In my previous two math classes I'd get the answer wrong if I put the number first then the variable as my answer. Now in this class this way of doing it is wrong. I'm seriously confused now. For instance the last two classes said that it was standard practice to write an answer like: 3x+4. This class doesn't say it's standard or even that I should write. It as: 4+3x. I'm confused, which is more usually done? I like 3x+4 because to me things are more obvious when written that way, 4+3x doesn't show me anything. I'm going to come out of this class completely confused, and don't know which I should assume would be a right answer?
