BODMAS is Brackets-Orders-Division-Multiplication-Addition-Subtraction

(9+3)48/2 = (12)48/2 = (12)24 = 288

If the answer was 2 the equation would look like this.
48/(2(9 + 3))

In BODMAS and PLEMDAS multiplication and division are of the same level of importance. Same as addition subtraction they are just acted upon from left to right. The / however implies it's a fraction not just normal division so the denominator is 2(9+3). Which is 24 which makes the fraction 48 over 24 which equals 2

yep and if you take the equation from left to right you will get 288. The 2 is NOT in parenthesis so therefor it can not go first.

Like I stated before if the equation was

48/(2(9+3)) Then it would equal 2, but the 2 is not included in the parenthesis so after the (9+3) you must go from left to right.

I think it really all comes down to what you were taught in school. In Calc 3 I was taught the L2R over the PLEMDAS.

There we go. That right there just hit it on the nose. Exactly what I left out when i made my last message.

There is no going left to right when the whole 2(9+3) is the denominator. I see it that way at least

This is actually a serious debate by some major mathematicians, so there is no way to tell who is correct and who is wrong at this point

try PEMDAS: Parenthesis, exponents, multiplecation, division, addition, and subtraction. the answer comes to 288. but it also depends on if it is a fraction, or a division sign. either answer would be right but if you use PEMDAS the answer will be 288. if in order of opperations, it will be 2.
