12.36-2.77+0.64-0.23=(12.36+0.64)-(2.77+0.23),
12.4÷0.25,
0.38+9.62÷3.7×5.4直接算!
8.6÷4.5——18.2÷7.3直接算!
[(5.84-3.9)÷0.4+0.15】×0.92直接算!
13.7×0.25-3.7÷4=13.7÷4-3.7÷4=(13.7-3.7)÷4

简缩句 求助
since i have been specially invited to speak,it is rude of you now to tell me that i can not do.书本说这句子有错.答案说是把can not do改为can not或can not do it.它解析说:句中的从句为简缩句,必须用主语+助动词的形式,如果不用简缩句,就必须在动词do后加上宾语.. 什么是简缩句,哪个从句是简缩句啊?还有答案说从句为简缩句,必须用主语+助动词的形式,那为什么要去掉do呢,do不是助动词吗?求解

that i can not do 是从句缩句.答案解析是对的呀,do 在这里是动词,不是助动词.do 在这里表示的意思是做什么,所以要用do it.

=2+8+14+.+1998+1994+2000-(5+11+17+.+1991+1997)=334*2+((334*333)/2)*6-(332*5+((332*331)/2)*6)=1001或者从2到2000只看加法的话是334个数(根据等差数列算出个数的),那么从8到2000就333个,而且每个加法都带一个减法,一加一减看作一个组的话,就有333个3就是999,再加上2就是1001

(1)原式=4(2.1-10.5*0.2)/5.75
=0
(2)原式=2.08(5.4 6.6-1)
=2.08*10
=20.8
原式=10.1*9.2-0.1*9.2
=(10.1-0.1)*9.2
=10*9.2
= 92
