\[ egin{bmatrix} 1 & 2 & 3 \ 2 & 4 & 6 \ 3 & 6 & 9 nd{bmatrix} \]
which represents a 2x2 matrix.
For example, in a visual puzzle, a test-taker may need to identify a pattern in a matrix, such as:
\[ egin{vmatrix} a & b \ c & d nd{vmatrix} \]
\[ egin{bmatrix} 1 & 2 & 3 \ 2 & 4 & 6 \ 3 & 6 & 9 nd{bmatrix} \]
