I'm not here to tell anyone how to parent, but my 11 year old finished 10% of precalculus this morning, because the alternative was cleaning her room. I think we could get a unified field theory if I asked her to mow the lawn, but unfortunately it's snowing today.

This is mind-boggling:
"“Of those who demonstrated math skills not meeting middle school levels,” the report found, 42% reported completing calculus or precalculus."
How can they be expected to even begin understanding calculus, if they haven't mastered fractions?

in fact i think the main thing i would do differently is recommend some youtube channels and Stroud for general purpose review, since one assumes an autodidact is either very rusty or never learned high school math. i would also cut precalculus. i do not believe in precalculus

There are times I suspect my precalculus book is trolling me. Then there are times I’m certain that it is (listen man, if I’m ever in charge of analyzing the height of a gargantuan SpongeBob balloon, then we can all breathe a sigh of relief)

Ok so the world is actively falling apart and my mom has cancer and I’m terrified 23+ hours of the day (lol I’m counting nightmares), but fucking A I spent 20+ hours on math this weekend and got a 93 on my first precalculus quiz and I feel like throwing a GALA

Nostalgia can be an incredibly beautiful and powerful feeling. It can come from a song, a movie, a place, or even just a smell. Unfortunately, relearning Trigonometry at 43 years old for my Precalculus class is not giving me any nostalgia.

Math nerds of the atmosphere, kindly check out my brother’s open source collection of free math books, ranging from elementary to precalculus level.
Years of work went into these openly available resources, low-key aiming to subvert a monopolistic & overpriced academic publishing industry.

It’s been a hell of a year. I got a job who consistently wouldn’t pay me, had a stalker for a minute, but I also got to take algebraic geometry, something I’ve been waiting to do since I took precalculus, so suck it Jahrome

I am a math professor. ChatGPT has several times given wrong answers to Precalculus questions. Humans have nothing to worry about.
