From left to right? what the hell you tlaking about....

Take first elemntary book and you see that in this math you have to do () first... sicne 2 stands before () means you must multiply every single sign inside the  () with 2 ..

You say that first you multiply then you divide ?
YES this is the part they couldn't understand, 2(12)=2*12 is multiplication, so it must be done before the 48/.
From left to right? what the hell you tlaking about....

Take first elemntary book and you see that in this math you have to do () first... sicne 2 stands before () means you must multiply every single sign inside the  () with 2 ..
and this is true, it works from left to right. and we already do the operation in () first, then, remaining operations are multiply and divide, they are same priority so go from left to right.

Anyone Learnt PEDMAS It goes like this
terms inside parentheses or brackets
exponents and roots
multiplication and division
addition and subtraction
which means multiplication and division have same priority(same as exponents and root and addition and substraction)
Which means Divide and multiply are in same order you do it from left to right
About those things in elementary school it goes like this
2(9+3) = (2*9+3*2)
but in this case 48/2(9+3)
24(9+3)
(9*24+3*24)

I'm heretic for telling the truth there is a article in wikipedia about pedmas which proves that the solution is 288,it's not my fault people are still in elementary school or that they don't know simplest rule
...

I really got sick of those guys there talking about math, universities and how u are good at math.
Half of u there are 16-17 years old and havent even graduated yet.

Go sleep clever guys

It seems like my previous explanation was not enough for u guys, ill try to make it easier for u guys to understand why answer is 2.

So lets think of the number 24; 24 = 18+6 right?

Now lets write "18+6" in parenthesis of 2 which leads us to 2(9+3)

Now if you have completed elementary school you should be able to understand that 2(9+3) is an entire statement and it CANNOT be broken up.

So lets get back to 48/2(9+3)

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

I hope everyone can uderstand now. In this case Left to right thing doesnt work.

2(9+3) is fuckin sentence in math language

when space between 2 and "( means automatically as multplying factor when it comes to further calculations

therefore u leave 48 dividing "that sentence" at the end of fuckin calculations which means fuckin
48/24


so far i saw all noobs in dota said 288 xDD

so yeah stick to school not dota plz.
And dying in your bed many years from now, would you be willing to trade all the days from this day to that for one chance, just one chance, to come back here as young men and tell our enemies that they may take our lives but they will never take our freedom!

that's not an explanation.
number 24 can be wrote down as a 48/2 which is also part of equatiation.


Also 48/2 can be written down as a 48x0.5

so there should be no talking about priorites in dividing and  multiplying.
