Poll: Another Math Question

[Saelune]

Wow, alot of people forget you multiply before you divide. Its 1 people.

6/2(3), you multiply the 2 and 3, THEN 6/6 is 1.

Multiplication and division are interchangeable, just as addition and subtraction are interchangeable.

You wouldn't say 5 - 4 + 1 is zero, would you?

Yes. Yes I would say that is 0. I was taught something and actually remembered it. And I thnk more people were taught PEMDAS than interchangabillity. And if say, this was on a test, I would likely win an argument that Im just using what I was taught.

 

[AgentBJ09]

It's 1.

By Order of Operations, it would be...

6/2(1+2)=? / (1+2) first, then 2(3), and finally 6/6 to get 1.

 

[Wuffykins]

And for those who still are like whaa?
Look at it like..
6/1 * 1/2 * 3/1

For the record, those of us who are saying 'Whaa?' are probably seeing the equation like this:

Oddly enough that's how the calculator on my comp is choosing to interpret it as well. As mentioned before, the equation should be a written a little more specifically.

 

[aprildog18]

Oh my...
First, plug it into a calculator and see what you get.
If still confused because (1+2) is on right side of "/", it does not mean 5/20+3 is 5/23. Division symbol does not denote an open and closed parenthesis.

5 - 4 + 1=2 (berp de derp) Think of it as all adding, so it would be 5 + (-4)+1. negative 4 plus 1 plus 5 is...not 0.

The people who were smart enough to invent math were not stupid enough to put loopholes.

Your calculator is high then.

If the people who taught you math would let you get away with that you should go throw batteries at their heads. Because that is uncool of them, the question in this thread is uncertain because of the clarity that standard keyboard versions of math notion are lacking. 5 - 4 + 1 = 2, forever and always.

Holy shit, is this guy for real?

You were taught PEMDAS wrong. Very, very wrong. It's nice to see that you lashing out against me for this, but the reality is that addition and subtraction are interchangeable and read left to right, and multiplication and division are the same.

You can argue with me on this, but you're still wrong. 5 - 4 + 1 really means 5 + (-1) * 4 + 1, and 6 / 2 * 3 really means 6 * 2 ^ (-1) * 3.

This is fact. You're not going to change this by "winning an argument". Drink it in, kiddo.

Thinking about it, I guess it would, since if I put it into a calculator, I would likely have done it in order. But in anything with more stuff, Id follow PEMDAS, and I dont think I should be put down for using what I was TAUGHT.

@Saelune
TiefBlau is still right though, and well....at least you learned now than later (hoping that you did learn from him).
Now...If I told you all dogs spontaneously combust, and you tell everyone in the world that, they are still going to laugh at you even if someone else told you it.

 

[Smooth Operator]

Yet again a faulty equation does not a mystery make, it simply makes it faulty.

 

[Jewrean]

It's 9 I believe, also fuck math.

Fuck college algebra too. Worthless information as far as my major was concerned, such a waste of my time. Yeah, i'm bitter about it 2 years later.

Then why did you choose the subject for the degree? Or are you talking about High School and therefore still just whinging like every other high-schooler?

That's why I said to throw batteries at their heads, not your own. PEMDAS (or BEDMAS as I was taught, its the same shit), is supposed to include interchangeability. If they didn't teach it that way they taught it wrong, its a fundamental part of that idea.

I have a better Mathematics question:

If the volume of Earth is 1,083,210,000,000 km cubed and the Mass of Earth is 5.9742 × 10 to the power of 24 kilograms then what is the average mass of one cubed meter of Earth? And no I'm not converting anything into the archaic imperial system for you.

Show your working.

 

[archaicmalevolence]

nine

 

[Mythril225]

the correct answer is 9,
and google agrees with me [link]http://www.google.ro/search?aq=f&sourceid=chrome&ie=UTF-8&q=6%2F2(1%2B2)[/link]

 

[thirion1850]

PEDMAS, BEDMAS... blah blah, 9.

Well, sure you can't be blamed for doing what you were taught, but that doesn't mean you should parade around the fact that you're wrong as if the teacher's words invalidate hard fact. This isn't a court trial. I don't care about supporting my team, playing by the rules, or "winning" anything. I care about being right, whether or not I have to correct myself. Maybe that's a little beyond you.

I put [(5.9742 × 10^24 kg) / 1,083,210,000,000 km cubed] into Google. The answer is 5 515.27405 kg / m^3. That's 46.0271926 pounds per US gallon, which seems reasonable (within an order of magnitude) since water is about 8 lb/gallon.

Also, when I did the first calculation, Google returned this page as the first result (under the calculator thing) as soon as I'd entered [1,083,210,000,000 km cubed], and this page was the only result (other than the answer) for the full query. Amazing.

EDIT: I should mention that I actually do know how to do the conversion myself (yes, km^3 -> m^3 is easy to get wrong), I'm just lazy and/or I think I'm clever.

Also, I just noticed that your × isn't a normal x, good job.

Dont presume to know me whiel you sit on your high horse of snobbery. If you want to prove you are right, then prove you are right. So far you have just belittled me with personal attacks.
