And again it's a 50/50 split. This is obviously the most difficult math problem ever conceived.- RJS

Yeah I understand that, but you re-wrote the problem. Like I stated above though, multiplication by juxtaposition supposedly takes priority before processing other operations. So wouldn't the answer to exactly how it's written really be 2?- RJS

I'm not saying your wrong, I just haven't seen the answer explained to my satisfaction yet. I see arguments from both sides backed up by sources so I'm getting confused. It's a pretty interesting problem though, seeing the division being nearly perfectly 50% on other polls is fascinating.- RJS

Ok, but then what do you take this statement to mean: The general consensus among math people is that "multiplication by juxtaposition" (that is, multiplying by just putting things next to each other, rather than using the "×" sign) indicates that the juxtaposed values must be multiplied...- RJS

I agree, but in this particular case, doesn't juxtaposition take precedence?- RJS

Looking at it like this though: 48 ÷ x(9 + 3) = 288 48 ÷ 9x + 3x = 288 48/12x = 288 4/x = 288 4 = 288x 4/288 = x 1/72 = x Would suggest that 288 is wrong, and that 2 is correct. Also, with the order of operations aren't we using the distributive property which states as an...- RJS

Every forum I've searched this on is split 50/50 between 2 and 288 as the answer. What is your consensus? People arguing PEMDAS say 288 But if you set the 2 in the equation to x and set the equation equal to 288, x then = 1/72. Thus proving 2 is the correct answer. Thoughts?- RJS
