1. Lesson 3-6 Example 2 3-6 Example 2 Find the difference 572 and 286. Use expanded form. 1.Write the first number in expanded form. 500 + 70 + 2

2. Lesson 3-6 Example 2 3-6 Example 2 Find the difference 572 and 286. Use expanded form. 2.Write the second number in expanded form. 200 + 80 + 6

3. Lesson 3-6 Example 2 3-6 Example 2 Find the difference 572 and 286. Use expanded form. 3.Put the numbers in vertical form. 500 + 70 + 2 − 200 + 80 + 6

4. Lesson 3-6 Example 2 3-6 Example 2 Find the difference 572 and 286. Use expanded form. 4.Look at the ones column. Because 6 > 2, you will need to regroup. 500 + 70 + 2 − 200 + 80 + 6

5. Lesson 3-6 Example 2 3-6 Example 2 Find the difference 572 and 286. Use expanded form. 5.Rewrite the top number. Move 10 from the tens column to the ones column. Now subtract the ones column. 6 500 + 60 +12 − 200 + 80 + 6

6. Lesson 3-6 Example 2 3-6 Example 2 Find the difference 572 and 286. Use expanded form. 6.Look at the tens column. Because 60 < 80 you will need to regroup. 6 500 + 60 +12 − 200 + 80 + 6

7. Lesson 3-6 Example 2 3-6 Example 2 Find the difference 572 and 286. Use expanded form. 7.Rewrite the top number. Move 100 from the hundreds column to the tens column. Now subtract the tens column. 6 400 +160 +12 − 200 + 80 + 6 80 +

8. Lesson 3-6 Example 2 3-6 Example 2 Find the difference 572 and 286. Use expanded form. 8.Find the differences of the hundreds column. 6 400 +160 +12 − 200 + 80 + 6 80 +200 +

9. Lesson 3-6 Example 2 3-6 Example 2 Find the difference 572 and 286. Use expanded form. 9.Write the expanded form number in standard form. 200 + 80 + 6 = 286
