  2. 3-7 Example 2 Lesson 3-7 Example 2 Find the difference of 702 and 589. Use expanded form. 2.Write the second number in expanded form. 500 + 80 + 9

  3. 3-7 Example 2 Lesson 3-7 Example 2 Find the difference of 702 and 589. Use expanded form. 3.Put the numbers in vertical form under the correct place values. 700 + 2− (500 + 80 + 9)

  4. 3-7 Example 2 Lesson 3-7 Example 2 Find the difference of 702 and 589. Use expanded form. 4.Find the difference of each place-value column. Because you cannot subtract 9 from 2, you need to regroup. Move 1 hundred to the tens column. Then move 1 ten to the ones column. Now there are 12 ones and 9 tens. 700 + 2 = 600 + 100 + 2 = 600 + 90 + 12

  5. 600 + 90 + 12− (500 + 80 + 9) 100 + 10 + 3 = 113 3-7 Example 2 Lesson 3-7 Example 2 Find the difference of 702 and 589. Use expanded form. 5.Subtract each column.
