Math: 6÷2(1+2) = ?

"2 people have one apple each and get two more each

They want to evenly divide their combined apples to 6 people so how many apples does each person get?"

Is there a different equation for this that would work better than 6÷2(1+2) = ?

Lol, I am Irish (descent) and extremely stubborn, I will give you that. But you are just as bad as 9 is the correct answer and yes the equation is flawed as well.

haha no explanations. Just claims. keep talking.

so "who won" (p81) was a stupid question. 12 more pages of repeating statements that don't differ from those in the 80 pages before that.

lol.

Actually, the Fibonacci sequence is rather easy to understand.

Just add the previous two numbers and keep going.

Keep typing and you'll remove all doubt that you are an imbecile.

The correct answer is:












George W. Bush = Barak Obama = Mitt Romney

haha Ok, great you understand it. Now use it to equate the things around you. DO you even know what the equation is called that they use for the sequence? Calling the sequence simple shows how much of it you do not understand.. Shallow.

Nvm nobody answers so here is THE answer:


log_2n 1944 = log_n (486 √2)
=> log_2 1944 / log_2 (2n) = log_2 (486 √2) / log_2 n
=> log_2 1944 / (1 + log_2 n) = (log_2 486 + 1/2) / log_2 n
=> log_2 1944 log_2 n = (log_2 486 + 1/2) (log_2 n + 1)
=> (log_2 1944 - log_2 486 - 1/2) log_2 n = log_2 486 + 1/2
=> (log_2 4 - 1/2) log_2 n = log_2 486 + 1/2
=> log_2 n = 2/3 log_2 486 + 1/3
=> log_2 n^6 = 6 log_2 n = 4 log_2 486 + 2
=> n^6 = 486^4 . 2^2
= 2^6 . 3^20
= 223154201664.

Did you really expect anyone responding to that?

They can't even "agree" wether 6÷2(1+2) is one or nine.

Is the glass half full or half empty?

Haven't read all the previous pages but when solving an equation
one uses BODMAS.
This is an acronym for
B.......Brackets
O.......Of
D.......Division
M.......Minus
A.......Addition
S.......Subtraction

So, first the Brackets..1+2=3
now we have 6/2x3
now the "of" which is 2x3=6
now we have 6/6
Do the Division and 6 divided by 6=1
Q.E.D.

This is old, and the answers STILL 9!!!!!!!!!!!!!!!!!!!!!!!

The answer is 1.

Its all about the parenthesis. Those of you getting 9 are forgetting that when you are left with 6/2(3) you still have parenthesis around the 3 which have to be dealt with first before you divide. They don't just magically disappear.

Still not convinced, 2(1+2) can also be expressed as (2*1)+(2*2) which I think we can all agree on =6, so 6/6=1

I'm sure someone has already mentioned this earlier, but I'm not about to check 80+ pages of math comments.

9

almost right..

Rule 1: First perform any calculations inside parentheses.
Rule 2: Next perform all multiplications and divisions, working from left to right.
Rule 3: Lastly, perform all additions and subtractions, working from left to right.

6÷2(1+2) = ?
6÷2*(3) = ?
6÷2 = 3 * 3 = 9

Too many pages have passed since the word obelus was mentioned

So here it is again:

obelus.

Ha, I was dumb back then. It's 1. P.E.M.D.A.S. is the order of operations.

Please excuse my dear Aunt Sally.

You both realize it is either or first right?

Elaborate please.

"A common technique for remembering the order of operations is the abbreviation "PEMDAS", which is turned into the phrase "Please Excuse My Dear Aunt Sally". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction". This tells you the ranks of the operations: Parentheses outrank exponents, which outrank multiplication and division (but multiplication and division are at the same rank), and these two outrank addition and subtraction (which are together on the bottom rank). When you have a bunch of operations of the same rank, you just operate from left to right. For instance, 15 ÷ 3 × 4 is not 15 ÷ 12, but is rather 5 × 4, because, going from left to right, you get to the division first. If you're not sure of this, test it in your calculator, which has been programmed with the Order of Operations hierarchy. For instance, typesetting this into a graphing calculator, you will get:"

Yes, but you do the multiplication FIRST.
That's the rule.

The answer is 1.

Poo brain.

MATH ONLY HAS ONE SET OF RULES.

LOOK AT THE LINK ABOVE..

MULTIPLICATION AND DIVISION ARE THE SAME STEP. YOU WORK THIS STEP LEFT TO RIGHT.

YOU CAN NOT STICK YOUR PHILOSOPHY INTO MATH. IT DOES NOT WORK THAT WAY. YOU DON"T LIKE IT? MAKE UP YOUR OWN SET OF NUMBERS AND RULES!

It is 1

6/ 2(1+2)

2*1=2
2*2=4

6/6=1

6 divided by 2 can also be written 6 over 1 times 1 over two. Now remove the brackets. 1\2 times 1 equals 1/2. 1\2 times 2 equals 1. 1\2 plus 2 equals 3\2 and times that by 6 since you already changed the division to times and added the recipcal of 2. 6\1 times 3\2 equaqls 18/2 which reduces to 9.

Write the equation like this (1 plus 2) 6 divided by 2.
Use six to remove the brackets but don't forget to change your division to times and add the recipical of 2 first. The answer is 9. but I dropped out of math. So I could be wrong but 9 checks multiple ways. Do I win the potatoes and bananas.

morons its 1

you can get 1 in more ways than 9

6/2(1+2)=
6/2+4=
6/6=1

by the current rules you dived and times before adding and subtracting 6\2 equals 3 plus e equals seven. I think the point here is to call out the flaw in properties...i don't know.

Precedence matters... parentheses take precedence in order of operation:

6/2(1+2) = ?

Parans first:

6/2(1+2) = 6/2(3)

Division and multiplication have equal precedence in order of operation so from left to right the division operation comes first:

6/2(1+2) = 3(3)

Finally multiplication:

6/2(1+2) = 9


----------------------

To get the result of 1 you would need something like this:

6/(2(1+2)) = 6/(2(3))
6/6 = 1

This is wrong.

----------------------

C++ Implementation
-------------------------

#include <iostream>

using namespace std;

int main(void)
{
int result = 6 / 2 * (1 + 2);
cout << "result = " << result << endl;

return 0;
}


When run the result is 9.

This is simple math. Where are the variables?
However if this was 6/2(1+2x) then you could use the FOIL method easily enough. We are only dealing with the simple order of operations here.
