so... Algebra

[Montehall]

does that fact that I recall almost none of it for my current class imply that I never satisfactorily learned it, or that it was so unused in "real" life, that I have never need it, and summarily forgot it?

[DAB]

i was told there would be no math.

i took, and passed, differential calc, and advanced diff. calc in college. never touched it again. :shrug:

[Stevedore]

I have a Master's degree in Mathematics. I think I used to enjoy it, but can't remember with any degree of certainty.

I did learn that a coffee mug is homeomorphic to a donut, if you want to talk about real-life uselessness.

I learned the color codes for resistors on printed circuit boards in school for my job, and I've never needed it. EVER.
my job now is a glorified, card-swapping, monkey.

I really don't understand why crap like this is "required" learning

I never quite understood why it was important to know the slope of a point. Let alone the fourth derivative of a cotangent. Some of it was interesting, but I don't remember any of it now; I've never used it. I have used algebra and trig though.

[Montehall]

Geometry. I've used Geometry.

[Thunder22]

Learning math isn't only about the numbers and the formulas, it's about the logic and making your brain work in different ways. Everything you do involves math, especially music.

[SQUIRMIN VERMIN 84]

Algebra got me introduced to math formula and all but I never used algebra
per se, just the derivatives of ohm's law and all the electrical power formulae
I use in projects. Resistor color-coding I learned as a kid in my dad's tv repair
shop and that was handy in my telecommunications job as the code equates
with cable binding coding. All in all it turned on a process of analytical thinking, for me anyway...

[CertInsaneC5]

I still use algebra, trig and calc. In spreadsheets. I have not picked up a calculator in years.

This is what I was taught in Navy Basic Electricity/Electronics Prep (BEEP) school in the mid-60's "Bad Boys Rape Our Young Girls But Violet Gives Willingly. Get Some Now."

The above mnemonic refers to the following colors and/or tolerance levels: Black / Brown / Red / Orange / Yellow / Green / Blue / Violet / Gray / White

Gold / Silver / No Color

It's amazing what you can remember, even if you haven't used it in over 50-years. . .

[CertInsaneC5]

You remember the mnemonic. Do you remember the values and tolerances that they reference? :Jeff '79:

[Datawiz]

Calculus 1, 2, 3, Advanced Math, Differential Equations, Thermal Dynamics, Fluid Dynamics, blah blah blah, and all I now use is Algebra. :yesnod:

Most of my programming jobs are business related, so the math is not tough. I've forgotten a lot of what I once learned. I was a math whiz. :yesnod:

And now I'm a DATA WIZ :rofl:

[GentleBen]

You remember the mnemonic. Do you remember the values and tolerances that they reference? :Jeff '79:

Actually, I do. Keep in mind that they start at 0 and go to 9 in orders of magnitude. The G/S/N tolerances were 5%, 10% and no tolerance specified/required.

The torus is a powerful thing.

I found that engineering school was the basis for critical thinking. Don't bring me a solution unless you have the analytical support for your position. IDGAF about opinions, and engineering judgment is just opinion until backed up with analysis.

As far as using math, I like to build stuff. Decks, cars, walls, whatever. So geometry is a basic need. I also like to dabble in statistics. Statistical math relies on basic calculus. Most linear mathematics I currently engage in is taken care of by MatLab or other software language, however, it is important that I understand the methodology, and thus the limitations, of such software languages.

[Entropy]

I use a lot of algebra, but I teach chemistry, so there's that.

I refer to calculus on a regular basis (and even use it in some labs) but not all the time.

It does go hand in hand with problem solving. Not in a "plug in A, solve for B" manner, but in how to dissect a problem and think through them. My students don't like the approach, but they learn the value soon enough.

[SteelCityBlue]

AS a chem major myself, this is why a small school chemist is often much better than a big school. No plug and play. You're the kind of prick that gives homework every other day as well, huh?

[Olustee bus]

Algebra was one of only two college courses I failed. I went back and passed it.

At one time in my Financial review jobs I used lots of algebra. Sometimes I would have to study it. It really helped. I was reviewing hospital rate increases and the impact on their budget. They would show one thing on the actual rate increases but a different thing on the overall budget. I would employ some algebra and call them on it. I enjoyed it.

:cert:

[8Up]

Math is a use it or lose it thing. I was really good in college, got an engineering degree. Now I can only remember the basic stuff as far as algebra and geometry and I got A's in both. I dont remember calculus at all. its the only class I got a C in all through college and I havent used it since. But at least I can tell people that I learned it once.

[Entropy]

AS a chem major myself, this is why a small school chemist is often much better than a big school. No plug and play. You're the kind of prick that gives homework every other day as well, huh?
Homework is only due once a week (it usually takes 2 to 3 hours to complete) but I give quizzes every week.

I make them write full lab reports every week as well and keep data in a lab notebook/

Most of my students transfer (I teach at a community college) and they need a good foundation to be successful in the rest of their classes.

[SteelCityBlue]

What are you teaching and how many students?

Is the Pie she ate round or square?, need get to the root of the problem.....:issues:

[Entropy]

What are you teaching and how many students?
I usually teach 3 different courses per semester. Course size is usually around 30 students, and I usually double up on at least one of the courses. So around 120 students per semester.

Courses I teach include:
Intro Chem - It's like 1 year of high school chem shoved into 1 semester.
Gen Chem - This is for your standard freshman course for chem, bio, engineering majors. 2 semester course and I teach both.
Intro to Organic/Biochem - This is for nursing and dental hygiene students. I also get some pre. pharm/med students who want a little background before tackling full blown organic chem.

There's some kids who might actually get into math if the problems were done like that. :funny:

antwan buys a kilo of smack for 100, he wants to step on it (cut it by half) and sell 1 oz bags for 20 each. what's his profit (assume he steals the creamer from momma's kitchen)? :dance:

1kilo = 2.2 lb

1lb = 16 oz

so we have 35.2 oz of uncut smack. step on it once, and we have 70.4 oz of cut product. times 20 bucks each = 1400 (the 0.4 oz is given away to a 'friend'). minus the 100 he spent, that leaves a profit of 1300.

here we have conversion from metric to customary, and lb to oz, and multiplication and subtraction. a decent problem.

close enough Cert, full marks.

Thanks Douglas. But you have huge rounding errors in that calculation.

One Kilo = 35.27396195 Oz. Stepped on = 70.547839 x 20 - 100 = 1310.95678. Shame on you. You should know better. And you never said anything about dipping into the stash. :D :leaving:
