# How do I add Vectors in Vector Calculus?

For example:

Suppose vector $u = (-2,3)$ and

vector $v = (-5,3)$ then:

$(u + v = ?)$ and

$(u - v = ?)$ and

$(v - u = ?)$ and

$(6u = ?)$ and

$(-1/8v = ?)$ and

$(3u - 4v = ?)$

You have been posting for at least two months, have posted seven questions, and accepted none of the replies you have received. Not very community-minded... – Arturo Magidin Jan 25 '11 at 5:22
Before you decide to go ad hominem on another person, please be correct. I have been thankful and happy with many answers I've received. If you have a personal pique against how I word questions or responses, please keep it to yourself unless there's a way to message me personally or you're going to contribute to the community with your response. Other students, who are striving to learn, will ask similar questions. Pertinent responses from other users are ideal. – Math Student Jan 25 '11 at 5:47
So why haven't you accepted any of the answers as correct? – arsmath Jan 25 '11 at 6:52
