I'm 60 years old now and although I have done this level of maths a long time ago and can still do it, it's fun learning terminology I was never taught.
We dont actually use parenthesis to represent that the interval doesnt contain that number , we used like this ]...;...[ At least thats the way i was taught
To me it seems obvious. Summing all the natural numbers, all being positive, using Ramannujan's infinity series cannot equal a negative number, therefore it cannot be applied to the natural numbers.
That's because it uses a Cesàro sum. Not the, for lack of a better word, 'real life' sum. The whole problem with 1+2+3+...=-1/12 is that they assume that 1-1+1-1+... gets the value 1/2. This is simply not true, since it never converges. Now don't get me wrong, it's super interesting. But I think that because of the fact it is not true with the real life summation, the topic does not quite fit Mr. Woo's type of videos. He teaches maths to kids, which means it has to be accessible to what they know of the world. He is very talented in making kids able to grasp some more abstract things, but for this topic you need a little more background in maths, I think.
I pity you. If you can't do the maths then do something else. Life's not about achieving wealth, it's about achieving your own wellbeing while maintaining your integrity.

Thanks for this video you are the best sir

Hey could I send u an interesting math problem, and if so, where should I?
I want you to shoot a video on ramannujan's infinity series explain how can it be possible sum of positive natural is negative
