## Homework Statement

Hi, I have a really short (and dumb) question.

In one of my homework problems they talk about a vector w, such that w=e

_{1}+e

_{2}+e

_{3}. (In R

^{3}.)

## The Attempt at a Solution

I guess they mean that: e

_{1}=(1,0,0), e

_{2}=(0,1,0) and e

_{3}=(0,0,1). So w=(1,1,1). Right?
