Thanks for this answer.

Actually in the case of x / 1 * x I would go for x^2.

The issue I have is that 2(1+2) implies you expand out the contents of the bracket first.

Now IF It said 6 / 2 * (1+2) then I would answer 9.

2(1+2) is NOT equal to 2 * (1+2).

Er..

9. It's 9. It can't be 1.

6/2 is a separate fraction, and is not part of the second term in any way and vice versa. You multiply the fraction by the product:

6/2(3)

Which can only equal 9. The brackets merely ensure that the 3 does not become part of the fraction's denominator.
 
Ok for those that think their calculators are giving them 1. Plug in 6/2 * (1+2) (don't forget the multiplication sign) in and report the answer back.
 
ah well that makes sense , seems we have a classic case of wrong calculator mode, been there done that , failed the exam

How come people don't like the division symbol, how is it any different from a '/' slash? Eh?

Because anyone with half a brain would note the problem down as it is in my two wolfram alpha links, eliminating any confusion from proceedings.
 
The slash symbol isn't great either, it's just difficult to write fractions on a computer. Ideally all divisions should be displayed as fractions as then there is no abiguity as in the OP.

That would be 9.

It's not 6/2*(1+2)

It's 6/2(1+2).

They're not the same.

Bodmas interprets 6/2(1+2) AS 6/2*(1+2)

I immediately thought:

6/2(1+2)

6/2(3)

6/6

1

But then Zefan mentioned BODMAS, which means i'm wrong, it's actually:

6/2(1+2)

Brackets: 6/2(3)

There are no operands.

Division next: 3(3)

Then Multiplication, gives an answer of 9.
