If i remember this right :

1. 9+3 (This is true meaning of ''Doing Brackets first'' , not all which is connected to them , just inside the brackets )
2. Division 48/2 is 24
3. 24 x 12 is 288 and it is my final answer.

right.
opperation order (* is before /)
reconsider.

man yes u must beat the number 2 with the Bracket then u continue calculating it

[Natura Sonoris]

And why that?

Rule is simple , first brackets BUT ONLY whats is inside of them . Then goes division , no matter what , and then you multiply. You think just because 2 stands along the brackets it should go that way. Anyone who has done proper math will say that division goes first no matter what , and rule for brackets , as i said is onyl for what is the brackets.

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.

This is only thing that bothers me and which i cant remember correctly.

And why that?

Rule is simple , first brackets BUT ONLY

if u saw 1st brackets then why dafaq ppl  still think that the answer is 288?


48/ 2 ( 9 + 3 )
48/ ( 18 + 6 )
48/ 24 = 2

[Natura Sonoris]

I said 2x times.

Brackets rule applies for things ONLY INSIDE the brackets.  You cant say that

48 / (2x(9+3) and 48/2x(9+3) is same thing.

"working from left to right" is for those who didnt passed on math

EDIT: nvm,ill come tommorow with full explanation if i have time

"working from left to right" is for those who didnt passed on math

Still it is the rule in math. And it is logic that you do left to right , like the way you read ( there are exceptions in arabic )

I see that king wrote same thing

Lol i wasn't even thinking, dividing has an advantage over multiplying and brackets are done so it would be 2 if it was like this
48/(2(9+3))
btw gmx you're doing pitagoras theorem?

ofc man,working from left to right is true,but also apply that with working with correct opperation order

[Natura Sonoris]

You say that first you multiply then you divide ?

[pHu^^thAi]

ofc man,basics mathlab knowlage

[Natura Sonoris]

From what i learned , it was always divide. Btw , you cant compare programs and real life , it is not really same thing even it looks like.
