Question

計(jì)算小數(shù)加減法時(shí)要把小數(shù)的末位對(duì)齊．________．

Answer 1

錯(cuò)誤
分析：小數(shù)加減法的計(jì)算法則是：小數(shù)點(diǎn)對(duì)齊，再按整數(shù)加減法的方法進(jìn)行計(jì)算．據(jù)此解答．
解答：計(jì)算小數(shù)加減法時(shí)要把小數(shù)點(diǎn)對(duì)齊，就是數(shù)位對(duì)齊，所以計(jì)算小數(shù)加減法時(shí)要把小數(shù)的末位對(duì)齊，錯(cuò)誤．
故答案為：錯(cuò)誤．
點(diǎn)評(píng)：本題考查了學(xué)生小數(shù)加減法的計(jì)算法則．
