Question

【題目】小數(shù)加減法的計(jì)算與整數(shù)加減法的計(jì)算相同，就是要把相同數(shù)位對(duì)齊也就是要把　 　．

Answer 1

【答案】小數(shù)點(diǎn)對(duì)齊

【解析】

試題分析：依據(jù)小數(shù)加減法的計(jì)算方法：計(jì)算小數(shù)加、減法，先把各數(shù)的小數(shù)點(diǎn)對(duì)齊（也就是把相同數(shù)位上的數(shù)對(duì)齊），再按照整數(shù)加、減法的法則進(jìn)行計(jì)算，最后在得數(shù)里對(duì)齊橫線上的小數(shù)點(diǎn)點(diǎn)上小數(shù)點(diǎn)解答．

解：在進(jìn)行小數(shù)加減法計(jì)算時(shí)：首先要把相同數(shù)位對(duì)齊（也就是把小數(shù)點(diǎn)對(duì)齊），

故答案為：小數(shù)點(diǎn)對(duì)齊．
