2, silly.


Why is 6 afraid of 7?

Because 7 - 8 - 9. Wink


Now go outside and get some sun

Because if you write it like a normal equation that is the answer.

48
2(9+3)

I thought the order of operations was PEMDAS,

parentheses
exponents
multiplication
division
addition and finally
subtraction

Answer

48
__ * (9+3) = 288
2


It's not 48/(2(9+3)) = 2

You are adding brackets that don't exist.
Either way, the equation is poorly written.

48�2(9+3)=288

...because:

48 � 2 (9 + 3) = 48 � 2 x (9+3) = 48 � 2 x (12) = 24 x (12) = 288

I could have dropped the parentheses once I added 9 and 3, because with the multiplication symbol, they are redundant. In order for 2 to be the solution, the formula would have to be written with additional parentheses:

48 � (2 (9 + 3)) = 48 � (2 x (9 + 3)) = 48 � (2 x (12)) = 48 � (24) = 2

So, RMNC and Google are right.

Did you even click the link? You are aware that tinyurl makes long URLs smaller, right?

Not to get too serious in this thread, but I read a math blog that was comparing elementary math textbooks today from ones in the early 21st century. At the time, kids spent a ton of energy solving variations of this math "problem" , which was a complete waste of time. If you really want computer-grade accuracy, then use Polish Notation, otherwise context is important.

So my vote? Both.

Something must be wrong on your end. That link for me goes to google.com's calculator, with the equation and answer as 288.
