Add. See Example.

9,339 + 471 + 6,883

Example

Add: 9,835 + 692 + 7,275

Strategy We will write the numbers in vertical form so that corresponding place value columns are lined up. Then we will add the digits in each column, watching for any sums that are greater than 9.

WHY If the sum of the digits in any column is more than 9, we must carry.

Solution

We write the addition in vertical form so that the corresponding digits are lined up. Each step of this addition is explained separately. Your solution need only look like the last step.

The sum is 17,802.
