10.000-{[(500×4+217:7)-(7×3×200:100-2×3×7)]×3}

Answer 1

10.000-{[(500×4+217:7)-(7×3×200:100-2×3×7)]×3} =

= 10000-{[(2000+31)-(21×2-42)]×3} =

= 10000-{[2031 - (42-42)]×3} =

= 10000-(2031 - 0)×3 =

= 10000-2031×3 =

= 10000-6093=

= 3907

Answer 2

10000–{[(500×4+217:7)–(7×3×200:100–2×3×7)]×3}
=10000–{[(2000+31)–(21×2–42)]}×3
=10000–[(2031–(42–42)]×3
=10000–(2031–0)×3
=10000–2031×3
=10000–6093
=3907
