I remember learning this out of curiosity in the past, but math doesnt stick in my brain unless chemistry is used as a disguise. Where can I read about this method again? Will the wiki page on Gauss get me there efficiently enough?

I found that pretty handy. Came across it looking for a Numberphile video on the subject. I was pretty sure I’d seen one before but didn’t have a lot of luck finding it.
Just wanted to say thanks! Clicking your link made me realize I should try to figure out how to open up YT on PipePipe automatically, so now my phone works better :)
No problem. I have a script that automates generating the title and link to a video when sharing automatically.
I should look into having it do the same for pipe
So was he writing backwards, or did they print a custom flipped t-shirt?
I’ve always wondered how they do that. Because writing backwards would feel so weird to me
The sum of all natural numbers smaller than and including x is equal to
(X+1)(x/2)
The sum of all even numbers up to and including x is that minus (n/2)² so
[(X+1)(x/2)]-(x/2)²
That would mean the sum of all odd numbers under x is equal to
(x/2)²
or sum of all odd including x (if x is odd of course) is
[(x+1)/2]²
Since the sum of all even numbers up to x is the sum of all numbers minus the sum of all odd numbers.
[-(X/2)² +2x +1]/2 (another way of writing the sum of all evens under and including a number) looks suspiciously polynomial. I want to go further.
(X+1)(x/2)
And what’s the big X here?

This appears to do a nice job with pictures. Although I did not read it all the way through. letstalkscience.ca/…/gauss-summation

you’ll either get there, or to the Boston Molasses Disaster, so you’ll learn something cool either way.

I know about this one! I think it was a Reactions video, which I believe is the American Chemical Society’s yt channel
