(795 – 358

उपयोग की गई अवधारणा:

7 की चक्रीयता 4 है

3 की चक्रीयता 4 है

गणना:

795 = 7(4 × 23) + 3 = 1 × 73 = 343

⇒ 795 की इकाई अंक = 3 

358 = 3(4 × 14) + 2 = 1 × 32 = 9

⇒ 358 की इकाई अंक = 9 

(795 – 358) की इकाई अंक = 3 – 9 = -6

नोट: 3 - 9 = -6 क्योंकि हमें यूनिट अंक ढूंढना है। इकाई अंक खोजने के लिए हमें दसवें अंक से 1 उधार लेना होगा। इसलिए, 13 - 9 = 4
