I know this drove me crazy until someone finally explained it to me a while back, I had definitely learned it the wrong way.

But here's the problem with the parentheses either explicitly added or left off, as it should be since / is equivalent to divsion and not to a fraction bar.

6/[2(2+1] = Six

**over**twice the sum of two plus one.

6/[2(2+1)] = 6/[2(3)] = 6/(2*3) = 6/6 = 1

Six divided by two multiplied by the sum of two plus one.

6/2(2+1) = 6/2(3) = 3(3) = 9

Also, in other news I took the GRE today and by the looks of it I'm going to grad school. Go me.

Also: Holy crap! Where'd those two extra pages come from. Guess that goes in the glitch pile unless you've all been posting non-stop since I started typing. Unless I acidentally left a tab open for days... if so, my bad.
