Question 18624: Alright, this one is starting to become an irritation at another board.
3a � 3b = x
a = 10, b = 2
Now, I solve this by satisfying the variable terms first, as such:
(3 * 10) � (3 * 2) = x
(30) � (6) = x
5 = x
The alternate solution that's being argued is that variable terms aren't solved first, and linear order of operations takes precedent:
3a � 3b = x
3 * 10 � 3 * 2 = x
30 � 3 * 2 = x
10 * 2 = x
20 = x
So, which is correct? I've scoured Google for this, but haven't found any confirmation either way.
