What is the answer to this?

This isn't even an interesting example of Order of Operator mistakes. The other one was more interesting.

 

[Leoreth]

That was the normal division symbol when I was at school.

Elementary school perhaps?

Division is a lot less confusing when written as fractions.

 

[GoodGame]

The order is brackets (inner-most first), exponents, multiplication and division (left to right), and then addition and subtraction (left to right).

There's no bracket or exponents so one should evaluate the multiplication and division first.
After doing that the equation reduces to:

6 - 0 + 1 which equals 7.

All the way into high school. I am most probably a decade older than you.

 

[Borachio]

Are you telling us they didn't teach you this in grade school ?

I beg your pardon?!

Using Polish_notation of course, this sort of difficulty and ambiguity doesn't arise.

So that / + x - 6 1 0 2 2 = 7.

If that's what the question is asking.

6 - 0 + 1 needs to have the addition done first, so it's 6 - (0+1) which is 6 - 1 which is 5.

 

[Borachio]

Help. See, now, why you can't do it without explicit bracketing or Polish notation?

 

[Leoreth]

6 - 0 + 1 needs to have the addition done first, so it's 6 - (0+1) which is 6 - 1 which is 5.

No, common mathematical notation has implicit left bracketing, i.e. 6-0+1 is equivalent to ((6-0)+1).

The other example was less a case of order of operations mistakes and more of deliberate ambiguity.

 

[History_Buff]

Aren't these sorts of questions usually meant to have some of conflict in the order of operations? This one quite clearly doesn't.

Indeed. As far as stupid questions go, this one is particularly dumb.

And as others have said, that division sign is an abomination. Use fractional representation, as it tells you how the order of operations is supposed to proceed.

Edit: Also, we always learned it as BEDMAS, for brackets, exponents, etc. You folks call them indices across the pond?

 

[NickyJ]

Impossible to answer without any indication of the priority of the operators. Sorry.

Multiplication and division always take priority.

Let's take the problem again:

6-1x0+2/2

Multiplication first, since it's on the left, gives us:

6-0+2/2

Division now, which changes it to:

6-0+1

Six minus zero is six, plus one is seven.

Unfortunately, I clicked the wrong answer in the poll.

 

[ZeletDude]

Seven.

BIDMAS rules that Addition comes before Subtraction.

No, addition and subtraction have equal precedence. 6-4+2 is the same as 6+2-4. Indeed, "6-4" is the same as "6+(-4)", i.e. "six plus negative-four".

The other example was less a case of order of operations mistakes and more of deliberate ambiguity.

Yeah, that's true.

 

[Borachio]

Multiplication and division always take priority.

Only if you define them to.

 

[Truronian]

It's seven.

If we're doing easy maths sums, I've got another one:

Spoiler :

3+4-2=...

[Antilogic]

I got 7, although I double-checked myself a couple times because I thought there was going to be a trick.

I beg your pardon?!

Jesus tapdancing Christ, no wonder they got partitioned.

It doesn't mean you eliminate numbers. Zero was invented as a placeholder for nothing, seems kind of weird to not use it to hold the place of nothing.
