Question

絕對(duì)值小于的所有負(fù)整數(shù)的和為                        。

Answer 1

-10

根據(jù)絕對(duì)值性質(zhì)可知，絕對(duì)值小于4的所有負(fù)整數(shù)為：-1，-2，-3，-4，從而求得它們的和．
解：根據(jù)絕對(duì)值性質(zhì)得，絕對(duì)值小于4的所有負(fù)整數(shù)為：-1，-2，-3，-4，所以（-1）+（-2）+（-3）+（-4）=-10．
此題考查了絕對(duì)值的性質(zhì)，要求掌握絕對(duì)值的性質(zhì)及其定義，并能熟練運(yùn)用到實(shí)際當(dāng)中．絕對(duì)值規(guī)律總結(jié)：一個(gè)正數(shù)的絕對(duì)值是它本身；一個(gè)負(fù)數(shù)的絕對(duì)值是它的相反數(shù)；0的絕對(duì)值是0．
