i have a masters degree in math but i still use a calculator anytime either of the numbers is 2 digits or more

[–] showmeyourkizinti@startrek.website 14 points 4 months ago

Seriously I’ve got a Batchelor in Math and the more higher maths I learned the worse my basic maths got.

[–] kichae@wanderingadventure.party 6 points 4 months ago

affiliate@lemmy.world I have a masters degree in physics, and I just straight up don't do mental math, and never have. Math is for pencils and notepads. And I love pencils and notepads!

10 + 10 = ... hold on, where did I put that thing? 🤔🤪

WRONG! 1010 = uh... 10 actually?

I may need to rethink my life.

[–] Rusty@lemmy.ca 4 points 4 months ago (1 children)

This is correct in JavaScript math

[–] OpenStars@piefed.social 2 points 4 months ago

Concatenation, then binary -> decimal. Computers are weird. People are weirder. 🤪

you're breaking my brain! 🤣🤣

When Common Core math came out and people were up in arms against it, I wanted to know what the big deal was. I researched it, read that it makes mental math easier, and deciding to learn/practice it myself.

I understand the parents who struggled to help kids with their homework, since they weren't taught the same way and if you're just thrown into it, it's hard to figure out. Though how it turned into this big hullabaloo was an extreme reaction. Mental math has become very easy for me since learning it, which makes me think many of us missed out on a method that could've helped us a lot.

So, no, I don't struggle with math. What I struggle with is the confidence to believe I've come to the right answer. I usually do math calculations more than once because I doubt myself. My first college mathematics professor gave me a reality check about it once, as he was getting frustrated that I wouldn't put my hand up even though he knew I had figured out the answers. I can still see him standing there, going, "Come on, Whats_your_reasoning, I know you've got it. What's the answer? Just say it!"

Common Core everything in general is pretty solid. You know how people like to complain about critical thinking not being taught in schools? Well CC English classes at the end of HS are all goals like finding textual evidence to support an opinion, or distinguishing between stated text and actual meaning (vis a vis satire, irony, etc).

The real problem is underfunded schools not having the resources to address student needs, not the teaching aims themselves. Imagine if every classroom maxed out at 15 students, just for one simple thing we could do to start fixing shit.

Here are CC standards for 11-12 grade reading and writing

Yeah I remember looking into it back when people were freaking out, and I realized that it was basically how I taught myself to do mental math like 30 years ago.

Did they ultimately get rid of Common Core? Or did people finally just shut up about it?

[–] nickiwest@lemmy.world 2 points 4 months ago

Many states adopted their own standards instead of the Common Core, likely because of the political backlash. Most that I've seen are 90% CC with some state-specific requirements for things like history.

[–] toynbee@piefed.social 1 points 4 months ago

I've never really interacted with Common Core in any form; I was out of public school long before it became commonplace and I guess my kid isn't old enough to encounter it yet. As such, I have no real opinion nor understanding of it.

However, whenever I interact with people discussing it, I think of Tom Lehrer.

[–] pedantichedgehog@sh.itjust.works 9 points 4 months ago* (last edited 4 months ago) (1 children)

I was the opposite. Math was, if not easy, then simple. Every math problem has a specific set of steps you take to solve it, and a single objective answer. Unlike literature, there's no room for differing opinions or interpretation. It meshed very nicely with my black-and-white worldview.

[–] calculuschild@lemmy.zip 2 points 4 months ago

Same here. Math was the one place I felt like things made sense. The subjectivity of arts and literature drove me crazy.

[–] eupraxia@lemmy.blahaj.zone 7 points 4 months ago (1 children)

I have studied so much goddamn math in my life...

...and yet the hardest parts of being a trainer has been a) counting reps and b) subtracting 45 from a number and dividing it by 2.

[–] Gust@piefed.social 1 points 4 months ago

That last one is easy. Given any x,

(x - 45)/2 = lost gains. If you still fit through doors, put that plate back on

The derivation is ~~a bitch~~ left as an exercise for the reader

[–] LodeMike@lemmy.today 7 points 4 months ago (1 children)

Just because you're not good with large logical operations doesn't mean you're dumb.

Within the margin of error.

My dad lost faith in my Math skills when I guessed the result once

[–] prenatal_confusion@feddit.org 6 points 4 months ago

Sometimes I divide numbers by ten and just the moment before I press equals I realize what I've done. But then it's to late.

[–] purplerabbit@piefed.blahaj.zone 6 points 4 months ago

I have dyscalculia. So call me Mason because I have no fucking clue what the numbers means.

[–] OwOarchist@pawb.social 4 points 4 months ago
1000/44.94
= 22.25189141076991544281

22*44.94
= 988.68

100000/44.94
= 2225.18914107699154428126

2225*44.94
= 99991.5

16*3.33
= 53.28

39-11
= 28

There. I don't think I have anything to be particularly embarrassed about. Well, except maybe that last one.

[–] protogen420@lemmy.blahaj.zone 3 points 4 months ago

math was the only fun subject to me

[–] mickus@sh.itjust.works 2 points 4 months ago

I struggle with arithmetic. Generally i do think this is a case of just not using it, thanks to calculators

[–] Lexam@lemmy.world 2 points 4 months ago

I'm gifted in other ways.

[–] benderbeerman@lemmy.world 2 points 4 months ago
[–] Filetternavn@lemmy.blahaj.zone 2 points 4 months ago

I can do arithmetic without a calculator, it just takes me a lot longer. Simple addition/subtraction/multiplication/division? It can sometimes take me what feels like an "embarrassingly long* amount of time. Multivariable calculus though? I breeze right through it (it's the basic arithmetic involved with it that takes me most of the time lol)

[–] HubertManne@piefed.social 1 points 4 months ago

I had issues with making mistakes over long calculations. So math where your calculations were like a page long meant I would very likely have the wrong answer. So basic math no real problem and begining algebra to. then advanced algebra bad. geometry and trig good. precalc and whatever was put with it bad. beginning calc good. advanced calc and differential equations. ugh. im not really sure if im autistic or adhd or anything but im definately not normal. that is any place I worked im fairly sure im the wierd guy but like quirky weird. i mean not everywhere. im in tech and I have worked in places where I was closer to norm.

[–] aproposnix@scribe.disroot.org 1 points 4 months ago

Yup. Its called Dyscalculia.
