The aim of the exercise is to create a single line of mathematics representing a matrix-vector multiplication. The line begins with:
Ax =
where the A and x are typeset in a bold italic maths font, (since A represents a matrix and x represents a vector.) Then follows a 2 by 2 matrix surrounded by round brackets. The first row reads:
0 1
The second row reads:
2 3
Next follows a column vector surrounded by round brackets. The first element is 1 the second is 2. Next follows an equal sign and then another column vector surrounded by round brackets. This vector has elements 2 and 8. The line of maths ends with:
= y
where y is typeset in a bold italic maths font.
