With no symbols to help, I’d default to multiplying items together
So if I gave you a shoe and said "That is worth 5"
Then I gave you another shoe and said "Now how much do you have?"
Your answer would be 25??

That is using commoners sense.
The man with shoes and cones is not a man plus the shoe and cone symbols, it's an entirely new symbol that is distinct from the others. It is not explicitly explained what this new term is a function of.
If we are going to use a physical/material construct to argue the value of the man, shoes and cone -how do you know the value of the shoes and cones are independent values, and not dependent - eg is the value dependent on whether they have been worn and half eaten by said man?
Indeed. And 50% of them are 33% beagle.
so those voting square roots... is that + or - or both?
Your answer would be 25??
Well yes. This is a maths problem, so if you said the left shoe is x and x = 5 and the right shoe is y and y = 5 and then you said (with no maths symbols) what is the value of xy, I would say 25...

We haven't even got that far yet... 😉
if you said the left shoe is x..
But we didn't. We said 2x = 10
You are confusing algebra and simple counting.
It becomes algebra as soon as symbols are used to represent something. The problem states that shoeshoe = 10 so xx = 10, if Shoe Shoe meant 2x, it would be 2shoe or shoe+shoe.
If it was a counting problem, it would be structured along the lines of "If a shoe is worth 10 and Stacy had two shoes, the monetary value of her shoes would be £20".
I’m starting to get the distinct impression that those that come up with these puzzles are similar to people who can speak Klingon or Elvish. They’re the only ones that think they are cool or clever. Everybody else thinks they’re a massive prick.
In this case, the person who came up with this can speak neither Klingon, Elvish or Math....
No idea about my Casio fx451. Is that cheap? or scientific?
It's a scientific calculator, and it definitely does BODMAS. I have the same one.

Funnily enough with this and the last one I come to a similar conclusion, my main comparison being the eejits who love cryptic crossword puzzles. (That's me by the way. 🙁 )
We said 2x = 10
You did. I only used x and y as it was more concise than saying 'left shoe' and 'right shoe'.
So 'left shoe''right shoe' when you are not told how to evaluate them, would mathematically become the product of the two, as in xy...
At least one of us is correct GrahamS, what is the chance we are both correct?
Life must be very confusing for those who see simple counting as algebra:
"Hello shopkeeper, I'd like to buy these oranges please"
"Certainly, five oranges is 50p"
"Actually, make it six."
"Okay. Each orange is the fifth root of 50p, so six oranges are £1.09"
"Whaaaa..?"
😆😆
The problem with this sort of puzzle is that it can be interpreted in multiple ways (often deliberately so, I suspect). Positing that left shoe = 1 and right shoe = 9 would be equally valid (though I don't think it makes a difference to the outcome in this case).
However, let's not forget, it's a Facebook meme. The target audience isn't Maths PhD's, it's people who can't spell 'algebra' or count without moving their lips. Occam's Razor applies here.
It's arguably not even a maths puzzle. Anyone who vaguely remembers high school maths should be able to work it out in a heartbeat. It's an observation puzzle.
