Question

絕對(duì)值不等的異號(hào)兩數(shù)相加，取

絕對(duì)值較大加數(shù)

的符號(hào)，并用

較大的絕對(duì)值

減去

較小的絕對(duì)值

．

Answer 1

分析：利用異號(hào)兩數(shù)相加的法則計(jì)算即可得到結(jié)果．

解答：解：異號(hào)兩數(shù)相加，絕對(duì)值不等的異號(hào)兩數(shù)相加，取絕對(duì)值較大加數(shù)的符號(hào)，并用較大的絕對(duì)值減去較小的絕對(duì)值．
故答案為：絕對(duì)值較大加數(shù)；較大的絕對(duì)值；較小的絕對(duì)值

點(diǎn)評(píng)：此題考查了有理數(shù)的加法，熟練掌握加法法則是解本題的關(guān)鍵．
