6÷2(1+2)=?

reply to post by IamBoon


Simply doesn't matter.

A = 6/2, B = 1, C =2

A (B + C) = AB + BC

6 / 2 (1 + 2) = 9

(1 + 2) is NOT a denominator PERIOD. If it were it would be 6 / (2 (1 + 2)) but it is NOT.

Yes and if you want it to be 1/3, then you should write (1/3). Otherwise A is taken to mean the number directly before the brackets.

Wrong!!!!

1 / A (B + C) = (1/A)B + (1/A)C, NOT AB + AC.

Using your logic I could say that 6/2 is NOT a fraction PERIOD. If it were it would be written as (6/2)(1+2). And I agree.

No kidding, but I didn't write that did I?

1/3(B + C) = B/3 + C/3 or 1/3B + 1/3C

A ( B + C) = AB + BC

"A" can be any damn thing you want it to be!!!

You people pass algebra???

Sorry mate, it was my problem with my eyes..
In your case, 6÷2x(1+2) or 6(1+2)÷2 or (6÷2)*(1+2)

but the question in this problem is different, it is 6÷2(1+2) where numerator is 6 and denominator is 2(1+2)

Guys, what is 15y ÷ 5y ?
Did you get 3 or 3y^2 ?

If your answer was 9 in previous question, you should get 3y^2 because
15y (÷) 5y
= 15 (x) y (÷) 5 (x) y
= 15y (÷) 5 (x) y
= 3y (x) y
= 3y^2

*(x) = multiply, (÷) = divide

15y ÷ 5y = 15 x y ÷ 5 x y
= 15y ÷ 5 x y
= 3y x y
= 3y^2

What if you got answer 1 for previous question?
15y ÷ 5y = 15y/5y
= 3

So, back to the question 6÷2(1+2)=?

Let x = (1+2) = 3 -------------eq 1

6÷2x = 3/x

Put eq 1 into 3/x, you get
3/3 = 1

That is the best way of explaining it yet.

15 x y ÷ 5 x y != 15 y ÷ 5 x y

and

15y ÷ 5y = 3

15y
------ = 3
5y

15y is 3 times bigger than 5y!!

15y ÷ 5y

The way you have it written it seems obvious that you want it interpreted as:

15*y
------
5*y

However if you follow the rules of a linear equation such as the one you have written, technically you would need parentheses to denote what is in the denominator.

15 x y ÷5 x y Interpreted linearly is technically

15*y
-------- * y
5

which would be 3yy or 3(y^2)

It is obvious what you are attempting to write, but technically parentheses are required to put the 5y in the denominator.

Exactly! Much the same as

6÷2(1+2) != 6÷2*(1+2).

Complete and utter nonsense. Tell me what level of math are you educated to?

Sorry you are using x as the * instead as x as a variable. see notation is the problem. on a computer the symbols are /, *, +, -

an x is frequently a variable. I haven't used an "x" as a multiplication symbol since elementary school.

a dot, parenthesis next to numbers or variables and *, which is the computer form of a multiplication dot, are all multiplication.

LOL it's really none of your business

This is a discussion, not a # measuring contest.

Answer would be 3y and that is not a solvable equation. Only one taht can be simplified.

Ok ill bite.

The way you have it written it is obvious you want it interpreted as

15*y
-------
5*y

Which simplifies to 3.

Your given equation however, simplified linearly = 15*y÷5*y
this simplifies to 3*y*y >> 3yy

When writing 15y ÷ 5y it is commonly assumed that 5y is the denominator, even though it technically needs parentheses. This logic should NOT be applied to the OP's question

6÷2(2+1)

In this case the answer is 3(3) = 9

reply to post by GobbledokTChipeater


fine but it is actually relevant. You wouldn't be arguing your points the way you are otherwise ...

reply to post by ASeeker343


Simplified it is just 3y. Not 3yy or anything else.... just 3y. It is also a problem that cannot be solved just simplified.

Wrong, simply wrong! y ÷ y = 1.

(15 * y) ÷ (5 * y) = 3. The "y"s "cancel each other out"

15 * y
------- = 3
5 * y

How do you get 3y??

There are 2 y's. Depending on how you write it they need to multiply or cancel, but you cant just throw one out. And yes its not a true equation, just an expression to be simplified. But so is the original question posed by the OP
