Answer 1

Salutare!

a)

(425:5+129×4+2):3×4-127×6+2×29=

(85+516+2):3×4-762+58=

(601+2):3×4-762+58=

603:3×4-762+58=

201×4-762+58=

804-763+58=

42+58=

100

b)

144:3×9-(57×8-97×4+824:4+39×4)=

48×9-(456-388+206+156)=

432-(68+206+156)=

432-(274+156)=

432-430=

2

c)

(543:3+171:9):5+(651:3+3×128+400:100):5=

(181+19):5+(217+384+4):5=

200:5+(601+4):5=

40+605:5=

40+121=

161

d)

981:3-[164+(248:8+4×39+117:9):10]=

327-[164+(31+156+13):10]=

327-[164+(187+13):10]=

327-(164+200:10)=

327-(164+20)=

327-184=

143

e)

1-[107×5-(714:7-792:8)×178]=

1-[107×5-(102-99)×178]=

1-(107×5-3×178)=

1-(535-534)=

1-1=
