Why would you learn the order of operations when you're still learning basic addition and subtraction. I learned PEMDAS in 5th or 6th grade...when we started pre-algebra.

Private school, and I liked math enough to learn some of it outside of school.
 
Re: TRP: Changing Conferences Since 1999

What is the order of operations? Never heard of it before. And yes, I'm being serious.
 
Re: TRP: Changing Conferences Since 1999

I don't remember when I learned it, but it wasn't 1st and 2nd grade....and I'm pretty sure not 3rd. I'm thinking 4th or 5th. And Brent, lets not critique my supposed lack of math skills until we master differential equations, mmmmkay.

Not saying you are not smarter in math NOW. Just implying you learned it later than I did in life. ;)

And MNS: a crappy private school? :D

I was thinking the same thing.

In order of which to do first:
Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

I'm not being clear I guess. What is "the order of operations" and what does it do, how do you even know to use it, etc? You were not condescending in your answer to me - you were trying to explain it - and I'm trying not to be a ***** to you but I still have no clue what any of you are talking about. I feel like you're all assuming knowledge on my part that I don't have. I have no idea what the order of operations is and how it's supposed to be applied to an equations like that. I saw this:

5 + 5 + 5 - 5 + 5 + 5 - 5 + 5 x 0

So I did this:

5 plus 5 equals 10, plus 5 equals 15, minus 5 = 10, plus 5 equals 15, plus 5 equals 20, minus 5 equals 15, plus 5 equals 20, times 0 = 0.

Why is that not how you're supposed to read it?

Do the multiplication first:
1. Parentheses
2. Exponents
3. Multiplication
4. Division
5. Addition
6. Subtraction.

Since Multiplication comes before Addition and Subtraction in the order of operations, you have to do the multiplication operation first. So only the single 5 is multiplied by the 0.

Math isn't done from left to right like reading, you have to work through function in a certain order, and that order is determined by this order of operations we're talking about.

Now THIS is the type of answer I was looking for. I still don't get how you apply that order of operations to that equation (since some of you have parentheses in your version of problem solving and parentheses is first but you just told me to use multiplication first) but it's more clear than it was.

Specifically:

1. The problem has no parentheses, so that step is done.
2. The problem has no exponents, so that step is done.
3. Multiply 5 x 0 => 0.
4. The problem has no division, so that step is done.
5. Add 5 + 5 + 5 + 5 + 5 + 0 (from step 3) => 25.
6. Subtract 25 - 5 => 20, then 20 - 5 => 15.

Once you know those six steps, you can rearrange the problem to make it easier visually. In this case, we grouped the addition and subtraction together, and the multiplication got moved further off to one side.

5^(((5+5+5+5+5)/5)-5)=?
 
Re: TRP: Changing Conferences Since 1999

Indeed.

Integral(1/n^2) from 1 to infinity? (A personal favorite of mine since the answer is so bizarre. (Yes, I have favorite integrals. I'm a math nerd, sue me.)
 
Re: TRP: Changing Conferences Since 1999

Why are doing calculus? :p

Now that I have a degree I don't need to do calculus anymore!
