Tanuj,
We might both be right. I'll just ask my math teacher to make sure tho.

hard in math

Anyone else find that line extremely funny?

yeah...but I chose to ignore it...

in BEDMAN and PEDMAS

Nice. You just butchered two harmless acronyms. j/k

[ACman]

in BEDMAN and PEDMAS its this, Divi or Multi, which ever comes first, Add or sub, which ever comes first, but you must follow the rule of bracets and exponents

[indian airlines]

End of matter - Always use brackets!

Edit: and even though the left-right rule may be right, there is NO such instance where the "first division, then multiplication" rule doesn't work. Both of us are right.

8+4/4*3/2

How about that?

I say the answer is 9.5

Going by your logic it should be 4.5

The TI-83 seems to think I'm right.

4/4 = 1
1 x 3 = 3
3/2 = 3/2
8+3/2 = 19/2 = 9.5

Look at any math textbook...the order is:

1) Brackets
2) Exponents
3) Divison/Muliplication - As they appear from left to right
4) Addition/Subtraction - As they appear from left to right

I can't believe we are spending so long arguing a FACT!

Check above Will.

[Crazy764]

I'm pretty sure it's always "first division, then multiplication".

How did you pass highschool math Tanuj!

8+4/4*3/2

How about that?

I say the answer is 9.5 (by first doing the divisions, then the multiplication and finally the addition).

Going by your logic of left to right it should be 4.5

The TI-83 seems to think I'm right.

[FlyCharlestonSC]

No--it's definitely left to right. Not division first
let's say you have:
8/2*4*3*6/2
it equals 144 on my Ti-83
If you separate each step, it still equals 144


Just like addition and subtraction...left to right. (although that doesn't matter because it's commutative as long as you are adding negative numbers instead of subtracting positive numbers)

[indian airlines]

calculators mess things up like that....

Trust me. The rule is that mulitplication and division are NOT interchangeable. They are done in the order as they appear from left to right.

Yeah, they are definitely not interchangeable. Not sure about the left-right thing though. I'm pretty sure it's always "first division, then multiplication".

its like adding and subtraction, they are interchangeable. if you do 2+4-3, 6-3 is the same as 2+1. 3*10/5: 30/5, or 3*2

Not really.

3/6*2 (by BEDMAS) = 1

3/6*2 (by PEMDAS) = 1/4

Actually, division and multiplication are to be done in the order as they appear in the equation.

Therefore, in this question, 3 divided by 6, then times 2, would provide the correct answer, which is 1.

Try it in a calculator. Type the question into it without any brackets, you should get 1.
