Question

a, 67 + ( - 2018 ) +33 + 2018 - 189
b,  3.(-16) + (-12) + 60
c, ( 1974 + 647) - (1974 - 353 )
d, -24 : (-6) + (-3) mũ 2 - |-15| + (-2 ) mũ 3 - (-410)


 

Answer 1

a.67+( -2018)+33+2018-189

=[(-2018)+2018]+(67+33)-189

=0+100-189

=100-189

= -89

Answer 2

b.3.(-16) + (-12)+60

= -48+(-12)+60

=-60+60

=0

Answer 3

c.(1974+674) - (1974-353)

=1974+674-1974+353

=(1974-1974)+674+353

=0+674+353

=1027

Answer 4

d.-24:(-6)+(-3)²-I-15I+(-2)³-(-416)

=4+9-15+(-8)+416

=13-15+(-8)+416

= -2+(-8)+416

= -10+416=406

Answer 5

a) 67 + (-2018) + 33 + 2018 - 189 = (67 + 33) + (-2018 +2018) - 189 = 100 -189 = - 89

b) 3* (-16) + (-12) + 6 = -48 -12 + 60 = -60 + 60 = 0

c) (1974 + 647) - (1974 -353) = 1974 + 647 -1974 + 353 = (1974 - 1974) + (647 + 353) = 1000

d)-24 / (-6) + (-3) mũ 2 - I -15I + (-2) mũ 3 - (-410) = 4 + 9 - 15 - 8 + 410 = 400
