Answer 1

a). 614-2*(40-27:3)

614-2*31

614-61=553

b). 1012-5*(9:3*3+202:2)

1012-5*(9+101)

1012-5*110

1012-550=462

c). (6*14-2)*(40-27:3)

82*31=3198

d). [(2*3²+3*2²):6+52]:5+10²

[(2*27+6):6+52]:5+10²

(60:6+52):5+10²

62:5+10²

12,4+100=112,4

Answer 2

Răspuns:

a) 614-2(40-9)=614-2*31=614-62=552

b) 1012-5(3*3+101)=1012-5(9+101)=1012-5*110)=1012-550=462

c) (84-2)(40-9)=82-41=41

d)[12+12):6+52]:5+100=24:6+52]:5+100=(4+52):5+100=59:5+100=9,28+100=109,28
