Explicație pas cu pas:

33124:2+123-[64x11-12+(11+6)+132:4]

16562+123-(704-12+17+33)

16685-742=15943

4+3x[50+3x(50-46)]

4+3x(50+3x6)

4+3x(50+18)

4+3x68

4+2004=2008

4+[4-(4+1x4-4)+a]:4=8

4+[4-(4+4-4)+a]:4=8

4+(4-4+a):4=8

4+a:4=8

a:4=8-4

a:4=4

a=4x4

a=16

8+6×[4+27:(0+u×9)]=49+10:10

8+6x(4+27:9u)=49+1

8+6x(4+3u)=50

8+24+18u=50

32+18u=50

18u=50-32

18u=18

u=18:18

u=1
