One stereotype about us #Autistics is we like #PrimeNumbers and #EvenNumbers. I'm a βyesβ and a βnoβ.
I do like Prime numbers and Odd numbers:
* 17
* 13
* 7
17 is very special.
* 17 is the 7th Prime
* 1 is an odd number
* 7 is an odd number
* 17 is an odd number
* 1 + 7 = 8, although an even number, it symbolises infinity and eternity, and us #ActuallyAutistics
13 is also special.
* A Prime
* An Odd
* A Fibonacci number
And depending on whom you ask:
* The 8th Fibonacci number
* The 7th Fibonacci number
Ironically:
* The anniversary of my first romantic relationship was on: 1997-07-17. It was my first love who picked that, and she had no idea what my favourite numbers are.
* My height is 175 cm or 5'75" to 5'85" (depending on whom you ask).
* Favourite time of the day: 07:00 and 19:00 (7pm). 19 is the 8th Prime. (There's 8 again.)
And I'm #OpenlyAutistic. ^_^

How about you? What two #Autism stereotypes is you and not you?

The relationship between numbers and my brain is one of mutual dislike.
My brain doesnβt do them. I swear I donβt 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 itβ¦

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 donβt expect me to do numbers.

@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.)

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

@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!
@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 rlthe 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 π
