Calculus Made Easy, by by Silvanus P. Thompson, 1910. Full text available online.

Love this book. I read it after already learning calculus, but I learned a lot about how to teach a complicated subject in an approachable way.

Fuck the way media talks about “child prodigies” and “geniuses” especially in fields like music and mathematics.

Like they are gods whose level of understanding we could never reach.

How come we rarely hear about all the people who started young and then fizzled out? How come we never hear the stories of people who started late in life and made a huge difference.

Why do we only hear about their natural aptitude and not the hard work and misteps they took to get there.

For gods sake…

Terry is just a guy!

this is also why you can't get into some higher maths degrees if you're over a certain age. Universities are only willing to invest in prodigies, or potential prodigies, so if you missed opportunities growing up or you go into tertiary education later in life they basically treat you like you're an idiot (and god help you if you're a woman as well).

…you can’t “call someone out” for beliefs they no longer hold. that is called digging up irrelevant dirt as an excuse to harass and ostracize someone. i can think of literally nothing more transparently malicious

[proudfreakmetarusonikku]

if people can’t change their beliefs, are we all meant to just fucking die the second we make a wrong decision? it’s stupid and unsubstainable

What do you mean Ada Lovelace is Lord Byron's DAUGHTER

[mathematicalme]

Nah, nah. Her mother hated his guts and instilled in her a passion for science out of fear she might turn out like her father. And while you can hardly say she was like Byron, she did accumulate huge gambling debts through the belief that she could game the system.

The 9-Year-Old Taiwanese student problem

It was reported in 2020 that this math problem was given to 9-year-olds in Taiwan. (No, they didn’t find it easy.)

It may seem hard, but if you take a few minutes to have an insight, you can solve it pretty quickly.

Each letter represents a different numeral. Solve for each letter.

this is cute

[taking-a-break-2022-deactivated]

This is amazing

[johnnyjoestarrelatable]

you weren’t a “well behaved” child you had anxiety and were terrified of conflict

[johnnyjoestarrelatable]

“a pleasure to teach” on the report card meant obedient to a fault, a constant need to be perfect to keep “a pleasure to teach” on the report card, realizing you weren’t as perfect a student as you thought when school got tough, and your perfectionism and paralyzing fear of “getting in trouble” is so deeply ingrained in you that you procrastinate everything because if it isn’t perfect, you shouldn’t try at all

[mathematicalme]

how dare u call me out like this

[balaclava-trismegistus]

"Are you more artistic or scientific" science is art and art is science bitch

[balaclava-trismegistus]

"this! im both artistic and scientific" no shut the FUCK up you don't get it

There is no difference. None. Science and art are both fueled by passion and romance. They are cycles of understanding, intimacy, and expression that have no beginning or end, that sustain one another in a wheel. Without artistic passion there would be no science. Without scientific understanding there would be no art. They are the exact same wonder and amazement with the world around us expressed through different yet interdependent media.

'im gay i cant do math' shut up shut up your ineptitude for mathematics has nothing ot do with queerness. math and/or science gays including space aces are an extremely well documented phenomenon. you know what absolutely none of the gays can actually do? understand economics

Plus Alan Turing does not deserve this

Why was math your favorite subject in high school? What’s so interesting about it? It’s a pain for me 😓

I like mysteries, trying to find the solution to a problem. I've always seen math as a challenge and never accepted to be defeated. I love the high it gives me as if there's nothing I can't do if I really put my mind to it.

Yeah it can be a pain, but you are smarter and braver, own it and make math your bitch 😌

Exponential Growth & Decay

When a number increases by the same amount over a series of periods of time this is exponential growth.

When a number decreases by the same amount over a series of periods of time this is exponential decay.

Powers and Roots

The roots of n are

√ n & - √ n

[mathematicalme]

Multiplying & Dividing Directed Numbers

When the signs of the numbers are the same, the answer will be positive

When the signs of the numbers are different, the answer will be negative.

Fractions

Finding a fraction of a quantity

In maths, ‘of’ means multiply, so multiply the fraction by the quantity.

Adding & Subtracting fractions

Convert the fractions to be equivalent, then add or subtract the numerators.  Convert the result back to its simplest form

Multiplying fractions

Multiply the numerators & the denominators

Dividing fractions

Invert one fraction and multiply the fractions together
