VA IMPLOR CÂT MAI REPEDE PUN PUNCTAJ MAXIM AI COROANA SI MULTUMESC
3 2 2 3 15 7 2
[(3 ) -25]:[(3 ) +2 :2 -5 ]

Answer 1

20·{4+10[120+20·(36-36:4)]} =
20{4+10[120+20(36-9)]} =
20{4+10[120+20•27]} =
20[4+10(120+540)] =
20(4+10•660) =
20(4+6600) =
20•6604 =
132080

La b) nu prea 3 bine redactat exercițiul.
(3-25):(3+2:2-5) =
(-22):(3+1-5)=
-22: (-1)=22

Answer 2

20·{4+10[120+20·(36-36:4)]}=
=20·{4+10[120+20·(36-9)]}=
=20·[4+10·(120+20·27)]=
=20·[4+10·(120+540)]=
=20·(4+10·660)=
=20·(4+6 600)=
=20·6 604=
=132 080
20·{4+10[120+20·(36-36:4)]}
   7    6   5      4    3     2   1   - ordinea efectuarii operatiilor

[(3 ) -25]:[(3 ) +2 :2 -5 ]=
=(-22):[3+1-5]=
=(-22):(-1)=
=22

[(3 ) -25]:[(3 ) +2 :2 -5 ]
       1    5       3   2   4 - ordinea efectuarii operatiilor
