Like, does it loop back around the digits or something, like a mileage meter in reverse?

1, 0, 9?

The following examples may help to clarify the difference between the new and old math.

1960: A logger sells a truckload of lumber for $100. His cost of production is 4/5 of this price. What is his profit?

1970 (Traditional math): A logger sells a truckload of lumber for $100. His cost of production is $80. What is his profit?

1975 (New Math): A logger exchanges a set L of lumber for a set M of money. The cardinality of set M is 100 and each element is worth $1.

(a) make 100 dots representing the elements of the set M

(b) The set C representing costs of production contains 20 fewer points than set M. Represent the set C as a subset of the set M.

(c) What is the cardinality of the set P of profits?

1990 (Dumbed-down math): A logger sells a truckload of lumber for $100. His cost of production is $80 and his profit is $20. Underline the number 20.

1997 (Whole Math): By cutting down a forest full of beautiful trees, a logger makes $20.

(a) What do you think of this way of making money?

(b) How did the forest birds and squirrels feel?

(c) Draw a picture of the forest as you'd like it to look.

I didn't say it was obvious. He acted like it was gibberish.

Yup, it rolls around in whatever base you're counting in, decrementing the next column by one (or adding to the bottom row of that column in the second 'old math' way he does it, which is probably the least straightforward).

Is it because I'm on a mobile that this is a blurry mess? Like it looks like it's really zoomed in or something.

Republicans are literally upset that Obama isn't engaging in nationalistic propaganda. You know who else liked nationalistic propaganda?

edit: For content, the bottom comment/addition on that link. It's a vintage one, I can remember it floating around email Fw:Fws in the late 90s, and it's insufferably smug about 'school in my day' with a dose of 'hippie librul teachers'.

From this lovely e-mail forward, I conclude that New Math loving ruled.

All of us that had reduced lunches weren't morons and would have been able to handle it (actually, I had free lunch).

Man, for how "progressive" this forum claims to be, you guys really look down on and think less of those of us that actually grew up poor. We're not the idiotic victims we're constantly made out to be here.

It looks horrible on my phone too. But on my desktop it's fine.

Edit: No wait, it's all horrible. Especially the whole "the smallest minority is the individual" stuff...because apparently the only way to truly protect the rights of minorities is to protect the individual right of straight white men to discriminate against them!

Probably not, people like that tend to retrench and dig deeper when presented with evidence and arguments that go against their worldview.

Just gonna highlight this for a minute 'cause it bugs the hell out of me.

Just because so many people have refused to back down when shown evidence of how wrong they are, does not mean we should give up and not tell them that they are ill-informed. I used to be a loving idiot in regards to politics. I didn't so much look things up on my own, I just sort of parroted what I was told by my parents. I at one point believed the reason the economy was in the shitter was because the automobile unions had hosed the country over because gently caress everybody else but them. Do you know what made me change my mind? What made me stop and re-adjust my world views?

A friend of mine stopped me, and told me that I was loving wrong, and then proceeded to explain to me *how* I was wrong. I didn't like it at times. At times it made me feel like he thought I was a loving moron, but he always told me that he still liked being my friend, I was just wrong about this, and no I'm not a moron, I just was ill-informed. That if I was truly an idiot he wouldn't want to be my friend.

He helped me find myself, and find my drive to research and learn about politics instead of just parroting other things that my parents or talking heads said.

It's an example of the problems of NPR reporting that they think research hasn't been done in this area. To repeat what I posted way earlier in the thread, the concepts discussed in the posts above, as well as in the NPR story, are neatly captured in politeness theory, a communication science model that's all about persuasion when self-identity can be threatened. I haven't had the opportunity to study the theory in detail yet, but it's well-established and popular in the discipline, so it's going to be at least somewhat effective. I'm really looking forward to reading up on it so I can contribute some processes of effective forwarded message refutation to the thread. ARE COMIN TO STEAL MY GUNS!!!!!!!!!

I, uh, what? I'm not a part of the forum gun rights brigade. NPR science reporting is just really shoddy sometimes- they tend to cover individual hot theories or theorists, rather than meaningful work, and, as above, tend to miss interdisciplinary connections. That face threat issue and self-defense phenomenon have been documented about all kinds of health scares, especially those involving children, for years.

It's from a goddamn movie called Never Back Down. It's a work of fiction aaaaaaaugh. I'm about to start posting video links in response from The Matrix about how this one guy fights off an IRS agent with his elite army training.

On the other hand, it's nice when people admit the American Revolution was more about taxes than FREEDOM

You should do this. Just rip a fight scene from Matrix off YouTube then rehost it with a title like "IRS Agents vs. Elite US Agent"

Because clearly the only thing different from the taxes that fueled the revolutionary war and the taxes we have today is that people are pussies today. Clearly.
