Answer 1

[(60 : 6 + 20) + 25] : 5 =
= [(10 + 20) + 25] : 5 =
= (30 + 25) : 5=
= 55 : 5 =
= 11

900 + 300 : 10 - [ 76 + (290 - 206)] =
=900 + 30 - (76 + 84)=
=900 + 30 - 160=
=1200 - 160=
=1040

[(10 : 10 + 4) : 5 + 9] × 1000 + 700 : 100 + 11 × 8 =
=[(1 + 4) : 5] × 1000 + 7 + 88=
=(5 : 5) × 1000 + 95 =
=1 × 1000 + 95 =
=1000 + 95 =
=1095

[420 : (160 - 500 : 4) + 25 × 4] × 100 =
= [420 : (160 - 125) + 100] × 100 =
= (420 : 35 + 100) × 100 =
= (12 + 100) × 100 =
= 112 × 100 =
= 11200

[20 × (8 - 100 : 25) + 2 × 10] : 10 + 17 × 100 =
= [20 × (8 - 4) + 20] : 10 + 1700 =
= (20 × 4 + 20) : 10 + 1700 =
= (20 × 5) : 10 + 1700 =
= 100 : 10 + 1700 =
= 10 + 1700 =
= 1710
