The secret to doing math in one's head is knowing how to redefine an equation into something simpler.
Take the conversion of Celcius to Farenheit, for example. Instead of remembering that 1.8 times crap, try this:
Take your base Celcius and double it. Then take a tenth of that and add it to 32. Return the difference back into your previously doubled number, and viola!
Absolutely correct. I am a computer programmer and doing math(discreet math) practically everyday is how I earn my daily bread! :) So right on! Math rocks!
Math itself isn't man-made, it just takes man-made theories to explain it. And what is to say what is or isn't perfect in the scheme of things, especially in math which is such a massively open ended subject its like saying how long is a piece of string.. Concepts of math are different and were throughout ancient earth.. but all the anceint civilisations who had a high knowledge of math had their basis on addition, substitution, multiplication and division from which all math stems from.
I used to learn music with a Recorder (you know, those anoying wooden flute things) Now, a recorder makes this anoying sound, and NO real musician uses a Recorder.
There is a precious, precious amount of time when kids will absorb anything you tell them, this time should be used to it's full advantage, not wasted on skills that are fully intended to be thrown out and replaced with new skills when they get older.
These new maths algarithms are too big and complicated to do in your head while calculating how much change you'll get in a shop. They serve only to waste time. And an entire textbook that teaches complete dependance on calculartors is just... it's almost like GIVING people a mental crutch. If I had to rely so much on a calculator I'd never be able to do animation.
The new cash register girl at work can't add 70+50. she needed a calculator. Eck! She laughed and proclaimed that she didn't like math, like she should get a metal for it. Baby sign laguage is a great example of for kids not adults. Its not normal sign language but just as difficult, but for babies.. WTF?
I don't know which is scarier; an adult who can't do simple maths, a person who proudly proclaims their ignorance like it's a good thing, that this person has a job behind a cash register, or that kids in the most powerfull nation on Earth are being taught stuff that has absolutely no relevance to adulthood.
There's a strange idea in general where people try to teach children to be children. They... they teach then rules that do not apply to adulthood. In the old days it was things like "speak when you're spoken to". or "if you do this or that the boogyman will get you".
OK, I've seen about half of that video. Allot of the new algarithms seem to be the mathomatical equivalent of a Rube Goldberg invention. It's like they just made things complicated and time-consuming for no reason other than to make things more complicated and time-consuming. I mean, these kids are going to GROW UP, right? Do they really want them to grow up and draw all those diagonal lines when a cash register breaks?
I think only girls should be taught how to do math but only boys should be taught how to write. That way, we'll always appreciate each other...no matter what happens. lol. Sorry, that was my "deep thoughts" moment for the day and I couldn't resist.
lol. If you girls weren't allowed to learn how to write it would take a lifetime to learn math. It sounds like a sci fi story. :) A society that slides back to the iron age because they forced that way of learning on the people. but a few women would be in a hidden village writing and doing math. Math amazons.
Thanks those were great. I love how he asserted once you learned the conceptual method you would just understand the traditional method after that. <poof> magic math learning. p.s I think abnormalfunc meant 4.5 billion (earth age), maybe?
In a country where 24Billion equal 6000 (years), cosine is what you get for a high interest loan, and Florida votes don't count for shit, do you really expect anything more?
We're still measuring stuff by some long-dead king's body parts.
We're still measuring things based on roman wheel ruts. Instead of learning the metric system we consider teaching our children base 12. Not allowing children to learn math in a way they can be efficent and feel confident will affect our world negatively in the future.
I'm sure you knew this, but when they made the first talking Barbie doll, one of the things she said (aside from "Let's go shopping") was "Math is tough."
*slaps forehad* GAH.
Websnarf did a video on the "new math", and I couldn't agree more. Traditional long division and multiplication techniques are fine, faster, and the new math doesn't really explain the concepts any better.
Barbie is a pocket version of a blow up doll. they should have just given her 2 slots. One for cash and the other one having to do that birds and bees speech thingy. My niece has bratz. (one was in a video of mine) They're revolting. If you pull their string they say "I ain't need no learnin ift you axed me."
I STRONGLY disagree. I think girls *shouldn't* be allowed into ,the elementary grades ... and on up thru college. They should kept from aquiring any knowledge whatsoever. They should be taught to be compliant and grateful and to never speak unless spoken to. I can't stand the thought of having a WOMAN challenge my childesh arrogance and putting my tender male ego AT RISK.
when I was younger I was addicted to math, but I forgot it all now : ) and I agree we should all at least know the basics, how can you live without them.

I can take a random number...oh, say...
314 degrees Celcius
and get
597.2 Farenheit
With little trouble.

Math is man-made. It isn't perfect, e.g., x divided by 0, i, and 1 = 0.99999...
If we found an intelligent race of aliens, they would probably have a different concept of math.
