### QUESTION 1 of 10

In this activity, we will learn how to add two large numbers using column addition and regrouping.

e.g. Add the numbers below together:

22478 + 15622

Set the numbers out in columns and add vertically, remembering to regroup if a column adds up 10 or more.

1. Add the ones, 8 + 2 = 10. Write the 0 in the ones column, and regroup the 1 under the tens column.

2. Add the tens column, including the regrouped 1. Add 7 + 2 + 1 = 10. Write the 0 in the tens column and regroup the 1 under the hundreds column.

3. Add the hundreds column, including the regrouped 1. Add 4 + 6 + 1 = 11. Write the 1 in the hundreds column and regroup the 1 under the thousands column.

4. Add the thousands column, including the regrouped 1. Add 5 + 2 + 1 = 8.

5. Add the ten thousands column, 2 + 1 = 3.

In summary:

22478 + 15622 = 38100
