c) [(6208-108)-100]-5555=
d) 7911-[8211-(10100-5702)]
e) 12543-[1456-(9876-867)]

Answer 1

a) (217-1000)-17=

=-783-17

=- 800

b) 217-(100-17)=

=217-83

=134

c) [(6208-108)-100]-5555=

=(6100-100)-5555

=6000-5555

=445

 d) 7911-[8211-(10100-5702)]

=7911-[8211-4398]

=7911-3813

=4098

 e) 12543-[1456-(9876-867)]

=12543-(1456-9009)

=12543-(-7553)

=12543+7553

=20096

Answer 2

(217-100)-17=117-17=100
b) 217-(100-17)=217-83=134
c)[(6208-108)-100]-5555=(6100-100)-5555=6000-5555=445
d) 7911-[ 8211- ( 10100-5702)=7911-(8211-5498)=7911-2713=5198
