well ya

i have proofs right no. oh dear lord kill proofs

`cause you added one, that is to say 8 to the 2

But you can`t take 7 from 3 so you look in the 64`s

From the 3 you then use 1 to make 8 1`s

And you add those 1`s to the 3 and you get 1-3 base 8

or in other words in base 10 you have 11 and you take away 7

and 7 from 11 is 4!

I`m with you so far!

Today we use Hexidecimal (base 16) which is absolutely scary, but it saves even more space.

i never heard of base eight

The song is from the 70s.

The guy is Tom Lehrer, well worth a look, see wikipedia. Dry, dry songs about current (at the time) events. Taught at Harvard. I heard a story he invented gin jelly to get around a campus ban on alcoholic `beverages`.

Anyway, what happened was they changed the way people were taught to do maths from the ways he mentions at the very beginning to the way everyone does it now. My impression is that the old ones were quicker but the new ones work by understanding what you`re doing.

I gather there was something of a crisis a parent (and some teachers) were even less able to do their kids maths than they normally are.

AFAIK the only use for base 8 is to show you get the general idea with base 10 and base 2.

The Japanese lead the world in math skills and applications.

I think I`ll stick to what I know.

Base 10 is too clumsy to represent with binary. :)

We may as well study a system based on the square root of (i). A base ten system is functional, simple, and unversally accepted.

Granted we use a Base 6 System to keep time, but that`s cumbersome and nonsensical it`s self. That certainly isn`t new math.

Although he should have done it in hexadecimal.

i went to a Montessori school too, but a few years after you... so we werent actually taught it. but i do blame that school for my ease in math

"Whats so new about this math ? It is the same math i did in the eigthies. And base 8 i learned while in third grade (with binary and hex). So where is the joke ? This is elementary stuff."

see, these were targeted at people like us... who would understand what it means, and not think "wtf is base 8?!?" it wasnt intended to sound hard, it was intended to sound like were teaching kids the complicated way.

In my country kids are taught that "12teen-year-olds" are actually called 12 year olds. That`s the way our educational system is"

-------------------------------

Besides, nikkia, if you have 10-year-olds in third grade, they`ve already flunked a couple of times. In my country, third graders are 8 years old.

Sorry, you lose. Move quickly and quietly to the retard section.

This song is even older than that. It`s from "That was the year that was" by Tom Lehrer, and was released in 1965!

Second of all, xp, the reason that the math is the same that you learned in grade school is because the audio track to this is from 1965, someone just set it to video.

No need to go w/ eights when we`ve been using 10 since we started counting.

and so on...

I hate bananas.

In my country kids are taught that "12teen-year-olds" are actually called 12 year olds. That`s the way our educational system is ;-)

But I`m sure if I learned in song when I was little math would have been much easier for me. ^___^

342 (-1)

100 + 70 - 1 = 169

I do it backwards, whereas instead of going right to left adding to the right to get a high enough number to remove the below from the top, I add to the bottom number whatever it needs untill it reaches the top number and there`s the answer.

am i the only one that added the solution and the second number and did not get the first? i don`t get it xd

Oh...my...God... It`s so simple! Can`t believe most of you can`t do it! It`s just sung really quickly, so it seems complicated. In my country, 12teen-year-olds could do it. That`s the way our educational system is. And fractions - children learn that in 3rd grade (10-year-olds).

Well, most education systems must be similar. My friends daughter is in 3rd grade and is learning fractions.

As for the base 8, base 2, base 10 etc., in most cases, you don`t need to know it (Well, you need to know base 10...). If you want to learn it, there are a ton of great sites out there where you can learn. If it doesn`t interest you, move along. Nothing to see here...

0 1 2 3 4 5 6 7 8 9 (ten numbers see?)

base 8:

0 1 2 3 4 5 6 7 (10 11 12 13 14 15 16 17 20)

But yeah, you can definitely hear the Arlo Guthrie STYLE in this :-)

It made me giggle.

base ten means that every time that you move over a number (like lets take 123) the number that is ACTUALLY multiplied by ten each time. so rather than writing 123 1`s we say we have 1 hundred two tens and 3 extras.

____ ____ ____

10^2 10^1 1

now that is base ten

In base eight, instead of going by tens you go by eights. Below I will count to eleven

0 1 2 3 4 5 6 7 10(8) 11(9) 12(10) 13(11)

to write 123 in base 8 we will need more spaces

________ _______ ______ ____

8^3(512) 8^2(64) 8^1(8) 8

we don`t need anything in the 512 slot. but we put something in the 64 slot because 64 is less than 123. We get

1 ___ ____

123-64=59

8 goes into 59 7 times with a remainder of 3. So your answer is

173.

I hope I have helped you to understand.

No, it doesn`t even sound like Arlo. It gives the guys name twice in the video.

temporary never they express not storcono, WHICH BECOMES..... The trees of the trowel of the beginning and the cliff that the

boneses extract the summary that my provisory he storcono never

expressed.

But I would like to learn the concept of base 8...
