What is the remainder when the positive integer x is divided by 6?

 

 

(1)  When x is divided by 2, the remainder is 1; and when x is divided by 3, the remainder is 0.

 

 

(2)  When x is divided by 12, the remainder is 3.

??????

how to have the results?

(1) y=2a+1,y=3b,说明y是3的倍数,而且是奇数,所以除6肯定余3

(2)除12余3,那除6也余3了
