Question

5. Calculati a) –121+17:[(93:3+3):2].50 ; b) –2:{3-[-(2-3+6:2).(-2) – 7]}; c) -2-{2-3.[-6:3-9:03:1-12)]}.​

Answer 1

a) 93 : 3 = 31

31+3=34

34:2=17

17:17=1

1× 50= 50

-121+50=-71

b)6:2=3

-2-3=-5+3=-2

-2-7=-9×(-2)=18

3-18=-15 , Nu stiu daca e corect :( rezolvarea

c) -6:3=-2

9:03=3:1=3-12=-9

-2-9=-11

2-3=-1

-1×(-11)=11

-2-11=-13

nu sunt sigur daca b e corect :'
