Also, you completely misinterpreted my definition of "÷", half because you didn't read the word "denominator" and half because when I wrote out my answer, I didn't put in the proper brackets to be completely clear - which is the whole problem.

When I say it separates out the left side into numerator and right side as denominator, I mean 48 is the numerator and 2(9+3) is the denominator or:

48
2(9+3)

Or to be completely clear:

48/(2*(9+3))

Clear? I'm not wrong because it is how I interpret the question based on what I was taught - in like grade 4!. (I think it was also commonly taught in Canada that when given such equations, you would often progress from left to right on even order of operations, such as division and multiplying.) Quit not understanding whether intentional or not.

actually i misunderstood nothing, go back and read. i said you are wrong because you cant treat it as a denominator if its not 1 term. with out the brackets you gave it its not 1 term and cant be the denominator

a = b

a2 = b2 = ab

a2 - b2 = a2 - ab

(a+b)(a-b) = a(a-b)

Now, divide both members by (a-b).

a+b = a

a+a = a

2a = a

2 = 1

a and b are 0

he wrote it wrong, guess you deleted your post kael

Or you're deluding yourself to make yourself look smarter. I didn't post anything.

I beg your pardon?

a^2-ab = a(a-b), because the term in common is a. You can't multiply a for its exponential, 2.

What - have you not taken factoring? Replace 2 with X

48÷x(9+3)

It's one term because it's connected to the bracket which MUST be dealt with first. The question you are after is do you drop the brackets once you add. I would say no, again, based on what I was taught.

2(9+3) or 2(12) is still one term and can be treated as such.

In any case, I'm convinced you're just trolling now.

With his recent string of posts...I'm not convinced.

i wasnt thinking it was an exponent the way it was written. you know exponents arent the size of a normal number

ACt · 04-08-2011, 12:38 PM

Aww fuck... new answer:

48÷2(9+3)
= 48÷18 + 6
= 2 2/3 + 6
= 8 2/3

This is why Mathematicians hate people

And you know that these forums don't have an intuitive way to put the 2 in the right place, so kluang just made the notation a2.

Also, if it was a*2, the notation is 2a, not a2.

Fixed and I see what you did there, distribution of the terms, also valid without the adequate brackets.

Edit: see? In the reply box a2 was perfect, and when I posted, it became a2. So yeah, it's a^2.

so you agree with the juxtaposition, but you simply said that you would set it as the demoninator becuase of the division sign, thats a completely different scenario.

Everything after it is in the denominator.

thats wrong, only if its 1 term

ACt · 04-08-2011, 12:43 PM

AF - I forget if you ever said, what do you do for a living?

EDIT: @ Num - no, I think it is just people in general.

EDIT2: AF again - I was talking specifics - this case the equation you provided. The equation you've given is linked by division, multiplication and brackets. I put the division sign as the way to orient the whole equation properly. I was not saying "IN ALL MATHEMATICS..." because I'm not stupid. You are just looking for errors so make yourself the big man - go away, your trolling is not wanted.

Besides, has it ever occured to you, or anyone, that the set up to this whole thing is "500 of 1000" got this wrong when there are two answers? Yeah, so believable. I call for thread closure.
