在数轴上表示﹣2的点与表示3的点之间的距离是（　　）                            

A．5                            B．﹣5                         C．1                            D．﹣1

答案

A 【考点】数轴．                                                                             

【分析】根据正负数的运算方法，用3减去﹣2，求出在数轴上表示﹣2的点与表示3的点之间的距离为多少即可．                                                                             

【解答】解：3﹣（﹣2）                                                                         

=2+3                                                                                                  

=5．                                                                                                  

所以在数轴上表示﹣2的点与表示3的点之间的距离为5．                             

故选A                                                                                                

【点评】此题主要考查了正负数的运算方法，关键是根据在数轴上表示﹣2的点与表示3的点之间的距离列出式子．
