Explanation

Given information:

The numbers 12,554, 22,066, 11,460, 20,005 and 4,303.

Formula used:

Use the following steps to add the numbers.

Step 01: First write all the numbers in columns such that all the place values are aligned.

Step 02: Add the digits in each column, starting from the right.

If the total is a two-digit number then write its unit digit under the column which is added and carry the tens digit to the column to the left.

Step 03: Check the addition of the number by adding the numbers again from bottom to top.

Calculation:

To add the given numbers, align the numbers as,

12,554     22,066      11,460     20,005+   4,303_

Add, the unit column, 4+6+0+5+3=18, the sum of the unit column is 18.

Write the unit digit 8 under the units column and carry the tens digit 1 to the tens column.

12,554     22,606      11,460     20,005+   4,303_               8

Now, add the numbers under the tens column along with the carry digit 1.

5+0+6+1=12

Write the unit digit 2 under the tens column and carry the tens digit 1 to the hundreds column.

12,554     22,606      11,460     20,005+   4,303_             28

Now, add the numbers under the hundreds column along with the carry digit 1.

5+6+4+3+1=19

Write 9 under the hundreds column and carry 1 to the thousands column.

12,554     22,606      11,460     20,005+   4,303_           928

Now, add the numbers under the thousands column along with the carry digit 1
