❁ Rezolvare

Modul I

6 × ( 3 + 5 ) = 6 × 8 = 48

( 6 + 3 ) × 3 = 9 × 3 = 27

5 × ( 8 + 3 ) = 5 × 11 = 55

( 10 × 2 ) × 2 = 20 × 2 = 40

Modul I

6 × ( 3 + 5 ) = 6 × 3 + 6 × 5 = 18 + 30 = 48

( 6 + 3 ) × 3 = 6 × 3 + 3 × 3 = 18 + 9 = 27

5 × ( 8 + 3 ) = 5 × 8 + 5 × 3 = 40 + 15 = 55

( 10 × 2 ) × 2 = 10 × ( 2 × 2 ) = 10 × 4 = 40

❀ Succes! ❀
