Explicație pas cu pas:

1000-120:{75+225:[34-75:5-7x(48-322:7)]}=

1000-120:{75+225:[34-15-7x(48-46)]}=

1000-120:[75+225:(19-7x2)]=

1000-120:[75+225:(19-14)}=

1000-120:(75+225:5)=

1000-120:(75+45)=

1000-120:120=1000-1=999

deci..........

1)322:7=46

2)48-46=2

3)75:5=15

4)7x2=14

5)34-15=19

6)19-14=5

7)225:5=45

8)75+45=120

9)120:120=1

10)1000-1=999
