NPR Sunday Puzzle (Oct 22, 2017): Two Week Challenge: Move Two Numbers

NPR Sunday Puzzle (Oct 22, 2017): Two Week Challenge: Move Two Numbers:
Q: This is a two-week challenge. Write down the equation:
65 – 43 = 21.
You'll notice that this is not correct. 65 minus 43 equals 22, not 21. The object is to move exactly two of the digits to create a correct equation. There is no trick in the puzzle's wording. In the answer, the minus and equal signs do not move.
Keep it up; you still have another week to solve this.

Edit: My hint last week was "I used to be an advocate...". I guess you could say if I'm no longer a proponent, I must be an ex-ponent. :) This week's clue is a hint to raise the numbers up.
A: 65 - 4³ = 1² --> 65 - 64 = 1

    1. And be sure to keep the 2 and the 3 full size as you are relocating them. There is no mention of shrinking in the wording of the puzzle.

      Paul McCartney wrote "When I'm Sixty-Four" when he was a quarter of the way there. He's 75 now.
      I didn't know Harry Nilsson wrote "One". Three Dog Night took it to #5 on the Hot 100 in 1969. Harry lived to be 52.

    2. Paul - I didn't know Nilsson wrote "One", either. Amazing how a lot of TDK songs were kind of springboards for some up and coming artists.

    2. Maybe it was the elves:

      "Modern spelling first recorded 1788; An Old English word for it was ælfsogoða, so called because hiccups were thought to be caused by elves. hiccough 1620s, variant of hiccup (q.v.) by mistaken association with cough. By etymological standards, both have "folk etymologies" although hiccup is the most correct."

    3. Word Woman is correct. Elves are an invasive nuisance that are the underlying cause of many of our problems. Thankfully, now that we have a strong president who will build a wall along the border and continue working to limit immigration, we should be able to get a handle on dealing with these pests. How it is that Santa is able to work with these creeps is beyond my understanding.

    8. I tend towards rye humor, but let me know when there's a rum ball in Seattle. That's whiskey business.

      Delete
    9. I don't know about a rum ball here, but I did purchase a bottle of dark rum yesterday.

      As to rye humor. Rye or Bourbon are the main ingredient in a Manhattan, my favorite cocktail, stirred, not shaken! Rye was the original, followed by Bourbon.

      After I returned from my 3 years in the Army, stationed in Germany, where I learned about life, I introduced my parents to real drinks. Manhattans were appreciated by both immediately and soon that was the only drink my mother would drink. After my father died she drank more than before, and every evening. If the family went out to a new restaurant for a big dinner and tried something new she would not even take a sip. Later I joked that the only difference between our mother and Robert Openheimer was that Oppenheimer did not have a maraschino cherry in his Manhattan Project.

      Delete
    10. Enjoyed your Manhattan story, sdb. How different does a drink taste if it is shaken vs. stirred? It doesnt seem to me it would make a huge difference.

      Delete
    11. WW - Glad you enjoyed it. I have to explain it to most these days.

      Mixology is the art of making cocktails and how to do it properly. I never attended one of these classes/schools, nor was I ever a bartender, but over fifty years ago I learned they teach that cocktails made with clear liquids are stirred, while those with opaque ingredients, such as cream, need to be shaken in order for them to mix properly. There are exceptions, such as a blended Stinger, which is brandy and colorless crème de menthe, not the green. These two clear liquids will not mix properly if stirred. If you shake a Manhattan, Martini or Negrone, etc. they will become clouded and more diluted than they should be. This will affect both the appearance and taste. The idea of a shaken Martini seems to have come about via Sean Connery in his role as James Bond. It certainly does come across as sexy when he orders his martini "shaken, not stirred. It bruised the alcohol," but this is nonsense as you cannot bruise alcohol, and if you could it would obviously be the other way around. I read once that Victor Hugo always insisted his Manhattans be stirred.

      It should also be noted that for one of the above mentioned classic cocktails to be made properly the container must be filled with a lot of ice cubes and then stirred for at least 30 seconds. I hope that helps.

      Delete
    12. Ah, I did not realize shaking drinks meant introducing ice. That does make sense, then. "Bruising" alcohol seems silly. Thanks for the explanation, sdb.

      Delete
    13. Just to give julep, no shaking or stirring if you want a "layered drink" like a B-52. I'm not much of a drinker, so I've never had one, but they look kinda cool. SDB is probably too Old Fashioned for such a thing.

      They mention you should use a metal straw for a flaming B-52, so I guess you're supposed to drink one layer at a time, mixing Kahlua, Irish Cream and Grand Marnier doesn't sound good.

  10. 65 - 4^3 = 1^2

    "Up with People" referred to the superscripts in 4^3 and 1^2.

    ReplyDelete
  11. 65 – 43 = 21, moving only the 3 and the 2 yields:

    65 – 4³ = 1² → 65 – 64 = 1

    My hint: “Roll the dice” → Dice are cubes; one of the numbers (4) needs to be cubed.

  12. Move the 3 up, and the 2 up and to the right, so the equation becomes "65 = 4 cubed - 1 squared"

    > A variant of the intended answer involves moving one of the digits out of the equation altogether.

    65 = 4 cubed - 1

    > Stupid musical clues: Public Enemy, and Huey Lewis and the News.

    "We Got to Fight the Powers of Three", and "It's Hip to be Squared"?

    (When my son was in third grade, I think, he took a weekend math enrichment class at a nearby college. One week, he was excited to tell us about learning about "bono" numbers. We had no idea what he was talking about, of course, until he explained what they were, and we realized he had mid-heard the term "exponent". So, I was thinking about a U2 musical clue, but no one could have understood.)

  13. I wrote, "... Blaine's is a super, solid gold hint (so was mine)." Super is for the superscript of exponents and solid gold is for 24-karat, or caret which is used to show an exponent if you can't superscript.

  16. I agree that the answer WS is looking for is 65-4^3=1^2 (65-64=1).

    But I found an interesting alternative after remembering the challenge that relied on inverting a digital clock.

    Here it is:
    Invert the 6 to a 9, leaving 95-43=21 (wrong);
    Then move the 3 in front of the 5 leaving 93-54=21 (still wrong);
    The move the 2 in front of the 4 leaving 93-52=41 BINGO!!

    If you treat inverting the 6 as not moving it, but merely changing its orientation, then this alternate only moves (i.e., changes the relative positions of) two numbers.

  17. Just got back home so I can post now. I am surprised at the answers already posted because I came up with something very different.

    365-24=1

    Move the 3 and the 2 and you get 365 days (one year) minus 24 hours equals 1 day.

    1. Yet, mathematically that equation makes no sense.

      Hope your eyes are ok, sdb.

    2. I realize it is not a correct math equation, but I solved while still in bed and figured it was a trick question. Also he said nothing about inserting additional symbols, just moving two digits, which I did.

      Delete
    3. It's not much better chronologically, but I admire the outside the box thinking. Maybe SDB had a long weekend in Manhattans....

    4. I'm not sure now if I submitted my solution. I thought I did, but cannot locate the NPR response.

    5. Though, sdb, I'd argue that using exponents is not adding symbols.

  18. We came up with something creative akin to the digital clock reasoning...65-4=61...we took the three and the two and rotated both 180 degrees to make a six and place it in front of the one and voila! Curious to see if this is accepted; this logic was accepted in the past...why not again!

    ReplyDelete
  19. An alternative from your token Deplorable: Move the 3 into the 5 position; move the 5 into the 3 position while flipping and rotating the 5 to make a 2. Result is:
    63-42=21

    1. I wish someone would figure out how to post a reasonable looking equation with proper superscripts for the exponents. May be tougher than the puzzle.

      eco: I drove through Redwood Valley yesterday for the first time since the fire.
      The destruction is absolutely appalling, with hundreds of houses and other structures destroyed. I didn't go up Tomki Road where the worst of it is.
      The place I used to live survived, but the homes of about five friends and many more. acquaintances are gone. The randomness of what went and what didn't is hard to understand.
      Phone and power are still being repaired.

    2. Sorry for your friends and acquaintances, it's going to be rough up there. And that you still have no power too.

      I'll be going up there soon to meet with my clients, passing through the Santa Rosa burn, the traditional gateway to the normally happy, relaxing and beautiful countryside.

      Today, for fun, I dug up something in Windows Accessories called a Character Map, which has all sorts of arcane symbols, and put together my own. Let's see how well it matches: 65 - 4³ = 1²

  22. 65 – (4^3) = 1^2

    Sorry about missing yesterday, all. I was out on a birthday bash with a group of my former employees.

    ReplyDelete
  23. My alternative answer (which I did not submit):
    Move the 2 to the right of the 5
    Move the 6 (flipping it in the process) to the left of, and a bit below, the 1.
    Thus:
    65 - 43 = 21
    652 - 43 = 1
    52 - 43 = 9^1
    Two of my riff-offs on Puzzleria! involved equations containing 6,5,4,3,2,1 and 0. ViolinTeddy (and perhaps others) solved both.
    By the way, today's new Puzzleria! is uploaded. Sometime in the near future I plan to publish the "mother of all upside-down digital clock" puzzles.

  24. My last post didn’t go through for some reason...

    Here’s another answer: Move the 5 to the upper left of the 43 and the 2 to the exponent of the 1. That gives 6 - 5 base 43 = 1^2. You could also do the same trick by moving the 4 to yield 4 base 65 - 3 = 1^2.
