A matrix of the form
(matrix%283%2C3%2C%0D%0AA%5B1%5D%2CA%5B2%5D%2CA%5B3%5D%2C%0D%0AB%5B1%5D%2CB%5B2%5D%2CB%5B3%5D%2C%0D%0AC%5B1%5D%2CC%5B2%5D%2CC%5B3%5D%29)
has a determinant,D, equal to
D=A%5B1%5D%2A%28B%5B2%5D%2AC%5B3%5D-B%5B3%5D%2AC%5B2%5D%29+%2B+A%5B2%5D%2A%28B%5B3%5D%2AC%5B1%5D-B%5B1%5D%2AC%5B3%5D%29+%2B+A%5B3%5D%2A%28B%5B1%5D%2AC%5B2%5D-B%5B2%5D%2AC%5B1%5D%29
D=4%2A%281%2A%28-3%29-%28-2%29%2A%28-4%29%29+%2B+%28-4%29%2A%28%28-2%29%2A%28-2%29-%28-1%29%2A%28-3%29%29+%2B+10%2A%28%28-1%29%2A%28-4%29-1%2A%28-2%29%29
D=4%2A%28-3-8%29+%2B+%28-4%29%2A%284-3%29+%2B+10%2A%284%2B2%29
D=-44+%2B+%28-4%29+%2B+60
D=12
