Question

30+50{32:8+5*[40+8*(15:5-2)]}:2.​

Answer 1

30 + 50*{32 : 8 + 5 * [40 + 8 * (15 : 5 - 2)]} : 2 =

= 30 + 50*{4 + 5 * [40 + 8 * (3 - 2)]} : 2 =

= 30 + 50*[4 + 5 * (40 + 8 * 1)] : 2 =

= 30 + 50 * [4 + 5 * (40 + 8)] : 2 =

= 30 + 50 * (4 + 5 * 48) : 2 =

= 30 + 50 * (4 + 240) : 2 =

= 30 + 50 * 244 : 2 =

= 30 + 50 * 122 =

= 30 + 6100 =

= 6130

R: 6130

Answer 2

30+50{32÷8+5×[40+8×(15÷5-2)]}÷2=202

30+50{32÷8+5×[40+8×(3-2)]}÷2=202

30+50{32÷8+5×(40+8×1}÷2=202

30+50{32÷8+5×(40+8)}÷2=202

30+50(32÷8+5×48)÷2=202

30+50(4+240)÷2=202

30+50+244÷2=202

30+50+122=202

80+122=202

30+50×122=6130

30+6100=6130
