### QUESTION 1 of 10

In this activity, we will learn how to add two numbers using two methods.

e.g. Add the numbers below together:

22478 + 15622

Method 1:

1. Add the ten thousands, 20000 + 10000 = 30000.

2. Add the thousands, 2000 + 5000 = 7000.

3. Add the hundreds, 400 + 600 = 1000.

4. Add the tens, 70 + 20 = 90.

5. Add the ones, 8 + 2 = 10.

6. Add the total for the answer below, making sure to line up the numbers in their correct place value columns.

 + 2 2 4 7 8 1 5 6 2 2 3 0 0 0 0 7 0 0 0 1 0 0 0 9 0 1 0 3 8 1 0 0

Method 2:

This is column addition with regrouping if a column adds to 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.

So in summary:

22478 + 15622 = 38100
