A red LED light illuminates next to the phrase ‘Make another selection’
17. I abandon all reason, and enter the number fourty-two, seeing as it is the answer to the greatest question of all time; according to Douglas Adams
At this point, the most astonishing thing happens. The machine dispenses a pack of three Reese’s peanut butter cups. I take inventory of the situation and decide one dollar and fifty-five cents for three peanut butter cups is not the worst thing in the world. As I sit and eat the three delicious disks I ask myself some questions. What does this mean? Are robots everywhere becoming self-aware, and making decisions for us? What’s the significance of the number 42? Was this plotted out long ago by some genius mastermind who has been captured by the manufacturers of the vending machine, confined in a basement by his captors, and made to write programs for their machines to produce random events such as this in an effort to make people anxious so they will one day rise out of angst and topple the government so they can step in and rule the world? What does it MEAN?
And that is how I got to this point. 1.00 + 1.00 + .55 = 1.25, which is the price of three peanut butter cups. I don’t understand the logic behind it. Perhaps if I had the processing and memory retrieval power of a vending machine I could. But alas, I am merely human.
