Viral IQ Test Only Albert Einstein Could Pass | The Correct Answer Explained

[@ralphparker]

The problem with these kind of problems is first the way it is presented. It is not 1 + 4 but should be F(1,4) or function of ( 1 and 4). The second is that any reasonable rational that leads you to the correct three answers is a valid solution to the problem. If the rationale correctly produces the first three answers, then the answer you get is correct and there can be many correct answers as long is your logic is applied correctly.

@@ralphparker If political conservatives want to defend English as the official language of the USA, then I believe that they should all start by learning how to spell. The internet, along with political protest signage, is often filled with bad spelling. You'll even see bad spelling prominently, and not intentionally, featured in company advertising. 15 years will go by, and such companies will leave the misspelled words misspelled. The English language is taking a beating. I was once even forced to have a manager who could never figure out how to spell the word _Wednesday._ He knew there was an *n* in the word, but he never knew where to put it. Right now, there seems to be an unspoken initiative, all across the internet, to "do away with" singular versus plural spellings of words. Most notable is the assault on the word _woman._ Everybody seems to be transitioning to spelling the word _women,_ even when speaking about a single woman. Personally, my command of grammar could always use some work, but you have to start somewhere.

@@JohnBerry-q1h That's all well and good. But if you are going to correct everyone who misspells a word on the internet or makes a typo then you've got a big job ahead. The rest of us are here for the entertainment value. I do watch for the program to highlight questionable words and I will fix them. But sometimes I misspell a word but it matches another word so it gets missed. English is not my best area and I try but growth is very slow if at all.

1 + 4 =5. 2+double 5=12. 3+treble 6=21 4+ quad 11=52. Took about 20 seconds.

On first row add everything to the left of the equal sign 1+4=5. One the second row you have 2 +5 which equals 7 BUT you ALSO add the 5 from the first row which gives you 12. On the third row you add 3+6 which is 9 but you also add the 5 from the first row and the 7 from the second row WHICH gives you 21. The fourth row is 8+11 which if 19 then you add the 3 previous rows ( 5 , 7 , 9) AND the answer is 40. This is a pattern problem which my brain is built for ( I am slightly Autistic) and I taught myself ( without math books, worksheets, videos or help from my parents) using trips to the grocery store and counting money , so that when I went into kindergarten ( at 4 about to be 5 ) my math Knowledge was about the level of 5th to 6th grade , but I could do mental math better than most adults. Did not go to college because of severe dysgraphia ( no computers IPads back then) and severe ADHD. Let me assure you that this problem DOES not require that level of ability, but it does help catch it faster. Pattern recognition is still with me along with my severe hatred of writing 🤣.

So , not enough information given if you have three methods and three answers, two coincidentally the same. Great for a brain teaser but not so good for an engineering solution where that extra 56 can make a difference

[@captainwasabi]

base 6, base 5, base 4, base 3 (so the answer is 201)

[@Random3.142]

Agreed, that was my answer too before I watched the video

1 + B1 = (1+B1) 2 + B2 = (1+B1) + (2+B2) 3 + B3 = (1+B1) + (2+B2) + (3+B3) ... k + Bk = (1+B1) + (2+B2) + (3+B3) + ... + (k+Bk) ... n + Bn = (1+B1) + (2+B2) + (3+B3) + ... + (k+Bk) + ... + (n+Bn) We have : Bn - Bk = n - k We therefore have : n + Bn = (1+2+3+...+n) + (B1+B2+B3+...+Bn) = ( n ( n + 1 ) / 2 ) + (Bn - n + 1) + (Bn - n + 2) + (Bn - n + 3) + ... + (Bn - n + n) = (n^2 + n) / 2 + n * (Bn - n) + 1+2+3+...+n = n * Bn - n^2 + 2 * (n^2 + n) / 2 = n * Bn + n = n * ( Bn + 1 ) In summary, both solutions give the same answers : 8 + 11 = 8 * (11 + 1) = 96. However, these two solutions are not completely equivalent because the second (the one that consists of adding all the previous results) requires more conditions to be applied in the general case. Indeed, the numbers on the left must be (in order) strictly positive integers and starting with 1, then 2, then 3, etc. (assuming B1 is non-zero). Furthermore, for each equality, the difference between the number on the right and the number on the left must always be the same.

Is this some way to mesure brain skills? How? Or is it just a puzzle (for fun)?

[@problem_analysis]

This problem has a history of appearing on math competitions for students of elementary schools. It has also appeared numerous times on various iq tests.

[@DiegoSimonetti-zc8yj]

8 + 11 = 96 perché se 1 + 4 = 5, 2 + 5 = 12 , 3 + 6 = 21 allora 8 + 11 = 96 perché 8 + (8 × 11) = 96 in generale a + (a × b) = c

[@dr.frankesposito4351]

One answer is 52. ie 8+ 4×11=53

[@dr.frankesposito4351]

should be 52
