Answer 1

Salut,

e)100-100:100×[100+100:10-(100-75:25)=

=100-1×[100+10-(100-3)]=

=100-(110-97)=

=100-13=

=87

f)50+12×[214-240:(16-2×5)-10×100=

=50+12×(214-240:6)-1000=

=50+12×(214-40)-1000=

=50+12×174-1000=

=50+2088-1000=

=1138

g)110×10-[(599-99×4+30×5)+370:10]:10=

=1100-[(599-396+150)+37]:10=

=1100-(353+37):10=

=1100-390:10=

=1100-39=

=1061

h)(9×999-999:9):10-[444-6-(400-400:10)]=

=(9×999-999:9):10-[444-6-(400-40)]=

=(9×999-999:9):10-[444-6-360]=

=(9×999-999:9):10-[438-360]=

=(9×999-999:9):10-78=

=(8991-111):10-78=

=8880:10-78=

=888-78=

=810
