A = 32 + 4 - 3² + 7 x 3

A = 32 + 4 - 9 + 21

A = 36 - 9 + 21

A = 27 + 21

A = 48

B = 4 + (4 x -(17 - 12))

B = 4 + (4 x -5)

B = 4 + (-20)

B = -16

C = 2 - 3 x 4 / 2³ - 2 x 5

C = 2 - 12 / 8 - 10

C = -10 / -2

C = 5

D = (2 - 3)² x 4 / 8 - 10 x 2

D = (-1)² x 4 / 8 - 20

D = 1 x 4 / 8 - 20

D = 4 / -12

D = - 1/3
