Description

Sum of vectors v and w

Describe what this variable represents, and list any assumptions made about its value.

Can an exam override the value of this variable?

Generated value: `vector`

vector(-3,4)

← Depends on:

This variable doesn't seem to be used anywhere.

Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

Calculate $\var{v} + \var{w}=$ Gap 0.

Advice

We can add any two vectors which have the same size. To add the vectors, we add each entry separately.

$\var{v}+\var{w}=\begin{pmatrix}\simplify[]{{v[0]}+{w[0]}} \\ \simplify[]{{v[1]}+{w[1]}} \end{pmatrix} = \var{vectorsum}$

$\var{v}+\var{w}=\begin{pmatrix}\simplify[]{{v[0]}+{w[0]}} \\ \simplify[]{{v[1]}+{w[1]}} \\\simplify[]{{v[2]}+{w[2]}} \end{pmatrix} = \var{vectorsum}$

$\var{v}+\var{w}=\begin{pmatrix}\simplify[]{{v[0]}+{w[0]}} \\ \simplify[]{{v[1]}+{w[1]}} \\\simplify[]{{v[2]}+{w[2]}} \\\simplify[]{{v[3]}+{w[3]}} \end{pmatrix} = \var{vectorsum}$

$\var{v}+\var{w}=\begin{pmatrix}\simplify[]{{v[0]}+{w[0]}} \\ \simplify[]{{v[1]}+{w[1]}} \\\simplify[]{{v[2]}+{w[2]}} \\\simplify[]{{v[3]}+{w[3]}} \\ \simplify[]{{v[4]}+{w[4]}} \end{pmatrix} = \var{vectorsum}$
