lol we just use base 10 in school

well ya
i have proofs right no. oh dear lord kill proofs

this is from the sixties, when the way addition was taught was being changed. This is all much easier than he makes it seem, and octal (base 8) is not taught in elementary school or middle school, and is usually avoided in high school, unless you`re doing computer programming, and even then it is rarely used (at least in America).
Male 901
Now instead of 4 in the 8`s place you got 3
`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!

Base 8 was big in computer programming. Time was, everything had to be programmed in binary (base 2) to write the simple number 9 in binary you have to write 1001. That takes up A LOT of space. so by using base 8 you could use about 1/3 of the characters to say the same thing.

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

Female 224
the first one was easy just not the way he explained it
i never heard of base eight

Hey guys, why do you feel so insulted? First of all, noone called you stupid, point was that you CAN understand that, but never leaned how to do it. Second, my best friend went to USA to finish high-school and only geeks and nerds knew how to do fractions. Maybe it`s just case study, but I guess that educational systems do differ. Third, yup, you`re right, if you`re 21 and speak 3 languges, and english is your fourth, you mustn`t make any mistakes. And at last, should I even comment? Maybe, just maybe, kids start elementary later in other countries?! And still, it has nothing to do with amount of knowlege they have at same age in my/yours country. So, you have 3rd grader that is 8 and still has trouble to read/write, and in my country you have 1st grader that is 8 and does it pretty good. Hmmm... retarded? Don`t want to start no patriotic argument, I`m sick of it (living in Balkans). Personal is OK, but patriotic...not so much.

I say ... No

For those wondering what`s `new` or why america might be so concerned with basic subtraction:

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.

Female 488
i`m not a math nerd (i hate math) but i have a friend who was OBSESSED with bases, so i actually understand that concept. yay.
Male 384
catchy...
Male 429
Binary, hex, and other bases are used in computing and mathematics a lot. They are useful in some cases, but more or less useless in everyday life. I somehow doubt they actually teach this to elementary school kids.
Male 87
i agree with everyone who says base eight is pointless. if you don`t understand it...i wouldn`t lose too much sleep. weren`t the mayans the last people to not use a base 10 system? i heard somewhere they used a base 7.....shows how useful that stuff is....
Male 447
:l wow im soo confused
Male 121
XP you screwed up your binary counting, you skipped 1011 and 1110.
Male 244
wow base 8...whats the point?
Female 663
The Japanese think of things in terms of 10.
The Japanese lead the world in math skills and applications.
I think I`ll stick to what I know.
Male 3
Octal (Base 8) has many applications in Computer Science, though to be honest Hexadecimal (Base 16)is often less cumbersome.

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

Male 3,431
What real world application is there for a Base Eight System?

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.

Male 679
I was amused.

Although he should have done it in hexadecimal.

Who`s on 8th base?

"That`s the way I was taught to subtract. And with the bases it`s actually pretty simple. base 10 is how we count.. you count to ten then start over in base 8 you count to 8 and start over. i went to a Montessori school and we were doing this type of stuff in second and third grade with an abacus. no joke."
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
Male 1,420
"Base 8 is so drating pointless. Use a damn calculator or ask someone smart and keep saying you don`t get it until they do it for you." settle down already. just because you cant do math, doesnt mean you need to condemn those who enjoy it.

"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.

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

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.

"Nothing new about that math near as I can tell. Same math I learned in grade school 30 years ago."

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

Male 11
First of all, that base 8 was easy for me, and I`m 13 and in 8th grade. 8 in base 8 equals 10 in base 10 which means that really, in base ten, all 11 means is that we have 1 base and 1 left over. Therefore 11 in base 8 is the base, 8, plus 1, which equals 9 in base 10.

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.

Female 576
I think I`ll go w/ base 10.
No need to go w/ eights when we`ve been using 10 since we started counting.
Male 522
0,1,10,11,100,101,110,111,1000,1001,1010,1100,1101,1111

manar, yes we are dumb americans, we are well aware that our educational system sucks. but come on. teaching binary in third grade? id only buy that if you were japanese.....maybe.
Female 1,158
Wow.

I hate bananas.

Male 196
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.
Male 437
so true it made me cry. if i knew my old math teachers e mail i would send this to him (i never learned base 8 tho WTF is that?)
Male 1,386
whats the point of teaching base 8 anyway? its completely useless :P

Male 901
The main question is: Why learn base 8 when it`s the same thing as base 10 only not used?
Female 1,589
WTF base 8? WHY?!
But I`m sure if I learned in song when I was little math would have been much easier for me. ^___^
Male 30
That isn`t too confusing. I haven`t a clue of what base 8 is, but I do partially understand... now where is the person who spams "I`ll stick to 1st and 2nd Base"?
Female 441
Thats the way i wuz taught i dnt think i have eva seen a different way... its really simple
Female 362
What the hell are they having kids do now?!? What is the point of base 8 any way?
Male 287
Male 345
lolwut

that was a cool song

This method is better for doing it in your head than writing it on paper, if you have to write it out then do the normal way.

273 (+100)

342
343 (+70)

342
342 (-1)

100 + 70 - 1 = 169

Male 1,228
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.
Female 1,492
what the hell? and i`m looking at broadwaylove`s explanation and i`m like...seriously...stop lying to me...what.
Male 317
is it real? i don`t get it. I can calculate in base 16 no problem, and i can do multiplication in any base. But i don`t understand why teaching it to the kids. As woot45 said, base 8 is pointless.
Female 1,398
Base 8 is so drating pointless. Use a damn calculator or ask someone smart and keep saying you don`t get it until they do it for you.

Female 52
im gonna give my sis a calculator...
Male 108
Base 8 is for people who lost a couple of fingers or thumbs. Poor buggers :-(
Male 1,406
Base 8 isn`t as hard as it looks, it`s saying it at 2x the speed that makes it hard to understand.
Male 330
So the point of base 8 is to accomplish... what, exactly? All I can see is getting different answers to the same problem.
Male 46
i just use a calculator.
Male 1,371
tom lehrer he`s the guy who wrote the elements song xd

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

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

Female 428
Ewwww, math.
Male 1,497
base 8 is for people who cant count to 10 in the 1`s place :D

god damn stop posting math problems and how to do them, we arnt retarded!

for those of you confused about bases. Here`s a video that might help
Male 4,745
New math?!? Well, I learned it that way in the 70`s so it can`t be that new.

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...

Female 139
that made perfect sense except for the base thing
Female 455
I`ve never heard of base 8 or base 10 in my life...
Male 204
umm....WHAT?!?!?
Male 1,275
In 20 years there will be anougher song and that figur 8 will be the simple way. :-/
Female 76
wth do you need to learn how to do it in base 8? keep it simple!
Female 3,574
... even tho I hate math D:

I <3 that guy!

i hate maths. but im in the top group. i hate it. O.o
Male 91
For thoughs of you with no clue, base 10 goes:
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)
Female 115
why base 8. i understand. but WHY???
Male 2
There are 10 types of people in the world, those that know binary and those that don`t. :)
Male 1,114
Ok, who cares HOW you figure it out, only matters that the answer is right...
Female 532
Eh, I don`t really care about the other bases...

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

Male 254
thanks BroadwayLove i sort of get it now. I know base 2 from computing class (binary) and learnt how to do the differnet bases but forgot. Thanks for the reminder.
Female 251
Female 187
to understand different bases:

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.

Tom Lehrer is amazing.

What the hell is this base 8 crap?
Male 713
Oh, I later read on it wasnt. Sounds like him though.
Female 118
The first part I got, but the base eight gave you a different answer. Me thinks he skipped a step.
Male 2
The concept of base 8 is that anything that in base 10 equals ten is 8, if you have 11 in base 10 youll have one group of 8 for the group of ten and then the 1 left over
Male 713
Is this Arlo Guthrie?

yay i love doing different bases! hex is my favorito!
