F = (7 - 12 ) / ( -12 - ( -1-8x2))

F = ( -5 ) / ( -12 - ( -1 - 16))

F = -5 / ( -12 - ( -17))

F = -5 / ( -12 + 17 )

F = -5 / (5 )

F = -1

G = -20 + ( -3 x (-7-3)-16)

G = -20 + ( -3 x (-10) -16)

G = -20 + ( 30 - 16 )

G = -20 + ( 14 )

G = -20 + 14

G = -6

H = -5-2x(5-(5-13))

H = -5-2x(5-(-8))

H = -5-2x(5+8)

H = -5-2x(13)

H = -5-26

H = -31

I = (-3) x 12 + ( 1+ (-8) / 2 )

I = (-3) x 12 + ( 1 - 4 )

I = (-3) x 12 + ( - 3 )

I = (-3) x 12 - 3

I = -36 - 3

I = -39

J = -6 / (-3) -2x(1+3x(-8))

J = 2 -2x(1-24)

J = 2 - 2 x ( -23 )

J = 2 + 46

J = 48
