It is not the language. Those will give wrong result if the formula programmed is not the same as in the book or where ever. I check results/programs using MathCAD 15, MathCAD Prime or SMath Studio. (SMath Studio is a free of Russian origin and very good. Russians have always been good with maths.) I have never found one mathematical mistakes in any one of those programs. Do not ask the results of other programs or quite a few apps.
The big problem is when the math is written right but the formula has a mistake. This is the case in the new EN standard I am working with just now.

What I find interesting is that so many people give the wrong answers to dead easy problems. Even so called pro's. And the internet is full of this lately.
I do believe the average intelligence has increased, but it seems the intelligence gap has also increased over the last decades.
No wonder this forum hasn't sent a space rocket to Mars yet...we still debating if the answer is 9 or 1

That expression is totally ambiguous and was either put together by some one who wants to create controversy or cant do math.
Send it back, tell them to it do it again while giving them a clip on the lug hole.

This is totally ambiguous and was put together by some one who wants to create controversy.
x = 6 / 2( 1 + 2 )
x = 6/ 2 (3) one first works out what is within the brackets
x = 6/6 this is where the controversy comes in
x = 1
now work it out backwards where 1 is y
1 = 6/2( y + 2)
therefore 2(y + 2)= 6/ 1
therefore 2(y + 2) =6
therefore (y + 2) =6/2
therefore (y + 2) =3
therefore y=32
therefore y=1
if the original x = 9 then
9 = 6/2( y + 2)
therefore 6/9 = 2( y + 2)
therefore ,66666 = 2( y + 2)
therefore y + 2 = 2/.6666
therefore y + 2 = .3333333
therefore y = 2  .333333
therefore y = 1.666666 and this is not true
it is then clear that the x in x = 6 / 2( 1 + 2 ) is, and can only be 1
Wat ek kan onthou van my matriek wiskunde in 1975 is die antwoord 1
Dit kan GEEL ook wees!

Tested with Delphi/Pascal, C, PHP. All gets compiler errors when you enter it as 6/2(1+2). They want 6/2*(1+2) : And that is what it is. 3(3)=3X3=9.

Exactly.
There is no reason to argue about the intention. The equation is not ambiguous. Maths will give an output based on the input and the rules of mathematics. So as the equation stands the answer is 9.
Should the person who wrote the equation desire the output to be 1, he should change his input.

It is  you of all people will know a programming language has strict syntax laws. That syntax will force you to program it unambiguously.
The reason you have never found one mistake is because you have obeyed their laws.
BTW  you can and do get different answers from different compilers on the same machine, and between different machine types. Especially with floating point and Trigonometric functions.

Right, so this is how I see it. (I have even tested the integrity of both equations in a standard x/y axis graph)

I learn from the mistakes of people who took my advice.
Like traffic rules that needs to be followed (OK not in SA anymore) there are mathematical rules to be followed.
The mathematical rules are summerised by (what I was taught) the acronym BODMAS
So the correct answer will be:
6/2(1+2)
=6÷2*(1+2)
= 6÷2*(1+2)
=6÷2*3
= 3*3
= 9
