简算:12.34+23.41+34.12+41.23简算:12.34+23.41+34.12+41.23简算:12.34+23.41+34.12+41.2312.34+23.41+34.12+41.2

简算:12.34+23.41+34.12+41.23
简算:12.34+23.41+34.12+41.23

简算:12.34+23.41+34.12+41.23
12.34+23.41+34.12+41.23
=(12+23+34+41)+(0.34+0.41+0.12+0.23)
=100+1
=101

各位都是1234相加,所以=111.10=111.1 。
LS明显是错误的,12+23+34+41是=110拜托。

个位、十分、小数点后同位相加,即:1+2+3+4=10,同理,全向前进1,就是:111.10
