Explicație pas cu pas:

18:3 + 5x(4-1) + 8:[2x(6-4)] - 18:(2+2x2) + 21:[2x(9:4,5)+3] + 48:(4+2x2)

= 6 + 5 x 3 + 8 : (2 x 2) - 18 : (2 + 4) + 21 : (2 x 2 + 3) + 48 : (4 + 4)

= 6 + 15 + 8 : 4 - 18 : 6 + 21 : 7 + 48 : 8

= 6 + 15 + 2 - 3 + 3 + 6

= 29

18:3+5×(4-1)+8:[2×(6-4)]-18:(2+2×2)+21:[2×(9:4,5)+3]+48:(4+2×2)=

=6+5×3+8:(2×2)-18:(2+4)+21:(2×2+3)+48:(4+4)

=6+15+8:4-18:6+21:(4+3)+48:8

=21+2-3+21:7+6

=23-3+3+6

=29
