Read it somewhere, forgot the detail. It’s actually true. He admits that the questions was ‘a bit harder’. He then submit it to the professor, thinking that he might be miss the deadline. The professor read it, surprised, and make some publication or something, ofc with his name. By that time, he’s still in his 2nd (or 3rd?) year. So when he’s about to make his thesis, he asked the professor for some suggestion. The professor basically says ‘LOL, just wrote that solutions again on a paper or something, I’ll accept that as your thesis’.
I had a similar experience but not as extreme: I was supposed to solve a few limits without the use of l’hopital’s rules because we hadn’t learnt about them in the course. Since I didn’t know what the rules were, I didn’t know what to avoid so I accidentally reinvented them and of course failed the question.
“here are the answers to that homework you posted, sir”
“homework?” *looks at a piece of paper handed to him*
*EYES WIDEN*
“So, how would you like a postdoc position in my group?”
“Sir, this is the 2nd year of my Bachelor, isn’t that a bit early?”
It only took me 15 seconds but I think it’s 63.
something similar happened to me once, i also got late to class
Bro we got Einstein… hidden figures addition up in here

So what were the problems??
And here I am too ill to write it down.
That is like copying the genome of cancer and got the cure
My ADHD brain:
Well if 7×10=70 then -7=63 , =9×7

It took him like 5 days or so of just working on it and everyday he hoped his teacher wouldnt remember the “homework”. Serious dedication on that man
Not to be confused with Glenn Danzig
That’s why you should teach Dantzig
How to multiply 9 * 7:
1. The magic number for 9 is (1) for 8 is (2) and for 7 is (3)
2. From the other number subtract the magic number -> 7 – (1) = 6
3. Now subtract the other number from 10 and multiply by the magic number -> (10-7) * (1) = 3
4. The answer is 63
How to multiply 7 * 9:
1. The magic number for 7 is (3)
2. 9 – (3) = 6
3. (10-9) * (3) = 3
4. The answer is 63.
This is what peak masculinity looks like
imagine he didnt come late to class 👀
I find 9×7 easy. I keep getting stuck remembering 7×6 and 8×6

There Is beautifull saying from a classic polish movie :
“If something can’t be done, there is a need for someone who doesn’t know about it, that will come and do it.
You need to learn some speed multiplication tables. 10×7 is super easy, and for 9’s there’s a whole micro-algorithm where two digit numbers add together to equal 9, so a good math person who struggles with one can fallback to the other, or an even better math person might double check the first with the second or vice versa whichever way works for their thought better. For 9×7, if the numbers are too big to immediately think of(i learned in the days where everyone remembered everyone’s phone numbers so I maybe have unfair advantage) pretend you are doing division for a wink of a moment. What addition-operation of digits since it is the 9 multiplication table, add to 9 and are divisible by 7? if you knew your 7 times table simply seeing 7 you might flash through all the single digit multiplication results in your mind, 7-14-21-28-35-42-49-56-63, and if you have extra mental acuity you’ll see the digits add but only one pops up for the factoring of 9. Then you could just mentally think 10×7 and remember you minus 7 from that to get, 63, as a error correction side step.
Just always remember numbers are built that way to chew on by humans for humans, you can do things so long as you know exactly what you did and why to get somewhere faster, as long as you finish showing your results so you can double check yourself at the end.
My personal math problem problem is basically everything above basic math. My brain never developed a proper stencil to intuitively retain exactly how factorials work, x/y axis slopes and the polarity of the numbers that are spit out to define a line on an axis, and I would need to learn the mathematical formula shorthand symbols to even begin working on whatever is in that pic which without something really hammering in what they are and why they are, its like trying to strike a coin with a die cast of cheese.
When I read this I always think about how much the fact that he thought it was homework played a part in him solving it. It didn’t get to his head that it was an unsolved problem, he thought it was the usual so, to him it was solvable from the start.
Mindset is everything.
