Question

(6×8:4-20:5×3+6×7):(18:3:3+32:8)

Answer 1

(6×8:4-20:5×3+6×7):(18:3:3+32:8)=
(48:4-4×3+42):(6:3+4)=
(12-12+42):(2+4)=
(0+42):6=
42:6=7

Answer 2

☆ ( 6 × 8 ÷ 4 - 20 ÷ 5 × 3 + 6 × 7 ) ÷ ( 18 ÷ 3 ÷ 3 + 32 ÷ 8 ) = 7 ☆

Deoarece :

• 6 × 8 = 48
• 48 ÷ 4 = 12
• 20 ÷ 5 = 4
• 4 × 3 = 12
• 6 × 7 = 42
• 12 - 12 = 0
• 0 + 42 = 42
• 18 ÷ 3 = 6
• 6 ÷ 3 = 2
• 32 ÷ 8 = 4
• 2 ÷ 4 = 6
• 42 ÷ 6 = 7
