This is now the most watched video on YouTube featuring the Lambert W function, and also introducing many people to Knuth's up-arrow notation. And yet the math meanies never praise or share my videos! Math negativity is a huge reason why so many people dislike studying math…(more details below)
People often send me puzzles they see on social media. They love these videos because learning how to solve them helps builds their confidence in math. The few negative comments must come from people who don't actually watch the videos–nearly everyone who watches them praises them very highly (100+ million views, Shorty Award nominee, praise from famous mathematicians, citations in books/papers/courses, frequent media mentions, positive reviews to my many books, etc.). Take it from me: don't listen to the confidence crushers/math meanies/dream destroyers! Everyone agrees negativity is hurting math education, so we need to be extra positive to cancel them out!
Im going to watch this video to see why its not the obvious answer of 22.
I am SMRT. If ballons can equal numbers they can equal question marks. The answer is "??".
If a single blue balloon = 1.56 them how 2 green – 2 blue balloons = 2?
21
In my opinion based on visual interpretation + exemple 1 where answear is 21, you can have 2 other results : 31 and 11 . based on green's baloons arrow
you missed a point, IF length of arrow matters or not.
of coz longer arrow mean heavier too, but the balloon raise higher than shorter one, they have exact same volume, so the gas mixture in each ballon is different
It's 21 which is approximately equal to 21.56. 🤦🏻♂️
After all the balloons I was hoping there'd be cake and ice cream.
If:Red+Red+Red=30
Red+Green+Green=18
Green-Blue=2
Then:Blue+Red*Green=(42)
real genius: find the easy pattern in a messy looking pile of information.
so the real genius will answer 21.
Wannabe genius on the other hand…
Answer is =21, as red=10, green=2 and blue=1
Thank God I learn about business and not engineering😂
Have you seen that the arrows below the green balloons aren't the same size but the arrow below the blue balloons are🙈
I’ve never heard of that kind of math, my answer was and still is 21.
POWER TOWER!
Didn’t you notice that the green balloons have different length in their arrows? We can consider the short arrow of green balloon=1 while the tall one = 3 , so the final result will be 31 . Seriously, that makes sense 😂
I got 21 is that the right answer?
13
This was gross over complication of a simple puzzle. We were not exactly trying to ensure the absolute accurate amount of rocket fuel to be filled in a rocket before its launch where a very very high degree of accuracy is indeed required.. In most real life situations none would bother about 21.56 and 21. This is not material at all. After all the technical application what you got was 21.56 and the ordinary mortals like me got 21 in less than 2 minutes. Sorry but not impressed with this sort of intellectual masturbation.
No… it’s brown… red and blue make purple mixed with green make brown… so there!
I got the answer as 21
Following the operation rules it is 21, doing the operations from left to right it is 22. And with higher mathematics it is "something inbetween"? C'mon!
My only issue is since both the balloons are exactly the same. They should represent the same number. Not X & Y
Basic answer
Standard calc: 22
Scientific calc: 21
what about the different length of the arrows at the green balloons???
48 48 48 48
I got 1+10×2.66=27.66.
Knuth, tetration and W functions?! I thought I'd done some fairly advanced maths in my time, but I've never heard of those. I'll stick with linear equations.
Sorry, but 22 is the answer and I got it in 20 seconds. Your figures took you how long..? Time is money man…and you would be fired!

I got 21! I thought I'd done something clever….how mistaken I was….
I think the simple interpretation is the correct one…the puzzle requires you to provide an exact solution, not an approximate one….
Answer is 21. ez
You're over thinking it. These kinds of puzzles are meant to test innate intelligence and reasoning ability as apposed to one's educational level in mathematics.
3:21 when u get correct answer in examination but u over think and u get different answer😂😂
I am confusion why do it so hard
21
To make things more complicated, in morse code, a dash (a long arrow) is T, two dashes (two long arrows) are M, a dash and a dot ( a long arrow and a short arrow) are N. Combine this with Lambert W function and Knuth's up-arrow notation, you will get the answer of …… brain blows up
