Things That Are and Are Not Changing as a Result of Re-Teaching Myself Basic Math

Things That Are Changing

I am less anxious about basic math.

I have more tools for doing basic arithmetic problems.

I'm better at identifying which will be the fastest or easiest tool for any given problem.

I can more quickly and easily ID when an exact answer is needed or when an estimate will suffice.

I'm marginally better at noticing when an answer can't be correct.

Things That Are Not Changing

I still transpose numbers frequently.

I still transpose operations frequently (adding when I should subtract, dividing when I should multiply, etc.)

I still have initial anxiety when looking at a math problem, before the "oh yeah, I have more tools for addressing this now" kicks in.

I still frequently mix up my right and my left.

My sense of direction is still bad.

I cracked Maths - No Problem! Textbook 4A today, putting me halfway through the series. I'm making this list for future reference, because I suspect the things that aren't changing will continue to not change.

Better math education won't change the fact that I have dyscalculia. I didn't expect it to, but I also didn't know what it would or wouldn't change. When I started this, I didn't know where my dyscalculia ended and my poor math education or math anxiety began.

Still, if we can fix "poor math education" and "math anxiety," I'll be much further ahead than when I started - and more willing to live with the dyscalculia.

it's no secret to anyone that knows me that math isn't my strong suit. and being a girlie who works in stem, that obviously is not going to work out. so i decided to start khan academy's math courses starting with the early math review.

my plan is to move up and see where exactly does my math skills start to waver so i can build up that weak foundation.

i'm excited to see where this journey takes me and where my math levels will be at in a few months!!

any resources will be greatly appreciated.

I was thinking through a young child sneaking into a high school might see learning and I had this thought. (I think I'm right I think I remember this correctly)

3! = 6.

! In math means you multiply by itself and each number down to 1. 3!= 3 * 2 *1

A kid might think of it like this.

The line is like a number line, and the dot means you multiply.

So this 3! Is more like this *--- and the number says how far you count down.

And the way the kid understands *1 is "dot 1 means you're done."

So 3*2*1 is 3*2, and 2 +2+2=6

So 3!=6

And 4!=24

Also I had the idea she's been hiding under a table and positioning a mirror to see the board so she learned to write backwards. She can sort of read forwards but she writes everything backwards and does math in the opposite direction.

Having basic computer skills and knowledge of the internet makes you understand male depravity and the scale of it so much more than the average person.

Whenever people accuse “misandrists” of being equally vile as incels, I always remember Porsche girl.

I learned about her when I was in high school, and just learning about 4chan and other male dominated forums. She was a girl that got into a car wreck that killed her, and destroyed her face. A cop leaked the photo sending it to his friends, and for years incels sent her mother pictures of her daughter’s shredded corpse. Her name was Nikki Catsouras, and her gore photos are immortalized forever due to male depravity.

That’s not even the most deprived case I heard of. Incels, for decades, have been on a level the most “extreme” misandrist would never stoop to. Please read any male dominated forum and educate yourself, you will stop feeling sorry for these creatures immediately. Esp trans identified men. You don’t even need an onion browser, just go to literally any one of their forums, even the heavily moderated Reddit ones, and you will be shocked by the amount of misogyny and aggression towards women.

My advice: stop feeling bad for men and learn basic cyber skills. Focus on making money and building female friendships. It will help you so much in life!

you’d think since dick was a mathlete hed b the number one guy to ask for help w math homework but actually he knows so much advanced math that the first time tim asked him for help with a simple geometry problem he pulled out his dusty ti-84 and started solving it in the most convoluted way that took an hour bc he was also just trying to relearn the math he hadn’t done in like 5 years. cue him screaming in frustration when he realized the actual way to do it would’ve taken him 2 minutes (tim asked him at the beginning if that way was right and he waved him off saying no) none of the batsibs can ask him for math help until they get to pre-calculus at least

love when men cry about body hair bc "it's hygiene" and yet 15% of cis men leave the bathroom without washing their hands at all and an additional 35% only just wet their hands without using soap. that is nearly half of all men. that means statistically you have probably shaken hands with or been in direct contact with one of these people.

love when men say that women "only want money" when it turns out that even in equal-earning homes, women are actually adding caregiver burdens and housework from previous years, whereas men have been expanding leisure time and hobbies. in equal-earning households, men spend an average of 3.5 hours extra in leisure time per week, which is 182 hours per year - a little over a week of paid vacation time that the other partner does not receive. kinda sounds like he wants her money.

love that men have decided women are frail and weak and annoying when we scream in surprise but it turns out it's actually women who are more reliable in an emergency because men need to be convinced to actually take action and respond to the threat. like, actually, for-real: men experience such a strong sense of pride about their pre-supposed abilities that it gets them and their families killed. they are so used to dismissing women that it literally kills them.

love it. told my father this and he said there's lies, damned lies, and statistics. a year ago i tried to get him to evacuate the house during a flash flood. he ignored me and got injured. he has told me, laughing, that he never washes his hands. he has said in the last week that women are just happier when we're cooking or cleaning.

maybe i'm overly nostalgic. but it didn't used to feel so fucking bleak. it used to feel like at least a little shameful to consider women to be sheep. it just feels like the earth is round and we are still having conversations about it being flat - except these conversations are about the most obvious forms of patriarchy. like, we know about this stuff. we've known since well before the 50's.

recently andrew tate tried to justify cheating on his partner as being the "male prerogative." i don't know what the prerogative for the rest of us would be. just sitting at home, watching the slow erosion of our humanity.

The maths fandom is wild. “Real” and “imaginary” numbers? I think you mean canon and non-canon. You guys seriously go “this is my number oc his name is i and he is the square root of -1” when in numbers canon lore it’s actually impossible to square root a negative but sure whatever. “Complex numbers”? I think you mean a character x oc ship. “f(x) = 3x - 5”? That is self-insert fanfiction.

We Were Fifty Pages Into the Second Math Book When the Dyscalculia Kicked In....

I spent the last couple posts talking about how bad my early math ed was. You may have wondered where the dyscalculia fits in.

It's here.

This is about 50 pages into Maths - No Problem, Textbook 2A. It's the second lesson introducing subtraction of two-digit numbers.

It's the first place we have to deal with "borrowing" tens. It's where arithmetic really started to mess with me as a kid, and it is the first time in these math books that the pictures and alternative methods really aren't helping as they were before.

Ah, subtraction with borrowing tens. Once again we meet, and once again you make me feel like my brain meats are merely decorative.

Strategies I am using to overcome the decorative brain meats and try to understand what I am doing:

Actually using concrete objects to count and make groups. (I'm using dried pinto beans.)

Doing each problem at least two different ways.

Writing down my steps so I'm not unnecessarily forcing myself to hold numbers in working memory, which is hard for me and leads to easily-avoided mistakes.

Muttering "you're just subtraction; I have a passport and a credit card, what can you do to me?" when I start feeling like the numbers are laughing at me.

That last one is surprisingly effective.

i learned of a 34-year-old Japanese mathematics professor who decided to host his lectures on… Pornhub.

His earnings of €250,000 per year stem from the fact that even though many may not be interested in the subject, they are nonetheless curious about his presence and attempt to watch the video, generating views.

5 months of studying math and logic on brilliant, I'm quite enjoying this app, specially since it used to be my least favorite subject (math).

Unrelated: A lot of people think they'd be mages in a fantasy setting but don't know anything about math or programming in their current lives.

The world they already live in has a magic system and they just neglect it. They consider it boring or impenetrable.

Honestly I kind of sympathize since school is usually horrible at teaching that kind of thing but still. The most wizard-coded people are the ones who Understand Math.

love it when i understand a math concept. my brain expands by 2% but i love that little rush of "oh!! i get it now" and i crave it so much.
