I like prime numbers too. 1973 is a prime number. I was born in 1973.

I was once involved with a Math Savant. He was also a sociopath and not on the Autism Spectrum.
Cold, manipulative and intellectually sexy .
When a boy tells you he’s an Ubermensch and a Master and can quite Also Spract Zarathustra it’s time to run, don’t walk, to the nearest exit .
He has a fetish for domination via Infintesimals and Set Theory .

@youronlyone @autistics @actuallyautistic @actuallyadhd @autism I don't see how anyone can NOT like primes

@MishaVanMollusq Usually depicted in some shows/films, where the autistic character prefers their food to be even and/or in prime, otherwise, they'll throw a fit or won't eat.

IRL, I've heard it said years back that people who love Primes, and if combined with Even numbers, are "more likely autistic". I guess it also stems from the stereotype that autistics are savant.

@Waiting4Thunder @ScottSoCal @masukomi @youronlyone @nellie_m @autistics @actuallyautistic @actuallyadhd @autism @pathfinder you can do the nine times table on your hands. Hold up ten fingers. Put down the one on the left. You have 9. Put that one up, and the next down. You have 1, 8. Move the finger along, 2, 7, then 3,6 and so on.
To get for instance 9 x 7 put down the finger 7 from the left, and you have 6 fingers on the left and 3 on the right!

@Waiting4Thunder

I never noticed that before - that's actually kind of cool.
The addition part is also true for 9x12=108.

@ScottSoCal @masukomi @youronlyone @nellie_m @autistics @actuallyautistic @actuallyadhd @autism @pathfinder fun trick, the lower times tables for 9 have products that would total 9 if the digits were added together and the first digit is the multiplier minus 1

9x1=09 (1-1=0, 9-0=9, 0+9=9)
9x2=18 (2-1=1, 9-1=8, 1+8=9)
9x3=27 (3-1=2, 9-2=7, 2+7=9)

This works up through 10!

Memorization was the bane of my life as a gestalt style learner 😅

@youronlyone @autistics @actuallyautistic @actuallyadhd @autism
I had not encountered such a stereo type before

@ScottSoCal @masukomi @youronlyone @autistics @actuallyautistic @actuallyadhd @autism @pathfinder

you’ve lost me 🤣🤣🙂

@masukomi It's similar, memorize the big grid. But I can only do 1-5 and 10.

I calculate 6, 7, 8, 9 by using my hands (I learned to visualise it mentally).

Here's a video I found: https://www.youtube.com/watch?v=x2Nr-f02AUY

I can't get my head with the multiplication table for 6 to 9, but after someone taught me the hand way, it worked.

@nellie_m @autistics @actuallyautistic @actuallyadhd @autism @pathfinder

@masukomi

Memorizing that grid of numbers didn't work for me, so I worked out other methods.
x9, for example, I count down from 9x9=81. 9x6=
81, 72, 63, 54 - ah, yes, 54.

@youronlyone @nellie_m @autistics @actuallyautistic @actuallyadhd @autism @pathfinder

wait no. now i NEED to know about your multiplication tables for 6,7, 8, and 9. When i was taught everyone just memorized this big grid o numbers from 1 to 12. How did you do it?

@nellie_m Same! I'm poor with mental calculation, but I love the logic behind mathematics.

LOL. I remembered (Grade 9 and 10) some of my exams wherein I failed because my solutions were weird. I did arrive at the correct answers, but getting there was what's graded more. (And my teacher then understood the way I think, so she showed me why I was wrong by testing my way against other rules. I really appreciated she explained it.)

I don't like maths, but ended up being chosen as class maths teacher substitute in Grade 6. Our maths teacher saw something, I guess how I understand the logic behind it, even though I can't do mental calculations. (Don't even ask me about my multiplication table for 6, 7, 8, and 9. Hahahah.)

@youronlyone @nellie_m @pathfinder I've managed to learn French, and a little Russian. I can read out loud some text in either of those language, until I hit a number. In the case of Russian it's because numbers have case and I'm never quite sure which case the situation calls for. In French, it's because the way French treats the numbers 70-99 (and numbers that end in 70-99) is a regular clown show.

@youronlyone @autistics @actuallyautistic @autism IME, "Autism awareness" ends with the awareness that Autism *exists*. Nothing about how Autism actually presents in the world (especially among marginalized folx, girls, and adults of all races and genders, but especially marginalized folx and women), how it feels, how an Allistic person might interact more effectively with their Autistic coworkers, family members and friends ...

@youronlyone @autistics @actuallyautistic @actuallyadhd @autism @pathfinder

The relationship between numbers and my brain is one of mutual dislike.

My brain doesn’t do them. I swear I don’t even know what numbers are. As a kid, I learned mental arithmetics like a poem. I recited it in every test, for every exercise. What I wrote was mostly correct, but time was always up before I had finished even half of it…

I can literally count to three, that’s it.

I’m very much a verbal thinker. I love learning languages. Drop me off somewhere and I’ll speak that language within three months, complete with proper local accent. No problem. Except for, of course, the numbers!🤣

maths was my poorest subject until we were allowed to use electronic calculators. Late 70s. And then suddenly, it became fun! I loved algebra so much. Being able to do maths with my good old friends: letters!

At that point, I chose maths as a favourite subject even. I loved how unambiguous and logical and elegant it was. Just don’t expect me to do numbers.

@lori Wow! I had to read that! ( https://en.wikipedia.org/wiki/Heptadecagon )
