Re: Math: 6÷2(1+2) = ?
Oh Boy, I'm representing our South African Education system here during apartheid years.

first thing i remember: "÷" is not the same as "/" dont ask me why, I cant bluddy remember, but whenever you see "÷" you must put the unknown in parentheses which changes the direction form left to right TO right to left.

"When dividing an [unknown] or [x] with "÷" put unknown in parenthesis and calculate first, then remove parenthesis"
"When dividing an [unknown] or [x] with "/" all follow the same rank, left to right.

thus

6 ÷ 2(1+2) is not the same as 6/2(1+2)

Using waht the OP gave us we have to use our parentheses on unknown and it looks like this:

is 6 divided by [2(1+2)]

6 divided by [2(3)]

6 divided by [6] now remove parenthesis

6/6
= 1

6/2(1+2) on the other hand is 9

Re: Math: 6÷2(1+2) = ?
multiplication does not occur before division

they are the inverse of each other

you work left to right and perform either according to what comes first

1 or 9, depending on your country. In Russia it is 9. Because in Russia dividing and multiplaying are of the same level and being solved left to right. Fortunately we do not have a confusing PEMDAS...
Quoting: Anonymous Coward 1306057

This. We didn't have PEMDAS either in the USA when I went to school.

In a respectable setting, it would be clarified with parens whether one does the multiplication before the division (since there's a bias toward that), or works left to right and therefore the reverse in this case.

Yeah, thats it thanks, "÷" is not the same as "/"

The symbol "/" is called a solidus (sometimes, the "diagonal"), and the symbol "÷" is called the obelus.

Re: Math: 6÷2(1+2) = ?
ive added more than enough explanation

go type it into a calculator or even excel and you will get 9 !

its simple

the calculation expressed in a linear formula is a totally different equation to the one you then decided to express as a fraction

if you want it to equal 1 you need to add the extra brackets like i showed you before

Taking the ratio x/y of two numbers x and y , also written x÷y. Here, x is called the dividend, y is called the divisor, and x/y is called a quotient. The symbol "/" is called a solidus (sometimes, the "diagonal"), and the symbol "÷" is called the obelus. If left unevaluated, x/y is called a fraction, with x known as the numerator and y known as the denominator.

Therefore, the way I presented the equation is valid because the obelus (÷) remains unevaluated ( 6÷2(1+2) ) and in turn can be understood as a solidus, which denotes it as a fraction.

Yes, if you don't account for the (1+2), but IN THIS CASE BECAUSE IT IS JUXTAPOSED to the 2 and there is no multiplication sign that exists between the two, it's implied that the whole 2(1+2) is part of the denominator.

no that is not implied - you are wrong

what is implied is the multiplication between the 2 and the brackets

you dont need to show multiplication signs when there are brackets like that - it is a given

Here comes the recycled arguments.

The way I presented this equation, in a linear sense... does not exclude it from representing:

6
___ = 1

2(1+2)

If you can't understand that, no amount of arguing will ever change your mind.

Thank you! But brackets not needed...I will explain.

People, seriously I just finished pre-calculus (Math 111) and PARENTHESES FIRST

P lease
E xcuse
M y
D ear
A unt
S ally

Parentheses
Exponent
Multiplication
Division
Subtraction

Parentheses (1+2) ok...so now I add them up...(3)

6 / 2(3) (sorry I'm using a laptop all I have is the slash key for division)

NOW ---> Multiplication BEFORE Division ( P E M D A S )..so.. 6 / 6

NOW we divide....( P E M D A S )

1

I am seriously AMAZED at how many different answered have been conjured up on this thread.

Given they are all CORRECT in their path. No miscalculation or anything. Of course whoever said 0 is a total loss..LOL sorry but there is no way 6/6 = 0...

But I'm sorry guys...just because you did not miscalculate does not mean you did it right. There are RULES in math, as within every science (otherwise WTF is science? Politics? NO) and you must follow them.

This thread is almost like Dem vs. Rep vs. Lib

Except in math you must follow math.

2(1+2) is not the implied denominator it IS the denomonator, its stated as the denominator quite clearly.
Thats why the answer is one. If you've come up with an answer that is not 1 you are stupid, mentally deficient, and should do humanity a favor and comit suicide before you breed. If you've already made some little talking monkeys kill them first then yourself.
