The reason people complain about never using the math they learned in high-school, is because math isn’t about equations and symbol manipulation. Sure, that’s a part and it’s the part instructors tend to focus on. Math is really about general truths which help you understand relationships between ideas. Once you have a deep intuition about how a branch of math works, you can use it on any problem which has those same relationships.
Knowing 3×5=15 isn’t exclusive to counting three bags of five oranges. It applies to bank accounts, buildings, people and profits. The same is true for calculus, statistics and other advanced maths. If you get the intuition of how the relationships in math work, then you can use it on any problem, even if it is something you’ve never had any experience dealing with before.
That’s the real power of learning theory. Not that it replaces learning through experience, but that they make it far more powerful. It cuts down trial and error, helps you see patterns and think of new solutions to problems. Because often the best way to change the world is to first understand how it works.

I just can't believe that this is worthy of a thread...
It's just a simple case of learning the rules of in which order to apply addition, substraction, multiplication, division, powers, other operators and brackets.
Google/Wiki it, learn it by heart, no more problem.

And to those who want to make this a more philosophical issue: Don't!
No need to change the rules, only need to teach them consistently, drilling them in so people won't forget and voila, people won't have any problem with these fake problems.

Depends.

Sometimes the Operands dictate that the addition sign is done prior to the subtraction.

As such:
10 - (1+1+1+1+1+(1x0) = 5
or
10 - (6x0) = 10.

With the communative property, we also are allowed to derive:
10 - 1 = 9. (as 5+1 = 1+5)
or
10 - 0(6) = 10

No. It never depends. Order of operations is perfectly clear and rigid.

There are no brackets, ergo no Pemdas or Bemdas, or any other version that represents the Bracketed experience. That leaves us with multiplication, addition and subtraction.

Subtraction in this case has to be done independent from the rest because it does not possess commutative or associative properties.

It might be possible to produce a distributive property if you can provide a quadratic system that will provide a very specific qualifier such that the last value within the last variable can be quantitatively stated as being A x B. (while also removing any exponential components from the last representation of the number 1 from our string of numbers.)

How do you mean, 'update'?
Any other variation would just be a new notation or new rules of order -- exactly the same issue.
if people don't bother to recall rules now, how are new rules going to help?

(There is no possibility of just removing the rules; it is absolutely necessary to have a set of rules that specifies order.)

Average people use math all the freakin' time, it's just not usually in long form like that.
They do it so often they don't even have to think about it much.

Laws trumps rules. Follow the property listings.
Pemdas,Bedmas, or any other kind of consonent/vowel subjugate of 2 values that is simply a implication known for being an order of predicates is more and less derived from the property system of numbers.

If the system doesn't provide the correct relationship, it isn't a correct answer, nor properly annotated via the lovely jibberish we humans like to cough up. (whatever that is.)

The reason why I say it's a kind of quadratic is simply because how awesome 1 exponentials are. They always equal one ergo it's simply a simplification of the multiples of values that give provides a multiplication by 0 which makes this question so very awesome. For some reason, only 1 version of a multiple of 0 cannot be reduced to the actual number 0, in this case. All others are normal multiplication values that give you a +(a,b) relationship where one value == 0.
