答案和解析
1000-7除以5+2x6的立方+500除以7-200
=1000-7÷5+2x6³+500÷7-200
=1000-7/5+2x216+500/7-200
=1000-7/5+432+500/7-200
=1000+432-200-7/5+500/7
=1232-(1+2/5)+(71+3/7)
=1232-1-2/5+71+3/7
=1232-1+71-2/5+3/7
=1302+3/7-2/5
=1302+15/35-14/35
=1302+1/35
=1000-7÷5+2x6³+500÷7-200
=1000-7/5+2x216+500/7-200
=1000-7/5+432+500/7-200
=1000+432-200-7/5+500/7
=1232-(1+2/5)+(71+3/7)
=1232-1-2/5+71+3/7
=1232-1+71-2/5+3/7
=1302+3/7-2/5
=1302+15/35-14/35
=1302+1/35
