Since the original equation is NOT 48/(2(9+3)), it cannot mean
48
2(9+3)
The original equation is 48/2(9+3), which means
48 *(9+3)
2
Correct...
Alacran u keep thinking the answer is 2, that means u r putting the extra parenthesis on the equation, but since the equation doesn't have the parenthesis the this means is 288.
Just go to the link that I provided, the calculator, and do it...
Or any calculator.
the calculator on the right is right...
The calculator on the left is wrong.. just put it on excel or on the online calculator, also you should check the settings on the one on the left..
I have the same calculator on the left and it gives me 288, go figure.
It's a faulty expression, probably composed by somebody intending to create an enigma. Any proper algebraist would have expressed it in one of the following two ways:
(48/2)(9+3) = 288
Or
48/[2(9+3)]=2
That's what parentheses are for, and are an integral part of algebraic expression. Leaving out the necessary parentheses is as fatal as leaving out the + sign.
If the person who wrote the expression doesn't know how to properly use algebraic terms, he has no business demanding that others guess what he means. The symbol " ÷ " is inappropriate in an algebraic expression anyway, it should have been " / ", and that itself is proof that the problem was composed by someone who didn't know anything about algebra. But nevertheless, it is badly and ambiguously parenthesized, and it is the responsibility of the person writing the equation to do it correctly and unambiguously, and whoever that was, failed. Proof of that is the mere fact that we are having this discussion.
jtur88 is right, the problem is written in poor fashion. It is intentionally written to be vague and cause confusion. Nobody with a strong background in math would have ever written the expression that way. That is what parentheses, brackets and braces are used for...to provide clarity on how the problem was intended to be interpreted.
