Răspuns:

Explicație pas cu pas:

9 + 3 × [ 6 - 2 × ( 12 - 2 × 5 ) ] = 15

= 9 + 3 × ( 6 - 2 × 2 ) =

= 9 + 3 × ( 6 - 4 ) =

15 - 2 × [ 12 - 3 × ( 10 - 2 × 2 - 4 ) ] = 3

= 15 - 2 × [ 12 - 3 × ( 10 - 4 - 4 ) ] =

= 15 - 2 × [ 12 - 3 × ( 6 - 4 ) ] =

= 15 - 2 × ( 12 - 3 × 2 ) =

= 15 - 2 × ( 12 - 6 ) =

= 15 - 2 × 6 =
