Gap-fill

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

$\mathbf{AB} = \var{A}\var{B} =$ Unnamed gap

Advice

$\begin{align} \mathbf{AB} &= \var{A}\var{B} \\ &= \begin{pmatrix} \simplify[]{ {a[0][0]}*{b[0][0]}+{a[0][1]}*{b[1][0]} } & \simplify[]{ {a[0][0]}*{b[0][1]} + {a[0][1]}*{b[1][1]} } \\ \simplify[]{ {a[1][0]}*{b[0][0]} + {a[1][1]}*{b[1][0]} } & \simplify[]{ {a[1][0]}*{b[0][1]} + {a[1][1]}*{b[1][1]} } \end{pmatrix} \\ &= \var{a*b} \end{align}$
