a/ 5.42 – 18 : 32
= 210- $\dfrac{9}{16}$
= $\dfrac{3351}{16}$
b/ 33.18 – 33. 10
= 33.( 18-10 )
= 33. 8
= 264
c/ 39. 213 + 87 . 39
= 39.( 213+87 )
= 39. 300
= 11 700
f/ 36: 32 + 23 . 22
= 1,125 + 506
= 507,125
g/ (-21) + (-24) + 35
= (-45)+35
= -10
h/ (-15) + 8 + (-34)
= -7 + (-34)
= -41
i/- (-229) + (-119) – 401
= 209 + (-119) – 401
= -( 209+401 )-119
= -610-119
= -729
k/ (-3).(-4).(-5)
= 12.( -5)
= -60
l/ (- 6 – 3).( – 6+ 3)
= (-9).(-3)
= 27
m/ (-4 – 14 ) : 3
= -18 : 3
= -6
n/ 18 .17 – 3.6.7
= 18 .17 – 18.7
= 18.( 17-7 )
= 18.10
= 180
p/ 33 . (17 – 5 ) -17 . ( 33 – 5 )
= 33. 12- 17.28
= -80
q/ 54 – 6 .(17 + 9)
= 54 – 6 .26
= 54 – 156
= -102
