natsuki04 Q : -4 + 5 - (-4)
= -4 + 5 + 4
= -4 + 9
= 5

R: -14 - 7 x 3
= -14 - 21
= -35

S : (-5)x(-2)x(-3)x(-2)x(-4)
= (-10)x(-6)x(-4)
= (-10)x(-24)
= (-240)

T: (-5)+(-2)+(+3)x(-2)-(+4)
= (-5)+(-2)+(-6)-(+4)
= (-7)+(-10)
=(-17)

U: -2x4-6x(-5)
= -8+30
= 22

V= 12-2+5
= 12-7
= 5

W= 34-(17-12+6)
= 34- (17-18)
=34+1
= 35

X= [32-(-7+7x2)] - [8-(-20-2x4)]
= [ 32-(-7+14)] - [8-(-20-8)]
= [32+7] - [8+28]
= 39+36
= 75
