a) (607-388) x 8 - 92514 : 102
b) 113771 - 310 x 208
c) 7408 + 80407 + 400870 - 610 x 350
d) (16 400 : 80 - 2450 : 25) x 301

Answer 1

a) [(607-388) x 8] - (92514 : 102)

=[(219)x8] - (907)
=(1752)-(907)
=845

b) 113771 - (310 x 208)
= 113771 - 64480
49291

c) 7408 + 80407 + 400870 - (610 x 350)

= 488685 - (213500)
=275185

d) [(16 400 : 80) - (2450 : 25)] x 301
= (205)- (98) x 301
= 107 x 301
= 32207
