6 - 1 x 0 + 2 ÷ 2 = ? (1 Viewer)

[Dan Lambskin]

In reality you usually have some context about why you're performing the maths...I can't think of an on the job application where I've just been provided a random string of numbers and operations

 

[timschochet]

OK- so why do we have an order of operations rule? I get that we have one but what's the logic of it? Wouldn't it be far simpler to go from left to right unless there were parenthesis?

Aside from destroying the commutative property and all proofs that depend on it, sure.

it wouldn't destroy anything for real would it? Certain equations would have to be redone, but the results would be the same in the end.

Exactly.

And since I'm not a math homo...if someone hands me something like "6-1x0+2/2 = ?" I'm going to "read" it as "six minus one...times zero...plus two...divided by 2". If you want parenthesis and brackets and #### put them in there.

These threads really let you know who hit their math ceiling in 3rd grade and who did not.

This is grade school math, it should be common knowledge. Are you arbitrarily deciding that it's dumb just because you didn't remember it?

It's there to avoid confusion, as otherwise the answer could be different depending on how you read it. You could also use parenthesis every time, but with a clear and easy to remember set of rules it isn't really necessary.

I never said I didn't remember it. I came up with the right answer, BTW.

Not everybody "learns" or looks at math the same way. It's easy to take that for granted.

Agreed. That's why they make those rules, so that everyone looks at it the same way.

I see what you're saying now, though. Not that you didn't remember the rule, but that you wouldn't think of it in real life if someone handed you some math.

I think it's because it's more natural when you throw variables in there.

consider 6-x+y/2, and evaluate this expression for x=0 and y=2.

Until you get to more advanced match (like, say, 6th grade algebra) at which point it's much simpler to have an order of operations.

6x² + 12x + 36 ≠ ((6x)² + 12)x + 36

Yes, but his subject is much cooler than mine. That said, I'm working hard to take mathematics away from the dark side (Algebra leading towards Calculus) to the light side (Statistics). Its not been an easy journey.

Why does A come before J ? If you say the "J" you say it like "Jay" and the A sound comes after the J letter there. I just find things like this interesting and like discussing it and if people don't like it they are free to not respond.

Until you get to more advanced match (like, say, 6th grade algebra) at which point it's much simpler to have an order of operations.

6x² + 12x + 36 ≠ ((6x)² + 12)x + 36

I accept that exponents and integers multiplied by variables would be done first, but beyond that why can't parentheses be used?

6x2 isn't the same as (6x)2

You get 6*12 versus (6*1)2

So 6 versus 36.

6(1/6)^2+12(1/6)+36=((6(1/6))^2+12)(1/6)+36

6(1/36)+2+36= (1+12)(1/6)+36

1/6+38=13/6+36

38 1/6 = 38 1/6

6x² + 12x + 36 = ((6x)² + 12)x + 36

6x² + 12x + 36 = (36x² + 12)x + 36

6x² + 12x + 36 = 36x^3 + 12x + 36

6x² = 36x^3

1 = 6x

1/6 = x

 

[Mr. Ected]

My 6th grader looked at it for a minute and nailed it. When I showed him the PEMDAS chart, he changed Parenthesis to groups for Parenthesis, Brackets, Absolute Value, etc.

He then said "That was easy! Was just doing that at school."
