Explicație pas cu pas:

3*2*[(22+3*8):2+5]*10-[(9+9*9)*4-60]⁚5:6    

= 3*2*[(22+24):2+5]*10-[(9+81)*4-60]:5:6

= 3*2* [46⁚2+5]*10-[90*4-60]:5:6

=3*2*28*10-300:5:6

= 1680-10

1670

4*[(11-4)*(73-17*4)- 4*(1+20:5)]-3*(1+80:8)

= 4*[7*5-4*5]- 3*11

= 4*[35-20] -33

= 4* 15-33

= 60-33

= 27

800-720:4- [231: 3+5*(4*26+68)]

=800- 180- [ 77 +5*( 104+68)]

= 620 - [ 77+5* 172]

=620 – [77+ 860]

= 620 – 937

= - 317  

   [ 333*8 -333*3 - ( 333*21 – 6093 )]: 5

= [ 2664 – 999 - ( 6993 – 6093 )] : 5

= [ 1665 – 900 ] : 5

= 765 : 5  

= 153

  [ 3948 – 22 * ( 200 -462 : 7 )]: 5  

= [ 3948 – 22 * ( 200 – 66)] : 5

= [ 3948 -22* 134 ] : 5

= [ 3948 – 2948 ] :5

= 1000:5

= 200
