Not on the AYE.

 

Anyway it's a poorly 'worded' maths question that invites two answers.

 

its not...

its very clear to me...

In my maths day....if the '/' is written 'short' then the (1+2) belongs to the numerator.

If the '/' is drawn long to cover the (1+2) then obviously it belongs to the denominator.

 

The problem is now we use computer to write out the formula, and it cause confusion where the brackets belong.

in match question.. if writen on paper we wont be using / to represent divide lah.

6/2(1+2)= 6 / 2 x (1+2) = 6 / 2 x 3 = 3 x 3 = 9

the answer ... is and always will be ...

It depends on how long is the divisional line.... If the teacher drew a line beneath the 6 long enough to cover the () then answer is 1, if the teacher stop short of it and the () is left independent then the answer is 9.

 

If the question was printed and it's typed as 6/2(1+2), it should be read as 6/2 * (1+2). To set it otherwise it should be 6/[2(1+2)].

 

So what is typed or written?

 

 

 

Anyway the mathematics order applies....

Simple it's 9.

 

Rule 1. Calc all workings enclosed in brackets first

 

(1+2)

 

Rule 2. Remove the brackets.

 

Rule 3. Calc the first multiple or division symbol first

 

So its 6/2(1+2)

 

becomes 6/2(3)

 

Becomes 6 / 2 x 3

 

Apply rule 3 = 6/2 = 3. 3 x 3 = 9

bro the original question dun hv /.. only the division symbol.... so it is actually very clear..

 

This is the question:

The order of operations, or precedence, used throughout mathematics, science, technology and many computer programming languages is expressed here:

 

terms inside parentheses or brackets

exponents and roots

multiplication and division

addition and subtraction

You are talking to someone who churn out CHAID analysis like someone working on 1 + 1.

 

Didn't my explanation explain your point? I didn't bother to go google or wiki thats all.

Try to key into exel =6/2(1+2)

 

does it come out as 1?

[SimonTan]

Excel answer is 9.

So yes we conclude the answer is 9.

The richestest man on earth has approved 9 as the answer.

So he must be right,

abit strange to even have this type of discussion right?

 

its either right or wrong,

dun have ambiguity one ma....

 

 

 

but i saw this b4 on another website

simple and good answer.

my answer still 9 lo.

that is what I am saying.

 

Anyway I think that cal with 1 is those type where old answer will still remain while U key in equation until U press =button.
