25 ×2 + 10 ×5) + 9 × 8 ÷{ 56 + 3×[ 5 + 6×(3 ×4 -10 )-17]-5×4 }​

Răspuns :

3 × 4 - 10 = 12 - 10 = 2

5 + 6 × 2 - 17 = 5 + 12 - 17 = 0

= 56 + 3 × 0 = 56 + 0 = 56

= 5 × 4 = 20

Scădeți 20 din 56: 56 - 20 = 36

=(25 × 2 + 10 × 5) + 9 × 8 ÷ 36

= (50 + 50) + 9 × 8 ÷ 36

= 100 + 72 ÷ 36

= 100 + 2

= 102
