A= 3+4x(-5)
A= 3+(-20)
A= -17

B= (3-3/(-3))x3
B= (3-(-1))x3
B= 4x3
B= 12

C= 6x(-5)+3x(-4)+10
C= -30+(-12)+10
C= -42+10
C= -32

D= (-5(-3))x(12/(-4))
D= -8x(-3)
D= 24

A = 3+4x(-5)
A = 3 - 20
A = -17

B = (3-3/(-3))x3
B = (3 - (-1)) x 3
B = 3 + 1 x 3
B = 4 x 3
B = 12

C = 6x(-5)+3x(-4)+10
C = -30 - 12 + 10
C = - 42 + 10
C = - 32

D = (-5(-3))x(12/(-4))
D = -8 x - 3
D = 24
