**Addition of four digit numbers with carry**

**Question 1**

**Add the following : –**

**Explanation**

**Adding the digits at ones place ,**

**8 + 3 = 11**

**Since the number is more than 9, we carry over 1**

** Adding the digits at tens place , and the carry over of 1**

**1 + 9 + 2 = 12**

**Since the number is more than 9, we carry over 1**

**Adding the digits at hundreds place, and the carry over of 1 **

**1 + 3 + 6 = 10**

**Since the number is more than 9, we carry over 1 **

**Adding the digits at Thousands place, and the carry over of 1**

**Add 1 + 5 + 8 = 14**

** Hence, the sum of the given numbers is 14021**

**Question 2**
