So... how good is your math skills?

i also got to 9, but by rethinking it, it should be 1. 2 x 3= 6 and 6/6 = 1

You have 6 apples and 2 classes with 2 boys and 1 girl.
How many apples do each person get?

nice one Cassie. almost had me there.

Post by **CasKru** » Fri Jul 06, 2012 8:44 am

But I also say it's 9

Hilux 1 · Post by **Hilux 1** » Fri Jul 06, 2012 8:54 am

where is the math teachers? maybe i"m over thinking it? but i would read it as 6 devided by 2 times 1+2(wich in my oppinion should be done first) and that give you 2 times 3 = 6. then you devide 6 by 6 and the answer is 1.

Where is the math guru's?

Hilux 1 · Post by **Hilux 1** » Fri Jul 06, 2012 8:57 am

in my opinion the answer would have been 9 if it was written : 6/2 x (1+2) = 9

There are 6 Mice, where always 2 mice become one pair. One pair gets 1 male mouse and 2 female mous offspring. How many offspring do all mice together have?
6 mice, 2 make a pair, so 6÷2=3. Offspring 1 male, 2 female (1+2)=3. 3*3=9

I'm also getting 6/6=1

My rusty math skills remembers the following - you should always do the calculation in the brackets first - and then work from left to right - so that would be:

6 divided by (/) 2 times 3

So that is 6/2 is 3 and 3 x 3 is 9...

Post by **CasKru** » Fri Jul 06, 2012 9:18 am

Okay... according to me using math rules:

6/2(1+2) = z
6(1+2) = 2z Multiply by 2
(1+2) = 2z/6 Divide by 6
(1+2) = 1/3z
3=1/3z Multiply by 6
9=z

SO thats where my maths went for sour grapes at school. i read the sums wrong. Thanx Cassie. nou sal ek myself nooit kan vergewe nie.

Post by **CasKru** » Fri Jul 06, 2012 9:28 am

Dit is nie te se ek is reg nie maar soos ek dit het:
Orde van bewerking
Hakies
Eksponente en vierkantswortels
Maal en Deel
Plus en minus
Links na regs

En volgens daai reels is dit heel maklik en vinnig
6/2(1+2)
6/2(3)
3(3)
9

ek het hom ook so eers gedoen, en toe bedink ek my self weer heel in n ander koers in.

ThysdJ · Post by **ThysdJ** » Fri Jul 06, 2012 9:52 am

Jy moet eers die maalsom doen, dan die deelsom... dan is dit 1.. as jy eers die deelsom doen en dan die maalsom dan is dit 9 ....

Skryf hom in die 6 oor 2(3) (breuke) notasie wat dieselfde is as 6/2(3) dan werk jy hom uit..

6
-----
2(3)

Dis hoe ek dit ook gesien et Thys. Dankie.

ThysdJ · Post by **ThysdJ** » Fri Jul 06, 2012 9:58 am

Hang af of jy PEDMAS of BEMDAS gebruik om die antwoord te bereken... Al twee antwoorde is reg..

Post by **CasKru** » Fri Jul 06, 2012 10:11 am

Volgens my is 9 meer reg as 1

Ek persoonlik maak oordentlik gebruik van hakkies juis om so iets te vermy. Kyk die verskil en hoe maklik weet mens nou:
(6/2)(1+2) en 6/(2(1+2))

6/2(1+2) = ?

Applying BODMAS

6/2 x (I+2) = 6/2 x 3 = 3x3 = 9

I had my 11 year old do it
he is much sharper than his old man...

Using BODMAS... he got 9

OK, I reckon I finished school much more recently than most guys here... but what the hell is BODMAS and PEDMAS and all that?

I just had maths... hoërgraad en standaardgraad... HG en SG...

Dis hoekom vandag se kinders nie meer wiskunde kan doen nie, daai BODMAS en PEDMAS goede is iets wat jy moet leer, wiskunde is logies

Daai is duidelik 'n vraag uit 'n "outcome based" vraestel...wag tot hulle technikon of varsity slaan met differensiasie & integrasie. Hulle sal vinnig leer on hakies te gebruik

Schooling these days is a crying shame.

I have to fork out big$$ every month for private schooling to teach my kids what I learned in an average run-of-the-mill government school!

God help the poor kids whose parents can"t afford to do that. a country is only as good as its education system.
I heard the minister of education on the radio this morning saying "why is it that SA does worse than any other African country with more resources?"

More corruption maybe???

Cleaner · Post by **Cleaner** » Mon Jul 09, 2012 3:50 pm

I too came to 1 as the answer, but WolframAplha have decided it must be 9.

Best answer to the above and variations of this frustration as per the following website -

Quoted from http://knowyourmeme.com/memes/48293- I’m a math professor, and my view is that although the standard convention, if applied precisely and rigorously, does give an unambiguous procedure to follow, nobody, and that includes professional mathematicians, would ever write a formula like this.This is mostly because, after about 3rd grade, none of us ever use the division symbol ever again.
