@futurebird A long time ago (yes I am that old) I was taught how to balance my checkbook. Of course that technique assumes money only went into my checking account via manual deposit and only came out when I wrote a physical check. It is pretty much useless today.

That model of teaching was […]

I WILL NOT tolerate any of my former students wandering around in the world saying "nobody ever taught me how to do the taxes" NO. You will not be saying that. I'm not putting up with this. It's just percents and recipes.

(although, I'm glad I looked at the topic more closely, there is more to […]

And I do hope my students find applications for what they learn in my class, that mathematics permeates their world and informs how they solve problems.

But if all I could say is that all my students understand the difference between marginal and effective tax and how brackets are applied? If […]

@futurebird I think the inability to get marginal tax rates is motivated reasoning/propaganda. People purposefully don't get it for ideological reasons, then other people hear the tales and unthinkingly accept them.

@futurebird Back in the 2000s when I was active on LiveJournal, I do remember actually educating one of my LJ friends about this, and it was one of my proudest moments there. He was a pretty smart guy who worked in movie CGI in San Francisco. But the circles he moved in were pretty […]

@futurebird The thing is, I remember people getting this wrong even in the days when most people filled out a paper 1040 by hand. So they had actually gone through the calculation and they still didn't understand it. Now, most of them probably did this crucial step with a table lookup. But you […]

@mattmcirvin @futurebird

at every job I've ever had, someone would bring up all the bad-faith right-wing lies about taxes every time taxes were discussed in converastions at work. I encountered this at dishwashing jobs and software development jobs, at postal service jobs and community college […]

@mattmcirvin @futurebird Actually in the Netherlands when I was little, income tax was determined from a lookup table, essentially a multi-step function, but with tiny steps. Then they introduced the piecewise linear thing, the "schijventarief". And yes, explaining it was a challenge […]
