Each few months, a math drawback goes viral on social media. Disappointingly typically, it lacks mathematical meat. It appears over half of them boil right down to the order of operations. Some tweet will get hundreds of likes claiming that the Web is split over an arithmetic drawback like: what does 6÷2(1+2) equal? It’s positive if individuals don’t keep in mind how one can consider expressions like this. However it’s not so fascinating whenever you simply should Google the order of operations and comply with the directions (it equals 9).
In an analogous vein, you will have seen “fruit math” memes circulating throughout your feed during which easy methods of equations have “x” and “y” changed with bananas and pineapples, normally captioned with “Solely geniuses can resolve” or “Just one% of MIT graduates bought this.” Right here’s a hilarious prank that some Web satan cooked as much as lash out at frivolous math clickbait:
I’ll prevent a while and spoil the answer:
Apple = 154476802108746166441951315019919837485664325669565431700026634898253202035277999,
Banana = 36875131794129999827197811565225474825492979968971970996283137471637224634055579,
Pineapple =

Certainly, 95% of individuals can not resolve this. Regardless of its simplistic look, the issue requires extremely superior math and wasn’t solved till 2014.
This week’s puzzle comes from an actual drawback on a math take a look at given to college students in Singapore. It’s neither trivial nor a prank, but it surely went viral for inflicting rifts amongst solvers. It’s a difficult train in logic not like any examination drawback from my faculty days.

Answer to Puzzle #21: Not possible Geography
How did you navigate final week’s bizarre geography quiz? For those who discover the primary two solutions onerous to consider, mess around with Google Earth to see them for your self. Shout-out to Executor32 for nailing all three.
- Which U.S. state is closest to Africa?
Many individuals suppose Florida, but it surely’s really Maine by a protracted shot. Africa sits extra north than you would possibly image. Executor32 factors out that if Puerto Rico ever turned a U.S. state, it will beat Maine on this contest, as a result of Puerto Rico sits east of Maine.
- For those who fly due south from Key West, Florida, which South American nation will you hit first?
You really received’t go over any South American nation in the event you fly south from Key West. You’ll soar west of the entire continent.
- I’m in an East Coast U.S. state and I name my pal who’s in a West Coast U.S. state. It’s precisely the identical time of day for each of us. How is that this doable?
Sometimes, there’s a three-hour time distinction between East Coast and West Coast states. We’ll shut this hole one hour at a time. Though Florida is an East Coast state, the a part of the panhandle below Alabama really dips into the central time zone. Likewise, an japanese swath of Oregon (a West Coast state) observes mountain time. So there are areas in Florida and Oregon whose clocks solely differ by an hour. To bridge the ultimate hole, I place the decision on Daylight Financial savings Time within the fall when the clocks roll again an hour. At 1:59 am in elements of Florida on today (simply earlier than the clock falls again), will probably be 12:59 am in elements of Oregon. Within the subsequent minute, Florida will fall again and will probably be 1:00 am in each locations. I then have an hour to position my name earlier than Oregon falls again. This telephone name can solely happen inside this particular hour of the yr between these two particular areas of the nation.
