Question

整數(shù)的運(yùn)算定律對(duì)小數(shù)運(yùn)算不適用．________．

Answer 1

錯(cuò)誤
分析：整數(shù)的運(yùn)算定律對(duì)于小數(shù)、分?jǐn)?shù)同樣適用．由此解答．
解答：整數(shù)的運(yùn)算定律對(duì)于小數(shù)、分?jǐn)?shù)同樣適用．
例如：7.8+5.3+2.2根據(jù)加法交換律和結(jié)合律進(jìn)行簡(jiǎn)算；
7.8+5.3+2.2
=7.8+2.2+5.3
=10+5.3
=15.3；
因此，整數(shù)的運(yùn)算定律對(duì)小數(shù)運(yùn)算不適用．此說(shuō)法是錯(cuò)誤的．
故答案為：錯(cuò)誤．
點(diǎn)評(píng)：此題考查的目的是明確整數(shù)的運(yùn)算定律對(duì)于小數(shù)、分?jǐn)?shù)同樣適用．由此解決問(wèn)題．
