1、相邻数,相邻数的概念,释义：在从小到大依次排列的自然数中，一个数前面和后面相互邻近的两个数就是该数的相邻数。实际上就是某个数加一减一所得的两个数。 示例：比如5，前面相邻是4，后面是6，则5的相邻数就是4和6。 形象地说：就是问你比你年纪大一岁和小一岁的小朋友分别是几岁？,1,3,4,5,动物新家,2,0,1,2,3,4,5,6,7,8,9,10,我会填,2,3,4,我会摆,2的相邻数是 和 .,3的相邻数是 和 .,4的相邻数是 和 .,1,3,2,4,3,5,1的相邻数是 和 .,0,2,6的相邻数是 和 .,7的相邻数是 和 .,8的相邻数是 和 .,5,7,6,8,7,9,5的相邻数是
