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

$\var{a}+\var{b}=$ a+b

Advice

(a)

$\var{a}+\var{b}=\var{u}$

Just add corresponding elements together.

(b)

$\var{p}\var{c}-\var{q}\var{d}$

Multiply each element of the first matrix by $\var{p}$ ...

$\var{p}\var{c}=\var{pc}$

...and multiply each element of the second matrix by $\var{q}$ .

$\var{q}\var{d}=\var{qd}$

Finally, subtract corresponding elements

$\var{p}\var{c}-\var{q}\var{d}=\var{pc}-\var{qd}=\var{v}$

Give a worked solution to the whole question.
