42:7x8-6x(3+5)=0
42:7x(8-6)x(3+5)=96
(42:7x8)-(6x3+5)=35
(42:7)x((8-6)x3)+5=41
42:7x(8-6)x(3+5)=96
(42:7x8)-(6x3+5)=35
(42:7)x((8-6)x3)+5=41
42 : 7 × 8 – 6 × (3 + 5) = 6 × 8 - 6 × 8 = 48 - 48 = 0
42 : 7 × 8 – 6 × 3 + 5 = 6 × 8 - 18 + 5 = 48 - 18 + 5 = 30 + 5 = 35
Aici nu sunt necesare paranteze.
42 : 7 × (8 – 6) × (3 + 5) = 6 × 2 × 8 = 12 × 8 = 96
(42 : 7) × (8 – 6) × 3 + 5 = 6 ×2 × 3 + 5 = 12 ×3 + 5 = 36 + 5 = 41
