Verified answer

1) ΔA = 5*1 - 6*10 = -55.

ΔB = 6*2 - 5*10 = -38.

2) A + B = 11      11           A - B = -1       1

                20     3                        0      -1.

3)       А*В=(■(a&[email protected]&1))*(■(6&[email protected]&2))=

                 =(■(6a+10b&[email protected]+10&5c+2))

      B*A=(■(6&[email protected]&2))*(■(a&[email protected]&1))=

                 =(■(6a+5c&[email protected]+2c&10b+2))

4) A=■(5&[email protected]&1),B= ■(6&[email protected]&2).

  2A=■(10&[email protected]&2),3B= ■(18&[email protected]&6).

2A*3B= ■(10*18&12*[email protected]*15&2*6)=■(180&[email protected]&12).
