Explicație pas cu pas:

[(500 x 4 + 217 : 7) - (7 x 3 x 200 : 100 - 2 x 3 x 7)] x 3 = [(2000 + 217 : 7) - (7 × 3 × 200 : 100 - 2 × 3 × 7)] × 3 = [(2000 + 31) - (7 × 3 × 200 : 100 - 2 × 3 × 7)] × 3 = [2031 - (7 × 3 × 200 : 100 - 2 × 3 × 7)] × 3 = [2031 - (21 × 200 : 100 - 2 × 3 × 7)] × 3 = [2031 - (4200 : 100 - 2 × 3 × 7)] × 3 = [2031 - (42 - 2 × 3 × 7)] × 3 = [2031 - (42 - 6 × 7)] × 3 = [2031 - (42-42)] × 3 = (2031 - 0) × 3 = 2031 × 3 = 6093

Succese! :D

Answer 2

Salutare!

[(500×4+217:7)-(7×3×200:100-2×3×7)]×3 =

[(2000+31)-(21×200:100-6×7)]×3=

[(2031-(4200:100-42)]×3=

[2031-(42-42)]×3=

(2031-0)×3=

2031×3=
