  • How does this change the determinant of the Matrix?

    If I have the matrix (M) with the determinant det(M), and then i have the matrix M' which is:

    [            |0,0]

    [   M      |0,0]

    [            |0,0]

    [0, 0, t-1|,-1,0]

    [0, 0, t-1|,-1,t]

    would you have to take into consideration the [t-1]s? since they are directly "under" the M matrix. I put this into my calculator using placeholder numbers, and I got the determinant of M to be 9, and M' to be -9, when i substituted a -1 diagonally across from the original M matrix, even though I also added terms below the matrix. So although I'm confident that it doesn't change the determinant, I'm wondering WHY it doesn't.

  • If i rolled a dice, put a cup over the dice, and then asked you, "how much you wanna bet that this is a 6?"?

    would you assume that

    a) i thought there was a 6 under there

    b) i didn t think there was a 6 under there

    just a bet between me and my friends thanks brohemoth
