  • S + M = (2 ... 0) + (1 ... 2) = (3 ... 2)
    .............. (-1 .. 3) ... (0 .. -3) . (-1 ... 0)

    (S + M)^2 = (3 ... 2) (3 ... 2) = (9 - 2 ...... 6 + 0) = (7 ... 6)
    ..................... (-1 .. 0) (-1 .. 0) ... (-3 + 0 .. -2 + 0) .. (-3 .. -2)

    S - M = (2 ... 0) - (1 ... 2) = (1 ... -2)
    ............. (-1 .. 3) .. (0 .. -3) . (-1 .. 6)

    (S - M)^2 = (1 .. -2) (1 ... -2) = (1 + 2 ... -2 - 12) = (3 ... -14)
    .................... (-1 .. 6) (-1 .. 6) .. (-1 - 6 ... 2 + 36) .. (-7 ... 38)

    f(S, M) = S^2 - M^2
    f(S + M, S - M) = (S + M)^2 - (S - M)^2
    = (7 ..... 6) - (3 ... -14)
    .. (-3 .. -2) .. (-7 ... 38)

    = (4 ... 20)
    .. (4 ... -40)
