Matrices?  Matrices do not equal to numbers.  Do you mean determinants?:

abs%28matrix%282%2C2%2C+11%2C4%2C7%2C3%29%29 = 11·3 - 4·7 = 33 - 28 = 5

abs%28matrix%282%2C2%2C+5%2C4%2C4%2C5%29%29 = 5·5 - 4·4 = 25 - 16 = 9

abs%28matrix%282%2C2%2C+7%2C6%2C3%2C4%29%29 = 7·4 - 6·3 = 28 - 18 = 10

abs%28matrix%282%2C2%2C+4%2C-2%2C2%2C2%29%29 = 4·2 - (-2)·2 = 8 + 4 = 12

abs%28matrix%282%2C2%2C+6%2C0%2C0%2C1%29%29 = 6·1 - 0·0 = 6 - 0 = 6

abs%28matrix%282%2C2%2C+-3%2C-9%2C5%2C9%29%29 = -3·9 - (-9)·5 = -27 + 45 = 18.
