#hecking math

[floating-feelings]

I found your blog randomly and saw your post about struggling with math. I hope this isn’t out of line coming from a total stranger, but have you been tested for the learning disability called dyscalculia? I have it myself and getting tested for it answered a LOT of questions about why math was so difficult for me. If you have it, you can get accommodations for it in school! Sorry if this was inappropriate, but I didn’t want to leave without dropping that info just in case it may be helpful.

aw hi there! not inappropriate at all, thanks for caring! 🙏 Yes i actually have, when i was about 15 i was evaluated for dyscalculia. I was apparently super close to getting the diagnosis but was a little too quick with some assignments to actually get it 🙃 I got an autism diagnosis later on though which made sense with my uneven cognitive profile. I did get some accommodations for my autism during this math course, at least. I hope youre doing okay stranger 🌸

if I had any kind of artistic prowess, I’d draw Clark with a mild ‘I’m about to wreck shop’ smile, grabbing at his hair, glasses halfway down his nose while helping Jon and Damian with their math homework.

“Pa, they want us to do it THIS way-“

“BUDDY. MATH IS M A T H.”

Trying to focus with chronic pain, fatigue, and brain fog is such a fucking joke. I want to remove my brain and punt it.

#heck!!! #chronic pain #this is about my many math assignments that i need to finish #but also life in general

how do i adequately express my love for math for an admissions essay. "talk about a stem subject that excites you" how do i put that this is my art and the most beautiful thing in the world and fills me with such a sense of enchantment that i feel as though my breath has been taken away into less than 750 words and make it cohesive

#mathematics #math #mathematiques #mathblr #i need to get into this school what the heck #bro #this needs to be the best essay ever and has to be not too poetic or whatever but also express that it isn't really an essay as much as a #ran out of characters- love letter #AAAAAAAA #i have so much to say and cant figure out how to say it

Does Opal still speak very formally around Team Skull? Because this scenario is playing out in my head and I want you to hear it.

Opal: *says something in an archaic manner, the specifics don't really matter*

Skuntank: "Chaw-haw! Uh, Yeah! Sure I can do that!"

Opal: *content, leaves to go do something*

Skuntank: *leans over to zubat and koffing, sweating* "Do either of you boys know what I just agreed to?

Oh my word.

#Team Skull rapidly flipping through the thesaurus they’re all hunched over so they can understand what the heck their goddaughter said #I’m having flashbacks to the day I made a guy in my math class genuinely freak out bc I was speaking entirely in biblical english #I thought he was kidding about it being weird and unsettling #he wasn’t :[ #he was lowkey terrified of me for the rest of the year #turns out this isn’t a skill everyone is able to whip out at random? #which felt fake to me as a youth #Like #No. Everyone is able to do that #Just like how everyone reads dictionaries cover-to-cover for fun as a 3rd grader! #/Obviously./ #shadow baby au #pmd team skull #pokemon mystery dungeon #pokémon mystery dungeon #pmd explorers #pmd sky #pmd eos #pmd2 #pmd #sofie answers asks

I'm trying to make sense of My Strawberry Film and the colors.

Ryo is a Brown Boy and Hikaru is a Blue Boy.

See the brown? Yes!

And see the blue? Yes!

But the red/pink ball of 💕love💕 has to mean something, right?

So we have the boys' colors, but what about the lady friends?

I think Chika (CHICA!) is a Green Gal. (I hate the Japanese filter because is it yellow? Is it green? Is it bad eyesight?)

Which means Minami is our strawberry-colored ball of 💕love💕 since Hikaru is in love with her.

But why these outfits on the double date?

Chika had a green dress withthat red/pink cardigan, and Minami wore the green colorful sweater with the pink scarf and coral bag while the boys wore their colors.

And Chika has that green and pink scarf.

So what is going on with these girls?!

Make it make sense, Mary!

#my strawberry film #the colors mean things #so what the heck is happening with the girls? #the math ain't mathing #and the colors ain't coloring #I need answers!

hellooo ive also been following u since 2018 i was 14 then and im 20 now lmfao and ur one of the only ppl on tumblr i regularly remember to check the blog of bc ur art style has always been one of if not my favs across fandoms <3

omfg..... i know im only like a couple yrs older than u rn but U WERE SO YOUNG OMG??? AND NOW YOU'RE 20!?!?!? thats nuts???

BUT WAAAA YOU'RE SO SWEET ;___; <33 that means so much to me esp since i dipped in activity for a while there but i appreciate hearing that sm you have no idea 😭😭😭💛💛💛

#adrien replies #who are you kind soul..... pls... #my literal reaction doing the math made my jaw drop LMAO #but thats so cool knowing some of yall have stuck by me that long!! like whadda heck!!! #btw obvi not forcing anyone but if yall wanna talk- my dms are always open to vibe n chill #esp if you've been interacting w me that long #like chances are that i will likely remember or recognize ur url if youve been interacting w me for that many years #i see yall and i appreciate yall sm ;__; <3 #knowing that some of yall still check my silly little blog even tho i have periods of inactivity is so heartwarming..tysm.. #adrien doodles

This isnt a crazy statement but i still think that there should be better diversity on the life series. I mean specifically there should be more woman creators and creators who are poc.

Like 3rd life had ONE woman!!! WHAT THE FUCK?

Theres only ever been TWO non-white members of the life series! What????

Only 4/17 of the secret life members are women! Thats like 4 and a bit men for every woman! THIS IS THE SEASON WITH THE MOST WOMEN????

Like i know the gaming space is a bit messed up on this front but like cmon....

I dont think that the life series is like. Intrinsically bad or anything, but it would be cool if Grian/the team and such could take notice of these facts and help to change the server just a bit more.

#trafficblr #traffic smp #okay originally this post was only going to be about women and then i realised also how messed up it is that theres only two black #people on the server #fuck i dont even make posts like this like. ever. #but i feel like it would be really you know. COOL to get some more diversity in this particular minecraft gaming sphere especially #idk im trying to increase the diversity in the last couple of months in what i watch and listen to since i realise that its not good enough #and i realised these facts and im like. shit this isnt just like a me thing this is deep in our fandom #same goes with most minecraft series #heck i watched a random up-and-coming minecraft youtubers video today on a competition server. #not a single woman???? really??? #hey maybe if theres enough backing it would be worth like. sending an email or something idk #so long as people are polite about it ig #idk ive never really talked about this stuff before but its been bothering me #grian #grian critical #also sorry if my maths is just totally wrong idkim bad at it

[spacewives-in-spacetime]

You have to know that I LOVE talking math and I am used to people stopping listening after three words so - don't worry if this isn't anything for you after all but also please ask any and all questions <3

Without further ado: Addition and multiplication explained structurally as I understand them in as simple terms as possible

Do you know what a function is? - starting with the hardest part right off the bat but that's math for you 😅 So a function is like a recipe of what you do to things in one pot, named 'set' to return things from another set (so another pot). The sets could be anything, meaning there could be anything in either pot, even other pots. The things inside the set are called 'elements'. So a function takes an element from the first set and then returns an element from the other. You might know functions as like f(x) =x^2 or something but they can look very diverse.

Addition and multiplication are such functions that follow certain rules. We call them 'operations'. (I think we do that because they take elements from the same (not really but kinda) set that they return elements from but I might be mistaken. Never been good with remembering names.) So if we perform these operations on a set X, they will take elements from the set X×X and return an element from X. What does that mean? Well, in easy words it means they are functions that independently choose two (always 2!) elements from X and return one element from X as their sum/product.

And then the following rules apply for both addition and multiplication: (I am going to use the symbol * for either operation now)

They are associative, that is a*(b*c) =(a*b) *c (this literally means that within pure addition/multiplication the order of performing the operation is completely random - well as long as we don't change the order of the letters themselves. So by this rule alone, we can't start with the operation a*c because there is a 'b' in between but the choice between starting with ab vs b*c is free)

There is a neutral element. That is, there exists an element e in X such that e*a=a*e=a for all a in X. For addition this is the 0. No matter whether I add 0 from the left or the right to any number, I still get that same number. For multiplication this is the 1.)

There is an inverse. That is, for any element a in X there exists an inverse element b such that a*b=b*a=e, meaning if we perform the operation on a and B we get the neutral element. For addition, this is b=-a because a+(-a) =0 and for multiplication this is b=1/a because a1/a=1 (note the different neutral elements here). (also note that for multiplication in the real numbers we have to exclude the 0 here as it is the only number without an multiplicative inverse)

The operation is commutative, that means a*b=b*a. And THIS is the rule that basically tells us it is COMPLETELY random in which order we perform the operation AS LONG AS we have pure addition or pure multiplication.

Little capybara gif in between to take a breather:

[ID: gif of a happy capybara swimming with oranges. end I'd]

So what do we have until now:

There is no subtraction or division. That's a lie they tell you in school. Well, I mean, there is but those operations are covered in case 3 by the inverse. Like, really, structurally division and subtraction ARE NO DEFINED OPERATIONS. They are simply what we call when one of the elements we pick is the inverse of an element that would feel more 'natural' to pick. (hah, pun intended because the ones that feel natural to pick tend to be from the natural numbers) What do I mean by that? So if I asked you to give me an example for an addition, you would probably come up with something like 3 + 1 or 8+5. You would most probably not pick 1 + (-9), even though -9 is a real number, even an integer and something we should learn in school how to handle. At least if we get a good teacher. But 1 + - 9 is an addition on the reals! Same for the multiplication (1/6)*2, also a rather simple multiplication on the reals. (You may have noticed that I used the 'inverse' in the second place in the first case and the first place in the second case so obviously that is random, too. I could also do (-1)+(-3), bam : addition!) (btw I am putting inverse in '' on purpose here, because the inverse of the inverse is the original element again. So while we can say -3 is the inverse of 3 it is as true that 3 is the inverse of -3. Like subtracting 2 by - 3 would be calculating 2 +3, you know? Confusing? Yeah, that's why we like to ignore the existence of subtraction/division :))

With pure addition or multiplication - read with addition/subtraction OR multiplication/division there is NO SET ORDER TO THE OPERATIONS WHATSOEVER. This is because of point 1 and 4: point 1 says that for any expression with only one operation performed several times I can start with whichever one and continue until all have been performed. Left to right, right to left, from the middle outwards, jumping around - does not make any different. Point 4 says that in addition, I can randomly exchange the order of elements in addition, so really I can solve the expression HOWEVER I WANT (within the rules, of course, but the order is entirely random). Like that's what these rules are FOR.

Okay, but what if we mix addition and multiplication now? Then we get one (1!) extra rule:

5. For any elements a, b, c in X we have: (here now * is only multiplication and + is addition) a*(b+c) = a*b + a*c (distributive law)

So this is the only thing that tells us how to handle a mixture of addition and multiplication. That's why we have the 'multiplication before addition' rule - there just is no structure for doing it the other way round! You know?

Like, with the distributive law we know what to do when multiplying something with a sum. But there is no rule for what to do when adding to a product. So we first have to solve the product to get an element in the set of real numbers, because for that we know how to perform the operation. That's where the hierarchy comes from (I believe).

Funfact: in Germany this (multiplication before addition) is the only rule taught in school (or at least it was when I went to school in Germany). They don't have pemdas or whatever but 'Punkt vor Strich' which directly translates to 'Point before stroke' bc multiplication is one little point and division two little points. And addition is a Swiss cross and subtraction is a horizontal line. I have to admit it messed me up a little seeing as I very quickly used fractions / is also a stroke rather than a point.

And then the last casual and very obvious rule is 'brackets help us understand things so they are stronger than anything else'.

In conclusion:

there is no hierarchy between multiplication/division and addition/subtraction respectively because they are literally the same thing

order within the same kind of operation is completely arbitrary

you can always only perform an operation on two elements of your set OR perform the distributive law and this leads to the 'point before stroke' rule

Brackets are your friends and thus you prioritise them <3

I hope this makes sense, halfway?

If you want to look this up in more mathematical terms/clean definitions, then I have given you the rules for a 'field' and 'abelian groups' here. Also you might want to familiarise yourself with functions if you have trouble understanding this. I feel like getting what a function really is is THE entry step into understanding math. (but this is a personal opinion and I bet there are mathematicians who would fight me over that)

Because these are actually more general algebraic constructs and not just what happens in the reals when we add/multiply. They ARE the most simple examples of what you encounter in algebra imo but that might be because we are used to dealing with the reals/rational number from child age. Anyway, there are loads of different objects that work differently but with similar rules. Vector spaces and rings are lovely for example, if you want to have a look there. Or modules or algebras if you'd like it to be a little more difficult ;)

Have an image of some butterflies as a treat because you read until here <3

[ID: image of four butterflies on a shrub. end ID]

(I hope you like butterflies. I love them :))

(also, I really hope I didn't make any mistakes up there 😅 but more or less this is what Lilly meant by 'equal weight' of operarions)

holy fucking shit you are smart

i feel like this all makes sense (???) but i have one question: what tf is pure/not pure multiplication and addition? like, i understood everything but that just like messed with my brain 😭

i feel like this is such a good description of mathing that my brain is in shock lol

#math #mathematics #sry for the late response i went to sleep-ish #more like a nap in the middle of the night #do you have like a math degree or something cause you know so much what the heck?? #thank you so much for all the help!! #im rlly thankful that you took the time to explain this to me <3

Doing a big project which is why i havent posted tooned townie art for a hot minute but Heres some outfits i made on my corporate clash toon Roxie Swinkle-doodle.

I call the fits "Decimal Biter" and "GumBat Machine". I can admit it. i am a fan... of big goofy glasses and bows.

#toontown corporate clash #toontown oc #toonblr #the decimal biter outfit is mostly the Running Around Cashbot HQ n chilling thing #I also like to wear it as i invade cashbot buildings #im like pretending to go to work #except of actually working im committing workplace terrorism #ruining the math AND setting the building on fire #the gumball machine outfit is because i like gum and i was like oh HECK YES when i saw it in the shop #the rainbow glasses look SO CUTE with it

One of my favorite Terror bits is how when Jopson gets promoted everybody else reacts like :D

but then Jopson himself is just standing there like

*Dial-Up Noises* 

#404 critical processing error #u can literally see him trying to hurry up and do the math #as to whether this is crozier's way of saying his steward duties are never coming off pause #no but the fact that it clearly never even occurred to him that getting a promotion was an option like #i would kill to know who he thought Fitzjames was taking that paper to #my money is on Blanky or Hartnell #he probably spent the two seconds before james handed him the paper #trying to figure out how somebody impressed crozier that much without him knowing about it #but at the same time was fully ready to just go with it like Yay A New Lieutenant Heck Yeah Maybe It's Goodsir #then just intense elevator music #''you PROMOTE jopson? you promote him to third lieutenant? oh! love for father! love for father for one thousand years!''

Part of me understands that there are children in the world who have such a voracious appetite for learning that they will advance to college level when they're young teenagers, but another part of me wonders how many parents push their kids too hard to make themselves look good above focusing on what their kids need - time to relax, to build social relationships with people their own age, to explore non academic hobbies. I don't care what kind of complex mathematics you can do if you can't do laundry.
