Ya I was never that good at math but to get his answer wouldn't it have to look like this:
(6x8)-(5+9)
Yes. What the question really looks like, if you were to use brackets in that way, is this:
(6*8)+(-5+9)
On another note, it really should be PEDMAS, because those are parentheses, not brackets. Brackets are for other things.
Perhaps, but what our friend Trick did was group it this way:
(6x8)(-5+9)
He then arbitrarily inserted a "+" between the subsets. Now I understand there is "new" math and "old" math (which perhaps goes towards 'splaining why the world is the way it is), but in my day two subsets arranged this way inferred they were to be multiplied. Thus 48x4 = 192............
It's not arbitrary... When you have + or - sign it's because the number is positive or negative. So when it's - 5 + 9 it's going to make it a positive number, thus turning it into a + sign not a - sign. There is no new and old math. There is just smart and stupid people.
