#mathematical operators

Rate your favorite logic notation

[elitist-asshole]

was it shortsighted of ed sheeran to start naming albums after mathematical operators? will we get an “integral” or “derivative” album? what about a “summation” (with the capital sigma, NOT a “plus”) album? square root? gradient? curl? or is he pandering to the non-mathematical masses and only doing the elementary school level shit? weigh in in the notes/tags i want to hear your thoughts tumblrinas

[bubbloquacious]

What mathematical operators would you think make for the best fuck marry kill discussion

FMK: addition, multiplication, exponentiation

FMK: powers, roots, logarithms

FMK: group operation, inversion, unit element

FMK: polynomials, differential operators, continuous maps

FMK: greater than, less than, equal

FMK: one, two, three

FMK: numerator, denominator, quotient

FMK: rings, integral domains, fields

FMK: categories, functors, natural transformations

FMK: reflexivity, transitivity, antisymmetry

FMK: fundamental theorem of algebra, fundamental theorem of calculus, fundamental theorem of arithmetic

FMK: prime numbers, composite numbers, units

FMK: algebraic geometry, algebraic topology, algebraic number theory

FMK: compact Hausdorff spaces, abelian groups, algebraically complete fields

FMK: axiom of choice, well-ordering theorem, Zorn's lemma

just found out about lambda calculus!

(beta reduction my love, please I must learn more...)

I don't think we should stop teaching kids things like long multiplication/division because there is value in being able to manipulate numbers and correctly carry out an algorithmic process, but I do think we spend way more time on it than we should (at least at my school).

I hate to sound like the 'we basically always have a calculator so what's the point?' complainer kid, but... we very much do have access to a calculator most of the time. So I think kids would benefit from less time cranking out arithmetic problems and more time:

Practising good calculator use

Learning to use things like estimation, inverse calculations, parity, and check digits to spot a wrong answer

Looking at a problem and figuring out which sums to do (we already do this, but there should be more of it and calculator use should be allowed more often)

This is more for younger kids, but taking the time to make sure they understand exactly what each operation actually means (this will make the above point easier because a sentence about sharing something out between different people will scream 'division')

Learning more about the properties of the different operations (which are commutative and which aren't, which are inverses of each other - maybe things like being able to cancel factors before you divide or how multiplying by a and then by b is the same as multiplying by ab, but I know some kids who would really struggle with that)

Problem solving and logical thinking

There's way more, but anyway I think it's less important for a kid to be able to do, say, 34 x 59 by hand than it is for them to be able to recognise something like 93 (accidentally pressing + instead of x) or 3105 (pressing 5 before x instead of after) as a wrong answer.

Mathematics in Daily life and Basic concept

[unopenablebox]

i can really tell when an academic has started trying to meet with vc firms about forming a company for the first time. because for a while afterward they’ll say things like, “you know, i never really appreciated how all the sentences you say have a clear and concrete referent. and the way you use verbs and nouns that describe particular events in the physical world"

same anon from right before, but.... könig is what? like 6'10 and built like a moutain. you're telling me that man *doesn't* like plus-sized people??? he most certainly does and jim boeven is dead wrong.

this, exactly.

also unless könig wants to get prosecuted for attempted murder every time he sticks it in, a little cushion seems likely. better safe AND ALIVE after a monster cock than sorry.

although, dying by königs cock doesn't sound so bad but my depravity isn't relevant here. ignore me

Time to start a wrestle with the mathematicians

[sacredmoonbeamtarot]

Sometimes it’s wild how I just do a little math and end up solving issues I stored way too long.

Never was much of a math lover until I realised it’s the language of the universe and it’s actually kind of healing. 🌘🧹

just saw a post about manipulation and the first thiing that came to my mind was manipulating a set mathematically

the plan is working

The problem with USAmerican recipes is that most of them call for ingredients that don't exist outside of the US and/or ready mixes. If I wanted to use a ready mix I would read the instructions on the box. Ergo functionally useless to me.

The problem with Brazilian recipes is that most of them are written as if they are just reminding you of how to make something you already know how to make. As such, information like how long to bake something, or what temperature the oven should be on, high or low fire on the stove, or even on occasion what kind of spoon (table or teaspoon) to use is deemed extraneous. Which is also functionally useless.

I end up using the Brazilian recipes while checking English-language ones for baking time/temp and verifying spoon sizes. And also just a healthy dollop of doing whatever the hell I want anyway, because in the end I am Brazilian after all.

GQ: Why do you like math more than Korean?

WT: Yes. I think that if you do Korean somehow, you can find the answer. But numbers, math, are so certain. So, if I'm wrong, I can openly admit it and say, 'I was wrong.' That's really great. (Laughs)
