142 is not wrong! Assume it was in base 9 and you get 142 so it's right.

Obviously it's wrong. Because you have to assume the norms. Just because someone says otherwise due to some weird perspective, that's a difference of opinion.
Which is up to each of us whether we respect or not, but if you tell me I'm factualy wrong because your opinion is different I will consider you a jerk and may ignore you, shoot you, and that.

127 is correct.

Anyone found a diesel-engined aircraft yet?
 
You don’t need brackets.
OK...

So why did you put them in?

If numbers are in brackets, those sums are done first.
But in the question the brackets (which according to you are not needed) are not there.

Try entering the original calculation without the brackets which werent needed in the first place:

14x7+11+6x3=

and tell us what you get.


Your way is plain wrong.
What you are saying there is that countless billions of calculating devices are wrong because they dont follow one particular rule which you think should be the only rule.

What you are saying there is that at least one programming language is wrong because it doesnt follow one particular rule which you think should be the only rule.
 
OK...

So why did you put them in?
The brackets? I didn’t. I just typed them in the address bar, pressed enter and let Google do it for me. Try it yourself and see what you get. I’d assume that’s because how it is done when you don’t put your own brackets in. Ask Google why they put them in…..

It's 127 without the brackets because the order of calculation is set down in the convention of mathematics.
How would you know? Ask any maths teacher. It's like grammar and spelling in English. There's a correct way and others are incorrect.

You can use a different base number instead of the 10 which is our convention - it works if you stick to it but it's wrong in the accepted convention.
You could apply a reverse-polish method to the numbers and get a different result, or run the numbers some other unconventional way and of course get another, wrong, answer.

You need conventions otherwise you can't do what we call mathematics.
BIDMAS is it.
