a2. [latex]6/2*3[/latex] ; did nothing but removed the parenthesis
I can see this getting to 20 pages as well.I agree with you 2.
Juxtaposition (multiplication without the sign) takes precedence over the division.
Therefore 1 is the result.
However this question has returned over 20 pages of replies in the other forum, some saying 1, most saying 9.
That's why I thought I'd ask a 'smart' forum instead lol.
I have another card up my sleave: Wolfram|Alpha: Computational Knowledge Engine which is the inventer of Mathmatica
Here is his say: 6/2(1+2) - Wolfram|Alpha
I take it my previous reply helped to clear things up a bit?
So there is no consensus on any forum re the relative precedences of implicit/explicit multiplication...Hi guys,
On another forum of which I am a member, we are having a discussion about the above equation.
Some people read the equation as:
(6÷2)(1+2) in which case the answer is 9.
Some read the equation as:
6÷(2(1+2)) in which case the answer is 1.
Google and Microsoft (and other computer) calculators show the answer as 9 whereas good scientific calculators show the answer as 1.
Anyway i thought what better place to ask than here.
So go ahead guys, is the answer 1 or 9 and why?
The second is not quadratic (nor are the others).1.....those are 2 different equations, watch you notation, equation 1 & 3 are the same(equal) the brackets are not needed in #3 since equation follows order of operations, the second equation is a quadratic, way different.....the brackets hold it "apart", if someone is mixing the 2 it is wayyy wrong.....
to answer the question, just work it out using BEDMAS,
The link you provided [in a subsequent post] even states that neither approach (i.e. implicit/explicit multiplication equivalence OR implicit multiplication precedence) is universally accepted. Is it not possible that the equation is potentially ambiguous?
I'm sorry, I got the impression you had an agenda (that you wanted people to agree with your views/beliefs):More than anything, I wanted to see which way was more accepted on here. Also, (I think) it makes interesting conversation.
But that's where you went wrong...Juxtaposition (in this case, multiplying using brackets instead of the x sign), takes precedence over multiplication and division.
I think you've added some extra brackets up there... You have done a substitution based on the assumption that the implicit has the higher precedence.Do distributive rules comes into it at all?
For example:
A(B+C) = AB + AC
Therefore
6÷2(1+2) = 6÷((2*1)+(2*2))
I think the problem comes from what people read A as. Some people read it as A = 6 and some people erroneously (in my opinion) read it as A = 6/2.
I think that if it should be read as A = 6/2, then 6/2 should have brackets.
