Sounds perfect Wahhhh, I don’t wanna

personally the lattice method of multiplication is the reason i hate math

snowylynxx

youre telling me that i can make some boxes with lines through them

image

solve the multiplication equation for each pair of individual digits and arrange them in the boxes just so

image

AND THEN ADD UP ALL THE NUMBERS IN EACH COLUMN AND GET THE RIGHT ANSWER????

this post taught me that not everyone learned the lattice method in elementary school

In grade school we learned the normal way to do multiplication one day and then the lattice way the next, except I was sick the day we learned the normal way and they never went back and reviewed it and neither did I and so to this day I only know how to use the lattice method

....What the ever loving fuck, this is really cool???? I have NEVER heard of this???

I swear the jump from the first to the second image is basically that "draw the owl" meme.

Yeah it took me a while to figure it out, but I DID! So for me and you and everyone else going “wait wtf just happened????” I present a more step by step breakdown!

So you start with a grid with as many squares as needed to write one number across the top and one number down the side. And draw these diagonal lines through them. Yes you should extend them out the side.

THEN you basically multiply the numbers that match with each square, put the tens digit in the top triangle and the ones digit in the bottom triangle. Like so:

so once you’ve done that, you start adding up the numbers in the DIAGONAL column/row thingies from the bottom right up to the top left, like so:

image
image
image

You only want one digit (tho I assume if the very top/last row somehow gets 2 digits that’s ok, but ONLY in that position) and you’ll carry over to the next column, like if you were adding normally.

Then you start at the top left and just take all the numbers going down and around and put them together!

It does take up a lot more space and has a few more steps than the more traditional long multiplication, I think, but for people who struggle with that I think this would be a handy tool!

Here’s a screenshot of the more traditional style to compare:

I hope this helps! I had to figure it out on my own bc I was never taught this either. :)

So my astronomy prof gave us our pre-finals grades today and said if we were happy with them we could sign off on them and then not take the final.

Despite struggling this semester with ADHD shit that led to multiple missed assignments, I managed to scrape through with exactly 80%.

And as there is no way the test could bump me up 10 percentage points, but in worst case COULD bump me down 1, I don't have any need to take the final and I still managed to get a B in the class.

Thank FUCK.

WHOOOO CONGRATS ON GETTING A *B* IN ONE OF THE MOST ERUDITE SUBJECTS IN THE HISTORY OF CIVILIZATION

ruffboi-mags

Haha i mean, it was mostly a lot of VERY BASIC INFO AND THEORIES. Like, we didn’t even learn any of the maths ourselves, our textbook was “A Brief History of the Universe” and multiple days we covered the topic by watching an episode of that show “The Universe”.

That said, I’m still pretty pleased. Hopefully it bodes well for next year where I’m planning to take another one that had this class as a pre-req.

Being an Eridian scientist has to be so funny. You train your entire life as a biologist, becoming specialized in your field, probably giving lectures or educational speeches to other Eridians, and then the star savior Rocky comes home with his weird pet dog. Your job is now to cultivate food so the weird dog who is the age of average baby doesn’t die. The dog also saved the stars. Your job is making dog food out of the dog. You also learn that you and the dog have the same job. You are the happiest scientist on Erid.

The dog knows more about how the universe works than anybody else on your planet. The dog understands how relativity works and how the universe began. The dog has access to complex machines that can store and process massive amounts of information, launching your society into a new age of scientific and technological advancement.

You later find out that these machines were originally invented because the dog's species has a memory like a sieve and struggles with primary school level maths.

One thing that worries me about the use of AI is whether or not it can worsen people's dementia and alzheimer's in the future. When my grandmother was first diagnosed, we got her math activity books. Now, my grandmother never had a formal education, but we did our best to keep her sharp, get her to do math and writing activity books, sudokus, playing board games that required some level of strategizing with her. Her family is prone to alzheimer's and dementia (both her siblings had it and deteriorated very very very quickly, which yeah, scares the shit out of me being her granddaughter) but she was the one whose mind lasted the longest, she only passed away two years ago, at 88, ten whole years after her initial diagnosis and sure, she had forgotten things, recipes and where she put her glasses and appointments, but she never forgot any of us, ten whole years in, she still remembered us. Now, this may have been luck, but doctors always said the constant mental work + companionship + medicine helped her a lot. So I'm thinking, these people who are now relying on AI for everything, from email-writing to thinking what's for dinner to casual conversations, I've even seen people rely on it to calculate what time they should leave their house if they need to be at a place at a specific time and their commute lasts X number of minutes. As if that's not... the simplest math operation possible? You shouldn't even need a calculator for that!!! Idk I don't know how long it'll take us to see the effects of this + exposure to brain-rotting short form content that is completely meaningless + people addicted to right-wing conspiracy style media. Idk I'm very worried. Please, read, read complicated books! Take up a book on philosophy and try to decipher it and make your own opinions on it, please buy a maths activity book and relearn how to do math, please get a hobby that involves lots of thinking and concentrating. PLEASE!!!

As a neurologist, I’ll give you the pretty name for it: cognitive reserve.

The way I explain it to my patients is that our neurons don’t regenerate. They make connections with each other and that’s it. If you don’t use your brain, they make fewer connections and, if one of them dies, you’re gonna miss it, because that was the only one that knew how to do X. Now, if each one of them has many, many connections, you won’t notice the difference when one of them dies. The others pick up the slack.

As of 2024, 45% of dementia risk factors are modifiable. Relevant to this conversation, 5% for less education and 5% for social isolation.

We absolutely are going to see the reflection of this, but it’s gonna take decades and it’ll be too late. So, for the love of your brain, pretend that it’s a muscle and make it work. People complain about “when am I ever gonna use this maths formula in my life?” You’re not. You’re teaching your brain to think logically. Those sinapses will be there for when you need to figure out your week’s schedule. English classes taught me how to interpret data and how to convey it in this text so it’s clear and you understand what I’m saying, not because I needed to justify why the curtain is blue.

Make your brain know how to do different things. Logic games, puzzles, taking care of a garden even if small, planning a church’s event or birthday, learn a new instrument, learn a few words in another language, look at a calendar every day, do some manual labor if possible. Do not, I repeat, do not let your brain get rid of sinapses by letting AI do everything. Your brain uses 20% of your body’s energy — do you really think it’s going to maintain connexions that aren’t in use?

Most cases of Alzheimer’s are sporadic, meaning no family history. Family history of a first-degree relative with Alzheimer’s starting before they were 80yo increases your risk in 2-3x on average.

TLDR: Yes. From the knowledge we have today, AI will increase the number and severity of dementia cases.
