A)

$( + 2) \times ( - 10) \\ - (2 \times 10) \\ \boxed{ \blue{ = - 20}}$

B)

$( + 3) \times ( - 5) \\ - (3 \times 5) \\ \boxed{ \blue{ = - 15}}$

C)

$( - 5) \times ( + 1) \\ 5 \times 1 \\ \boxed{ \blue{ = - 5}}$

D)

$( - 1) - ( - 7) \\ - 1 - ( - 7) \\ - 1 + 7 \\ \boxed{ \blue{ = 6}}$

E)

$0 \times ( - 3) \\ - (0 \times 3) \\ \boxed{ \blue{ = 0}}$

F)

$( + 12) \times ( - 5) \\ - (12 \times 5) \\ \boxed{ \blue{ = - 60}}$
