oii

1000-[(2.4-6) + (2+6.4)]

=1000-[(8-6) + (2+24)]

=1000-[ 2 + 26]

=1000 - 28

= 972

B) 60+2. {[4. (6+2) -10] +12}

=60+2. {[4. (8) -10] +12}

=60+2. {[ 32 -10] +12}

=60+2. {[ 22] +12}

=60+2. { 34}

= 60 + 68

= 128

C) [(4+16.2).5 -10] .100

=[(4+32).5 -10] .100

=[(36).5 -10] .100

=[ 180 -10] .100

= 170 .100

= 17.000

D) {10+[5. (4+2.5) -8] .2} -100

= {10+[5. (4+10) -8] .2} -100

= {10+[5. (14) -8] .2} -100

= {10+[70 -8] .2} -100

= {10+ 62 .2} -100

= {10+ 124} -100

={ 134} - 100

= 34

E) 80-5 . (28-6.4) + 6 - 3 .4

=80-5 . (28-24) + 6 - 12

=80-5 . (4) + 6 - 12

=80-20 + 6 - 12

= 54
