Question 647484: I'm sorry, but question 14557 is answered incorrectly if the problem is as stated. As it appears on screen in the solution by elima, the correct solution is n= -(1/32). I don't need a reply so you can just label me as a kook. Answer by Edwin McCravy(20060) (Show Source):
It all depends on whether the letter n is in the denominator or not:
If it is this way
14 - n = 22
The solution is -32.
-----------------------
However, if it is this way
14 - = 22
The solution is
So you are considering the n to be in the denominator.

Copied exactly as it was given in 14557
14-1/4*n=22
The order of operations (PEMDAS) say that division and multiplication are
taken by whichever comes first, so when you check it with -32
in the order of operations:
14-1/4*(-32) = 22
We do the division of 1 by 4 first and get .25, because the division
comes first going left to right.
14-.25*(-32) = 22
Next we do the multiplication:
14+8 = 22
22 = 22
So -32 is correct by the order of operations.
