简便计算方法如下:
35+295+29993+299992+2999991
=5+6+7+8+9+295+29993+299992+2999991
=(295+5)+(7+29993)+(8+299992)+(9+2999991)+6
=300+30000+300000+3000000+6
=3330306

35+295+29993+299992+2999991
=35+(300-5)+(30000-7)+(300000-8)
+(3000000-9)
=35+300+30000+300000+3000000-(5+7+8+9)
=3330335-29
=3330306

(35-5)+(295+5)+(2994+6)+(29993+7)+(299992+8)+(2999991+9)
=30+300+3000+30000+300000+3000000
=3330+30000+300000+3000000
=33330+300000+3000000
=333330+3000000
=3333300
