I gave you a quote and link to a math site even, that proves otherwise...
Where is your cited support for the contrary?
Because the number is against the parenthesis, this trumps the stand-alone division and multiplication and is perfectly within the order of operations
of the problem.
The real proof is to simply put it into a graphing calculator (that can account for the correct notation) and you will get the correct answer of 1. A
regular calculator does not have the programming logic to account for the notation.
Even this link is incorrect:
Because they are ignoring the hierarchy of doing the number next to the parentheses calculation first. It's called implied multiplication by
juxtaposition, which is to be carried out before division.
Of course, you could remove the ambiguity, by simply writing the problem correctly in the first place, with the appropriate parentheses or
Here's probably the best article on it, as it basically states that due to the problem being written ambiguously, you get ambiguous answers....
So, the REAL bottom line is that because of the way it is written, there is no ONE real definitive answer for it (as it is written), as implied
multiplication by juxtaposition is no longer considered a definitive standard (as it isn't needed if the problem is written with modern notation
methods). So, the problem is ambiguous, and so is the answer.
