Can anyone help with this?

No brackets in the question so surely BODMAS doesnt come into it.

With brackets answer 20
Without then the question becomes 5+3×8 which is 40

No disrespect but.... you (or some people) are arguing if it's 20 or 40?😂 Then not many can give the correct answer for this I assume😂😂😂 (was sent this by a colleague last week which had been on social media for some time obviously):

10+ 10 + 10 = 30
5 + 5 + 10 = 20
4 + 4 + 5 = 13
5 + (15 x 4) = 65

I think that's right...

Boy + shoes + double whatever that is in the newspaper. Although technically I'd argue that it's unanswerable, as we can only calculate the value of the pair of shoes. The value of each individual shoe is undefined.

I think it's 14 chips ............

Three pairs of shoes = 30, so pair of shoes = 10.

Two person + 10 = 20, so two person = 10, so person = 5.

Two pair of cones + 5 = 13, so two pair of cones = 8, so pair of cones = 4.

If each shoe has the same value, shoe = 5.  If each cone has the same value and a cone at an angle is the same value as an upright, cone = 2.  So:
shoe + (person + pair of shoes + pair of cones) x cone = 5 + (5 + 10 + 4)  x 2
= 5 + 19 x 2
= 43.

However:
there's nothing to say the left and right shoes have the same value;
nothing to say a cone at an angle is the same value as upright cone;
nothing to say whether a person holding a pair of cones and wearing shoes is additive or multiplicative;
the person has a pair of shoes on but we can't see if they still have their socks on so don't know if they've lost the socks and therefore aren't worth 5 anymore.

6 x bags = That is the convention. The reason is that without the convention there is considerable ambiguity as to what the question is asking, with the convention it is absolutely clear - at least to anyone who follows the rules. With careful use of Bodmas and brackets, it is possible to write that expression so that it's meaning is absolutely precise. Without this convention, you have to guess what is required. Guessing is not mathematics.

5 + 3 x 5 = 20.  

You do the multiplying first.  So, you do 3 x 5 first (15).  Then you do the addition.  5 + 15.  20.  

Why?

Because that's the rules of maths.  It's known as BODMAS which stands for
Brackets
Order
Divide
Multiply
Add
Subtract.

So (5 + 3) x 5 = 8 x 5 = 40.
5 + (3 x 5) = 5 + 15 = 20.
Both of these are clear because you do what's in the brackets first.

5 + 3 x 5 = 20 because, without the brackets, you do multiply before add.

Order is another way of saying 'to the power of', like 2 cubed, i.e. 2 to the power of 3 or 2 to third order.

Thanks AA, I genuinely didn't know.
I was being facetious with my comment.
I'm old and simple minded and work on the principle that anybody who messes with 2+2=5 must be a cnut. 

30?

That question I can answer without any fear of getting it wrong.

BODMAS always comes into play.

I'm absolutely surprised there's even debate on BODMAS... This would never be a question in China. You have different maths rules in England?😂😂😂

No, just people without a proper mathematical education.

(Not, as some people might think, 40). 

Why not write it as 5 × 3 + 5, and not make a meal of it?

It was a restaurant, always likely to be a meal involved...

Never heard of it when I did my Pure Maths A level.

Bodmas is misleading anyway: dividing doesn’t precede multiplying and adding doesn’t precede subtraction. When the rule doesn’t apply, you go from left to right.

I got 17.5
