Both my kids do very well at Math...and they both said 1...that's the way they were taught

BTW, guys...no need for the name calling

To be solved == 6/2(1+2)

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

2. 6/2x3

3. / means divided

4. Now it is 6/2x3

5. If it were (6/2)x3 then indeed the answer would be 9

6. However, it is 6 divided by 2x3, which is ONE.

my thinking

It would be 1 if it was written as 6/(2(1+2))

but the operation is 6 divided by 2 then times (1+2) = 9

Jango, Mits explained it here.

Unfortunately his presentation didn't answer my question,

you are aware i meant a set of numbers above a line and a different set of numbers below the line,although it meant division where this symbol [ / ] is used,the approach to solve is different when this symbol [ ÷ ] is used.

/ and ÷ mean the same thing. / is commonly used when writing with a computer because a lot of keyboards do not have the ÷ symbol. 

You will also see * used for X.

my thinking

6 / 2 X 3 = 9. 

2 X 3 / 6 = 1.

When multiplication and division are present in the same equation, you go from left to right since / and X are on the same level using PEMDAS rules.

Your kids either do not remember what they were taught or they were taught incorrectly.

Correct Raymond.

The operative part of this specific example is .. / .. the divide sign.

It means that the set of numbers before and after the divided sign are independently determined.

The result above is then divided by the result below.

Incorrect.

This might have been true when you went to school before 1917. We're in the 21st century now and PEMDAS rules prevail. When / and X are in the same equation, you proceed from left to right.

PEMDAS rules

How Do I Remember It All ... ? PEMDAS !

So do it this way:

Example: How do you work out 12 / 6 × 3 / 2 ?

Multiplication and Division rank equally, so just go left to right:

First 12 / 6 = 2, then 2 × 3 = 6, then 6 / 2 = 3

Professor Mars in all his glory.  

PEMDAS rules does not prevail.

I is basic math. It has to do with precedence  of operators.

The slop can jackasses will not know this.

1. Parentheses (simplify inside 'em)
2. Exponents
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

The answer is 1.

First solve the value in parenthesis then apply multiplication/division.

DG schooled the slop can crew.

The dumbest thing I heard all year. PEMDAS rules apply to every mathematical equation. They determine the order of operations. You can't just make up shit as you go along like you are doing in this case.

Maybe when you went to school 70 years ago they weren't applicable. They apply now. 

Seems like you also need some grammar lessons.

Ok Guys click on attachment,what is the answer.

Cant paste in body of post.

The answer to this is 1 but it's not the same as 6 / 2 X 3.

Thanks for conceding. DG stubborn like an ole mule though.

6 ÷ 2(2 + 1)

My bad of interpreting division symbol [ / ]

the answer is 9

Well my excuse is just returning from the pool with too much margarita in the system. Anyone dropping this formula in excel or any spreadsheet will see the result will be 9. 

I think Riffy started this thread deliberately to see who would concede.

Hey Guy this was in the age of the Dinosaurs. 

Mental math - answer is 9.

Why Mars keep saying PEMDAS  I was taught BOMDAS?

Is it a PEMDAS GT thing?

They both mean the same thing. BODMAS is the British equivalent of PEMDAS.

Brackets = Parentheses.

Orders = Exponents.

Rest In Peace Mr. Motilall, my late math teacher in Form 5.

That would be pre 1917....

You never disappoint girl!  For those who don't know, Alena wrote CXC Maths at age 14 and passed with distinction!   So did one of her sisters.

That is what caused all the riffraff. GNI folks here are trying to use the BOMDAS rule when they should be using the PEMDAS one. 

Y'all Berbicians does even use the BODMAS rule.

Note your sister said " Mental math". So, you are excused as well as Drugb, who had to use Excell to solve it.

Whoop ti do. I wrote GCE O Level Pure Math at 14 and got a distinction. So did many other students who were in the Math/Science stream. They did it this way so that you could write Additional Math in 5th form.

Chief, I remembered when the guy(DH?) got pinned under their tractor. His younger brother, who was my room mate at the time had to get permission to reenter the country. He was ona student visa also. This was in 1972?

1974 or 1975.

His younger brother now has a business in Minnesota .
