# More Reasons to Learn Algebra

Here are some more people responding to Andrew Hacker’s article.

I’ve included a link and my favorite quote.

Rob Knop at Galactic Interactions.

Liberal arts education is to make people into good citizens, not into good workers. They are to acquaint you with the intellectual achievements of humankind. That is why we read the

Iliad, why we watch a performance ofHamlet, why we learn about the history of ancient Greece, and, yes, why we study algebra.

PZ Myers at Pharyngula.

We live in a technological society. Not learning algebra in the public school system means those kids will not be prepared, will not be qualified, to do

anythingin science and engineering. I’m serious: if you don’t know algebra, you can’t do basic quantitative chemistry, and if you can’t do that, you can’t do biology. At all. Not the molecular/biochemical/bench side, not the ecological/evolutionary/field side. You can’t do physics, that’s for sure. Forget math and statistics. If you’re not capable of grasping statistics, forget psychology, too.

Dave Schuler at the Glittering Eye.

I’ll go farther and hazard a guess that poli sci, like the other social sciences, is much more empirical and quantitative now than it was then and that Dr. Hacker would be hard put to earn a doctorate in his own field nowadays.

Economists have shown that cognitive skills–especially math and science–are robust predictors of individual income, of a country’s economic growth, and of the distribution of income within a country (e.g. Hanushek & Kimko, 2000; Hanushek & Woessmann, 2008).

Anna Nagurney at RENeW.

We need more problem solvers and they need algebra.

A patient who understands graphs and inequalities will have a much better control of their health than someone who has trouble with even basic arithmetic. This is not a case of mathematics being a prerequisite for a job, the usual argument for numeracy. This is mathematics making a difference in your own health.

My favorite response is from Alexandra Petri at The Washington Post.

When my friends call me late at night complaining about how hard it is to eliminate exes from the equation, we never turn out to be talking about the same thing.

Jen Chung at gothamist

On that note, here’s commenter Ben: Is English literature necessary? I never ran into Moby Dick during my career. Is Gym class necessary? I never had to do a pull up. Is Physics necessary? When was I called upon to do vector analysis? Is Biology necessary? I think only French Chefs have to dissect frogs in their careers. It must be tough to teach. What’s the point. Walmart has all the stuff we’ll ever need. Supersize that happy meal. We’re just turning into a bunch of consumers anyway, lets just stop pretending that we need to know anything.

Evelyn Lamb at Scientific American.

Few pre-college math teachers majored or even minored in math, and until more teachers do, improvements will be hard to come by. Ironically, it seems that people who have mastered “useless” algebra and other higher math topics tend to get jobs that pay more than middle school math teachers earn. I have the utmost respect for people with math degrees who choose to teach in spite of the poor pay and discipline problems, but few people make that choice. Math education needs help, but Hacker’s suggestions throw out the baby with the bathwater.

RiShawn Biddle at Dropout Nation

The advent of the Internet and the emergence of quantifiable data is making math skills critical to many white-collar professions; marketers and public relations staffers, for example, have to understand the arcane aspects of statistics in order to analyze data on ad campaigns, while reporters and editorialists need stronger math skills as well.

Rollin Bishop at Geekosystem

To say that we are failing and need to do something about it is absolutely correct. To say we need to remove it from our path as a hindrance rather than overcoming it with improved teaching methods, enhanced mathematics programs, and funding in general is a mistake.

My own humble contribution.

If you don’t know a subject, how do you know if you couldn’t use it?

**Update**:

Here are some more. A recurring theme is that Algebra should be required but we should probably rethink how we teach it.

Dan Meyer at dy/dan:

The more interesting question is, “How should we define Algebra in 2012 and how should we teach it?” Those questions don’t even seem to be on Hacker’s radar.

When students say they have difficultly with algebra, that’s usually not the entire story. Typically, that means they have also trouble with arithmetic. There’s a reason why the ability to do long division is correlated with long-term mathematics performance: you have to master the basics.

Ilana Horn at teaching/math/culture

Hacker is correct that we are not teaching enough children meaningful mathematics in schools. The problem, however, is not Algebra. The problem is Algebra as Usual.

My girlfriend is a fine artist, with an MFA in sculpting from a school . . . in New York City. Earlier this year, she was the recipient of a month-long artist residency in Taiwan where she put together an outdoor installation in knitted recycled plastic as part of an exhibit on environmental themes. She has a fairly high proficiency at math . . . and this gets used routinely in her career. She has to estimate volumes of complicated shapes she’s planning to put together, so as to procure materials . . . She has to do calculations with money so as to set budgets . . . She has to estimate time for projects that might last many months. At some point she generated a calculation for people, time, and material to cover the Eiffel Tower in tiny crocheted plastic leaves (a long-term goal).
